CYANOCORAXo 589 



Total length 360 mm., exposed culmen 27, wing 196, tail 167, 

 tarsus 51. 



This species is not repiesented in the McC^onnell collection, and 

 the description is taken from the specimen in the British Museum 

 collected by the late Sir Richard Schombnrgk. Having compared 

 this sjecimen (Cabanis^s ^JP^) '^vith nine others in the iSational 

 Museum, from East Peru, Ecuador, and C'olombia, I find it to be 

 much paler in coloration. I propose, therefore, the British Guiana 

 bird be separated under Cabanis's name.

Habits. Schomburgk writes (Reis. Guian. iii. p. 683) of this 

 species as being rarer than C. rai^anus, which it surpasses in bril- 

 liancy of plumage. He only had one specimen in his collection, 

 which he obtained in the Canuku Mountains.
