TARSIGER
(Muscicapidae; Ϯ Golden Bush Robin T. chrysaeus) Mod. L. tarsus  leg, shank  < Gr. ταρσος tarsos  flat of the foot; L. -ger  bearing  < gerere  to carry; "Luscinidæ.  ...  Tarsiger chrysæus, [drawing nos.] 408, 409." (Hodgson 1844); “Genus Tarsiger, mihi.  Bill equal to head, straight, subdepressed, feeble, gradually widening from the tip; the upper mandible more than half exceeded by the nareal fosse, and much overlaid by the soft frontal plumes; tip of bill obtuse, and nearly unarmed; gape rather wide and ciliated; wings submedial, round rather than acuminate, firm; fifth quill longest; 4-6 and 3-7 respectively equal; alars and caudals wedged and mucronate; tail medial, rounded; tarse very elevate, slender and smooth; toes ambulant, simple; laterals unequal, hinder rather large; nails large, slender, simple; hind largest.  Exclusively monticolous; dwells in low brushwood solitarily, and is much on the ground, feeding chiefly on small ground insects.   ...   Type, T. chrysæus, mihi” (Hodgson 1845); "Tarsiger Hodgson, 1845, Proc.

• (Corvidae; syn. Cyanocorax † Plush-crested Jay C. chrysops) "Genus, CYANURUS.  ... Examples. - 1. C. cristatus.  2. Stelleri.  3. sordidus, Sw.  4. Floridanus, BON.  5. coronatus, Sw. Syn.  6. cyanopogon (Pl. col. 169).  7. pileatus (Ill. 58).  8. azureus (Ill. 168)  9. formosus (Pica formosa, Sw. Syn.)  10. cristatellus (Pl. col. 193), &c.  OBS. - This group is distinguished from the European and North Asiatic Jays by the upper mandible not being abruptly bent at the tip, or very distinctly notched, by the under being weaker, and by the powerful structure of the feet. The two outer toes also are almost equal. The first three species are aberrant, connecting this and the last group [Dysornithia]. The typical species are found only in the tropics of America and India" (Swainson 1832); "The genera Psilorhinus and Cissa, with Cyanocorax of South America, form a little group by themselves; and I consider that Mr. Strickland was quite justified in separating from the last the blue Jays of North America, which constitute his Cyanocitta, An. and Mag. Nat. Hist. 1845, p. 260; but as Corvus cristatus, Lin. is the type of Mr. Swainson's Cyanurus, I conceive that this must take precedence of Cyanocitta, Strickland" (Blyth 1846); "The type of the genus Cyanocitta of Strickland is Garrulus cristatus, Linn. as stated in precise terms by the founder of the genus  ... Again, the type of Cyanurus, Sw., is not Garrulus cristatus  ... This error was caused by Mr. G. R. Gray's [1855] unauthorized assumption that the first species in any author's list must necessarily be his type. But Swainson himself tells us that the first three species which he mentions (i.e. C. cristatus, C. stelleri, and C. sordidus) are "aberrant," and that the "typical" species are only found in the "tropics of America and India." It is obvious therefore that Cyanurus, Sw. (1831) = Cyanocorax, Boie (1826) as stated by Strickland l.s.c., and that Cyanocitta is the proper generic name for the "Blue Jays" of America" (P. Sclater & Salvin 1876); "Cyanurus Swainson, in Richardson, Faun. Bor.-Amer., 2, p. 495, Feb., 1832— no type designated. 2  ...   2 No valid type appears to have been designated for this genus.  ... Though, by common consent, Cyanurus has been regarded as synonymous with Cyanocorax, it seems advisable to formally propose a genotype to set this name at rest, and we suggest as such Corvus pileatus "Ill." = Pica chrysops Vieillot."
