" Iris lemon-yellow, feet and bill black." 



In the pale yellowish-white colour of the under parts and tail- 

 end these birds agree with Bogotd skins, but are slightly smaller f". 

 In size they approach C. a. zeledoni, fi-om Chiriqui and Costa Rica ; 

 the latter form may, however, easily be distinguished by the bright 

 creamy-yellow belly, etc. 



A good series from Carthagena (the type locality of C. sclateri 

 Heine +) is required to show whether the slight ditt'erence in size 

 between birds from Bogota and Western Colombia is constant. 



C. a. affinis is confined to Colombia, ranging from near sea- 

 level up to about 5000 feet altitude. 



64. Cyanolyca pulchra Lawr. 



CyanocAtta palchra Lawrence, Ann. Lye. N. H. N. Y. xi. 1875, 

 p. 163 (Feb. 1876.— Quito, Ecuador). 



No. 2789. J ad. Tatama Mountain, 7600 ft., 9.X.08.— Wing 

 130; tail (moulting) about 135 ; bill 30 mm. 



" Iris, feet, and bill black." 



So far as I am aware this is the second known specimen of 

 this fine species, which was described by Mr. Lawrence from a 

 single Quito skin in his collection. The bird corresponds exactly 

 to the original description with the sole exception that the smokj^- 

 blackish chest shows a faint cobalt-bluish tinge. C. jndchra cannot 

 be confused with any other species. It differs from all the forms 

 of the C. armillaia group by the beautiful silvery bluish- 

 white colour of the crown and nape, terminated behind by a 

 distinct cross-band of bright ultramarine blue; by the dull 

 brownish-black upper back, without any blue tinge ; by the much 

 duller cobalt-blue throat-patch ; by lacking the black jugular 

 crescent, so conspicuous a feature in all of its allies ; by the smoky- 

 blackish chest, and much duller bluish belly, etc. Moreover, the 

 bill is much stouter and larger, while the tail, on the other hand, 

 is much shorter. 



There can be no doubt that G. pulchra is an excellent species, 

 not much like any other member of the genus. 



* Ridgway (Bull. U. S. Mus. no. 50, pt. iii. p. 305), with a query, refers the above 

 quotation to the Central American race C. a. zeledoni Ridgvv. (Auk, xvi. 1899, 

 p. 255. — Talamanca, Costa Rica). But as specimens from Carthagena, N. Colombia, 

 agree with C. a. affinis from Bogota etc., those from Truando and Nercua most 

 certainly belong also to the latter, inasmuch as the fauna of those districts is 

 essentially the same as that of the San Juan River.
