Genus CICHLHERMINIA Bonaparte. 



CichlJierminia Bonaparte, Compt. Rend., xxxviii, 1854, 3 (Notes Orn. Coll. 

 Delattre, p. 26). (Type, by elimination, Turdus Vherminieri Lafresnaye.) 

 Cichlervnnia (emendation) Sclater, Proc. Zool. Soc. Lond., 1859, 335. 



Large, stoutly-built, short-tailed, long-legged Turdidse with large 

 and stout bill, color uniform brown above, brown with pointed spots 

 of white below. 



Bill large and stout, shorter than head, about as broad as deep at 

 frontal antise; exposed culmen about as long as middle toe without 

 claw, or slightly shorter, rather strongly convex from the nearly 

 straight basal portion, the tip of maxilla distinctly but not strongly 

 uncinate ; gonys straight or very faintly convex, ascending terminally, 

 slightly longer than mandibular rami; maxillar}^ tomium faintly con- 

 cave in middle portion, still more faintly convex subbasally, ver}^ dis- 

 tinctly notched subterminally. Nostril oval or ovate, occupjdng 

 about lower half of exposed portion of nasal fossa^, overhung b}" con- 

 cave mem})rane, posteriorly nearly or c{uite in contact with frontal 

 feathering. Rictal bristles very distinct, those near nostrils especially 

 so ; loral and frontal feathers without bristly points. Orbital region 

 naked, or partly so. Wing rather long and pointed, the longest pri- 

 maries exceeding longest secondaries by length of middle toe (with- 



o The only specimen seen from the Volcan de Irazii is very different in coloration 

 from any other specimen examined, but I am satisfied that the coloration is abnormal, 

 indicating a condition of partial albinism. It bears in Mr. Cherrie's handwriting on 

 the label the name Zeledonia insperata Cherrie and, should other specimens from 

 Irazu prove to be like it in coloration, that name would of course be available for it 

 as representing a distinct form, which I consider altogether unlikely, since the Volcan 

 de Irazii is intermediate in position between the volcanoes of Poas and Chiriqui, 

 the birds of which are, so far as I am able to see, precisely alike in coloration. The 

 Irazii specimen may be described as follows: 



Similar in pattern of coloration to Z. coronata (from the Volcan de Pods and Volcan 

 de Chiriqui), but the dark olive of back, scapulars, etc., replaced by rather light 

 tawny-olive; that of wings and tail by light grayish brown (between broccoli lirown 

 and isabella color); deep slate-color of sides of head and under parts replaced by 

 drab-gray; bill, legs, and feet pale brown instead of blackish. 



The tawny crown-patch is somewhat lighter in tone and broader, but its increased 

 width may be owing to greater spreading apart of the feathers in making up the skin. 

 The broad black lateral crown-stripes of normal Z. coronata are indicated by decidedly 

 narrower stripes of dark sooty grayish.
