DEFINITIONS

CIRCUS
(Accipitridae; Ϯ Western Marsh Harrier C. aeruginosus) Gr. κιρκος kirkos  partly mythical hawk, named for its circling flight  < κιρκος kirkos  circle, mentioned by many classical authors and later identified with the Hen Harrier (cf. κιρκη kirkē  bird referred to by Aelianus, different to κιρκος kirkos but not otherwise identified); "BUSARD. Circus.  { Le bec courbé dès la base; la tête plate en dessus, et garnie de plumes; la base du bec recouverte d'une cire; les ailes très-longues; la première penne de l'aile, très-courte; le tarse long et grêle." (de Lacépède 1799); "Circus Lacépède, Tabl. Ois., 1799, p. 4. Type, by subsequent designation, Falco aeruginosus Linné. (Lesson, Man. d'Orn., 1, 1828, p. 105.)" (Peters, 1931, I, p. 264).

assimile / assimilis
L. assimilis  similar, like.  Indicates a close resemblance or relationship to another, but not necessarily congeneric, species.  Over forty forms have been given this epithet; only some examples follow.
● "4. Collocalia francica assimilis subsp. n.   Rücken und Unterseite etwas heller als bei den beiden vorhergehenden Formen [Collocalia francica towsendi [sic]] und mit der typischen Form übereinstimmend; von dieser ist C. fr. assimilis indessen durch die dunklere Färbung des Oberkopfes und die durchschnittlich geringere Grösse wohl unterschieden." (Stresemann 1912) (subsp. Aerodramus spodiopygius).
● "Tanagra (Arrémon, Vieillot; Embernagra, Lesson) assimilis, Boiss. — Cette espèce est très-voisine par sa coloration de l'Arrémon à collier de Vieillot, ou oiseau silencieux de Buffon [Arremon taciturnus], mais elle est d'un tiers plus forte et n'a pas de collier noir sur la poitrine." (Boissonneau 1840) (Arremon).
● "91. CUCULUS ASSIMILIS.   Allied to C. flavus [= syn. Cacomantis merulinus].  ...  Hab. Aru Islands.  ♀ in Mr. Wallace's Collection." (G. Gray 1858) (syn. Cacomantis variolosus infaustus).
● "Alcyone Assimilis (allied kingfisher).—The specific name which I have applied to this species has reference to the similarity which exists between our A. Pusilla and itself, but the general dulness of color throughout, and the absence of the slightest tinge of green sufficiently distinguish it." (Diggles 1873) (syn. Ceyx pusillus).
● "41. Chlorostilbon assimilis, sp. nov.  ...  This species is somewhat like C. melanorhynchus, Gould, but is smaller; the bill is much shorter and comparatively weaker; the crown is uniform in color with the back, not brilliant as in melanorhynchus, the latter species is also more golden on the abdomen, and has the tail less forked with the feathers narrower." (Lawrence 1861) (Chlorostilbon).
● “CIRCUS ASSIMILIS, (NOBIS).  ...  In general form and colour it closely resembles the females of the true Circi, particularly of our own British species, that of the C. ranivorus of Africa, and of the C. histrionicus.  It is, however, a larger and more powerful bird than any of these.” (Jardine & Selby 1828) (Circus).
● "Genus Picus, L., as restricted to the pied species forming the division Dendrocopus of Swainson.  The Indian species of this group are treated of in XIV, 916, so far as we were then cognisant of them.  We have since learned of two others described from the "Himalaya," viz. P. assimilis, Natterer,—like P. himalayanus (No. 287), but with the scapulary feathers white, and some other distinctions,—and P. scintilla, Lichtenstein" (Blyth 1849) (Dendrocopos).
● "5 GERYGONE ASSIMILIS, Buller. — In form and color this bird is hardly distinguishable from G. flaviventris, although somewhat larger." (Buller 1865) (syn. Gerygone igata).
● "Eriocnemis assimilis.  ...  Elle est très-voisine de l'E. aureliæ. Bourc. et Mulsant, mais elle a les plumes duveteuses des tarses, d'un jaune-brunâtre uni, tandis que celles d'aureliæ sont blanches avec quelques-unes carnées ou roussâtres à la base.  Il y a entre ces deux espèces la même différence qui existe avec l'Eriocnemis lugens et l'E. squamata de Gould, et celles-ci ont généralement été acceptées par les naturalistes comme de bonnes espèces." (Elliot 1876) (Haplophaedia).
● "MUNIA CASTANEOTHORAX ASSIMILIS, subsp. n.   Differs from M. castaneothorax (Gould) in having the chestnut band on the chest much darker in colour, and the upper tail-coverts rich chestnut-brown." (Mathews 1910) (syn. Lonchura castaneothorax).
● "MALURUS ASSIMILIS, sp. nov.  ...  The above-described species belongs to that section of the genus Malurus in which the adult males are distinguished by their chestnut shoulders, and is more closely allied to M. lamberti." (North 1901) (subsp. Malurus lamberti).
● "As the species now exhibited closely assimilates to the M. macroptera, I propose to designate it as  MICRŒCA ASSIMILIS.  ...  Nearly allied to but much less in size than M. macroptera, Vig. and Horsf., and from which it may also be distinguished by the base of the outer tail-feathers being brown." (Gould 1841) (subsp. Microeca fascinans).
● "Myrmotherula assimilis Pelzeln. N. 931. partim.  ...  M. Hauxwellii Sclater persimilis sed cauda longiore rectricibus 12 predita, secundariis et tectricibus caudae superioribus albo haud maculatis, differt" (von Pelzeln 1868) (Myrmotherula).
● "26.  Pachycephala assimilis (J. Verr. et O. des Murs.)  ...  Cette espèce se rapproche beaucoup du Pachycephala falcata [= subsp. P. rufiventris] de Gould, qui provient de la Nouvelle-Hollande; mais, en les comparant, il est impossible de les confondre, ce qui nous a décidés à lui imposer le nom d'assimilis." (J. Verreaux & des Murs 1860) (syn. Pachycephala rufiventris xanthetraea).
● "On a former occasion, (S. F. Vol. I., p. 429, Dec. 1873) I discriminated the Ceylon Phodilus and pointed out clearly wherein it differed from the Himalayan birds.  I did not then name it, because I was under the impression that Malayan specimens differed similarly.  This, however, does not seem to be the case, and having now seen a second Ceylon specimen, presenting the same specific characters as the first, I desire to propose for it provisionally the name of PHODILUS ASSIMILIS." (Hume 1877) (Phodilus).
● "1274.  Meliornis novaehollandiae assimilis subsp. n.   Victorian White-bearded Honey Eater.  Mathews, Handlist No. 799 (pars).  Differs from M. n. novaehollandiae in its darker coloration on the head and with fewer stripes on the belly..  Type: Victoria, No. 9062." (Mathews 1912) (syn. Phylidonyris novaehollandiae campbelli).
● "BROADBENTIA FLAVA.  YELLOW HONEY-EATER.   ...   Collected near Cairns, North Queensland, in July, 1911, and is the type of B. f. assimilis."(Mathews 1925). Perhaps only a lapsus for addenda (syn. Stomiopera flava addenda).
● "Rhynchocyclus assimilis Pelzeln N. 220?  ...  Rh. sulphurescente (Spix.) similis sed minor et rostro breviore, latiore, magis acuminato." (von Pelzeln 1868) (Tolmomyias).
● "TROGON ASSIMILIS.  ...  Nearly allied to Trogon personata, but differing from that species in the tail being nearly black, in the transverse markings being very slight and in the extremities more largely tipped with white; the freckled markings of the wing are also much more minute." (Gould 1846) (subsp. Trogon personatus).
