DEFINITIONS

MALACONOTUS
(Malaconotidae; Ϯ Grey-headed Bush-shrike M. blanchoti) Gr. μαλακος malakos  soft; -νωτος -nōtos  -backed  < νωτον nōton  back; "Plumage soft and rather full" (Fry et al. (eds.) 2000); "It is important, however, that we should separate the African Thamnophili, from those of the new world; because we shall presently attempt to show, that they both lead to different groups; and because a peculiar distinction will be observed between them; the lateral scales on the tarsi of the African species, are formed of entire laminæ, while, in those from America, they are small and very numerous; in the first, the rictus is strongly bearded, in the last it is smooth. The name of M. Vieillot I shall therefore confine to such species as inhabit America, agreeably to the plan adopted by M. Temminck; while those of Africa will form the Genus Malaconotus, and may be represented by the T. olivaceus of M. Vieillot." (Swainson 1824); "MALACONOTUS   ...   Type. La Pie-grieche blanchot" (Swainson 1827); "Malaconotus Swainson, 1824, Zool. Journ., 1 (1825), p. 40. Type, by original designation, T.[. . . ?] olivaceus "Vieillot" Swainson = La Pie-Grieche blanchot, LeVaill. (see Swainson, 1827, Zool. Journ., 3, (1828), p. 163) = Malaconotus blanchoti Stephens." (Rand in Peters 1960, IX, 338).

SCI Name: Malaconotus lagdeni centralis
centralis
L. centralis, centrale  central, in the middle  < centrum  middle point, centre  < Gr. κεντρον kentron  sharp point, stationary point of a pair of compasses.  A good proportion of the names here refer to forms collected in "Central Africa," i.e. the eastern Congo and the Rift Valley lakes (e.g. subsp. Bradypterus baboecala, subsp. Chlorocichla flaviventris, subsp. Malimbus rubricollis, subsp. Sarothrura pulchra, subsp. Turdus pelios).  Some further examples follow.
• "Dieselbe steht in Bezug auf Grösse zwischen cardinalis und massaicus in der Mitte." (Neumann 1900) (subsp. Dendropicos fuscescens).  
• "Distribution. Endemic to Peru on east Andean slope from Río Huallaga through Pasco to Junín west of the Río Ene and north of the Río Mantaro  ...  The scientific name reflects the range of this species near the geographic center of Peru." (Hosner et al. in M. Isler et al. 2020) (Grallaria).
• "Intermediate in size between N. f. flavicollis (Vieill.) and N. f. melanoxantha (Lcht.)" (Hellmayr 1907) (subsp. Hemithraupis flavicollis).
• "These birds are intermediate between N. famosa and N. cupreonitens, and resemble birds labelled by Neumann in the Tring Museum with the MS. name Nectarinia famosa centralis" (van Someren 1916) (subsp. Nectarinia famosa).
• "RANGE. —Eastern part of the central Solomon Islands (Kulambangra, New Georgia, Vangunu, and Gatukai)." (Mayr 1932) (subsp. Pachycephala pectoralis).
• "zentralbrasilianischen Hochlandes (Matto-grosso.  S. Goyaz.  N.-São Paulo.  W.-Minas Geraës)" (Hellmayr 1920) (subsp. Ramphocelus carbo).
• "the Central American form is named CICCABA VIRGATA CENTRALIS, subsp. nov.  ...  Chivela, Oaxaca, Mexico." (Griscom 1929) (subsp. Strix virgata).
• "Tang- (Dang-) la Range, Central Tibet, Tang-la Pass" (Sushkin 1926) (subsp. Tetraogallus tibetanus).
