154 MR. O. SALVIN ON THE BIRDS OF VERAGUA. [Jan. 24, 



has as yet reached me. The shining forehead is considerably darker 

 and of a bluer shade, the bill longer, and the under plumage blacker 

 than in a New Granadan specimen of D. ludovicice before me ; the 

 wings, too, are shorter. Should the receipt of additional speciaieus 

 confirm the constancy of these distinctions, I propose for this race 

 the name of Dorifera verac/uensis.

Santiago de Veragua and Cordillera de Tole. 



A series of specimens of both sexes from Veragua and also from 

 Costa Rica have been sent by Arce. These I have compared with 

 Mr. Gould's specimens of H. jacula ; and we both consider them 

 identical with that species. Since then Mr. Lawrence has sent the 

 types of his Heliodoxa henryi to Mr. Gould for examination. They 

 prove to be immature birds identical with our specimens ; hence 

 this name must be considered synonymous with JI, jacula. This is 

 by no means an isolated case of New Granadan and Costa Rican 

 specimens being specifically identical, though their range appears to 

 be interrupted at the Isthmus of Panama.

 ii. pi. IIG. 



Li a previous collection Arce sent two specimens of a bird of this 

 genus and closely allied to this species from Tucurriqui, in Costa 

 Rica. Not having good specimens of the true il/. albocoronata with 

 which to compare them, I left them till I could make a more satisfac- 

 tory examination. Since then Mr. Lawrence has described a female 

 bird from Angostura, in Costa Rica, under the name of Panychlora 

 parvirostris, and afterwards sent the type to Mr. Gould for inspec- 

 tion. Mr. Gould pronounced this bird to be the female of a Micro- 

 chera. Having now a good series of the true M. albocoronata I am 

 able to point out the following diiferences between it and the Costa 

 Rican bird : — The latter has the rich vinous ))urple of tlie back deci- 

 dedly brighter, the white crown seems to extend further over the 

 back of the head, and the black band of the apical third of the outer 

 rectrices is wider and the inner margin not so sharply defined. The 

 under plumage of M. albocoronata is decidedly darker, being almost 

 black instead of the same shade as the back. These differences are 

 sufficient to separate the Costa Rican from the Veraguan Inrd ; and 

 fur the former the name Microchera j^arvirostris must be taken, 

 though the specific one does not convey the character intended. The 

 range of the two forms corresponds with that of the two C/ialybiircc 

 above mentioned.

This species has already been noticed by Mr. Lawrence in M'Le- 

 annan's Panama collections. I have also specimens obtained by 

 Arce at Tucurriqui.
