Lieutenant Robinson brought back eight specimens of this pretty 

 bird, which is named in honor of Mrs. Eobinson. It is closely allied to 

 AmazUia fdiciw of the adjacent uiainlaud, but is evidently distinct. I 

 have been unable at this time to compare the new species with males 

 of felieia', but, fortunately, Lieutenant Robinson stopped long enough 

 at Laguayra to collect six females of the latter, which are of excep- 

 tional interest here, as they were collected at about the same time as 

 those of the new form and are therefore iu exactly the same state of 

 plumage. Comparing females, then, the new form differs fvomfcJicia' in 

 having the posterior part of the crown and back reddish bronze instead 

 of green; in having the rump and upper tail coverts i)ractically with- 

 out metallic color; the tail less brilliant and steel black instead of blue 

 bla(;k; under tail-coverts uniform pale chestnut, without any metallic 

 green or steel blue feathers. This species is also larger than A.fclicice. 

 In the series of six females of the latter, the under tail-coverts are 

 mixed chestnut and metallic green or steel blue, with occasional gray- 

 ish feathers; the upper parts are brassy green in four of the speci- 

 mens, a wash of bronze on the back of the fifth, aid quite as pro- 

 nounced bronze in the sixth as in S]»ecimens of alicia', but the bronzy 

 appearance is probably due to a stain in this specimen, and covers more 

 of the rump and upper tail-coverts than in specimens of alicia'. 



The sexes are easily separable in this si)ecies and from its close 

 affinity to A. tohaci, A. erythronota, and A.fcUcia-, the same is doubtless 

 the case with them. The glittering green cap of the male sharply cut 

 oft" from the duller remainder of the crown will at once distinguish it 

 from the fenuile. — C. W. Iv.l
