nut ; a white mark behind the eye ; sides of the head and of the 

 neck blackish brown ; throat and breast pale chestnut, sides of 

 the abdomen of a deeper chestnut, middle of abdomen whitish. 

 It somewhat resembles the female D. evelynee, but is much 

 darker in its coloring.

 can Yrazei (J. Cooper). 



I wrote Dr. Frantzius requesting his opinion, whether this 

 bird was entitled to be considered a valid species or not ; in a 

 letter dated in February he replies as follows : 



" In my opinion Anthocephala castaneiventris, Gould, is the fe- 

 male of Panterpe insignis. My grounds for believing so are the 

 following: I have always received both from the same place, 

 La Candelaria. All the specimens of the former now in my 

 possession are females, and all the specimens of the Panterpe 

 are males. The bright crown in both is identical, as likewise 

 the shape of their bills." 



This coincides with the opinion expressed by me {Ann. N. Y. 

 Lye., Vol. viii. p. 45), but from which Mr. Salvin dissented. 



Since the receipt of Dr. Frantzius' letter, I have had my 

 opinion unsettled by specimens of Oreopyra calolo&ma received 

 Lately from the Smith. Inst., and now under examination, there 

 are two pairs apparently $ and ? ; one pair marked with same 

 date and locality. Mr. Salvin under 0. calolaima suggests that 

 A. castanciventris may be the female of that species, or possibly 

 distinct as given by Mr. Gould. I must confess that with nu- 

 merous specimens before me I am unable to arrive at a definite 

 conclusion as to the true status of the bird described as A. 

 castaneiventris. A pair of birds previously received, which 

 came together and are marked with same locality and date, I 

 considered to be 3 and ? of P. insignis, yet the female differs
