30. XANIHURA. ]31 



dark greeu, the four outer oues on each side bright yellow : crown 

 of head and nape deep cobalt, the frontal plumes rather stiff and 

 erect, and separated from the rest of the crown by a line of white ; 

 lores and sides of face black, a spot above and below the eye and a 

 large patch at tho base of the lower ma7idible deep cobalt ; entire 

 throat and fore neck black ; rest of under surface of body pure bright 

 yellow, without any shade of green anywhere, the under wing- coverts 

 yellow like the breast. Total length 11-8 inches, culmen 1-05, 

 wing 4-6, tail 6, tarsus 1"5. 



Obs. The Venezuelan species seems to be quite distinct, and will, 

 I believe, be found to bear Dr. Dubois's name of cceruleocejjhala. At 

 the same time the characters given by him are not the true distinc- 

 tive ones of the species ; for the bird has ver\- long frontal plumes, 

 not sJiort, as in the Guatemalan species ; and, again, there is a dis- 

 tinct line of white across the crown, which Dr. Dubois states to be 

 absent in his typical specimen. This may be due to defective prepa- 

 ration of the skin ; but the pure yellow abdomen (" abdomen flavis- 

 simum," Dubois), being such a peculiar character of the Venezuelan 

 bird, obliges me to refer the specimens in the Museum to X cceru- 

 leoceplmla, notwithstanding the discrepancies in the description.
