5 Pileo co/icolore plumbeo : superciliis albis. 



Hub, Cartagena (Mus. Berol.). 



The type-specimens in the Berhn Museum are the only examples 

 I have seen of this species ; ^Yhich may be at once distinguished from 

 all the precedmg by its white supercihaiy stripe. 



Remarks on the Arrangement of the Jacamars (Gal- 



bueid.e), with Descriptions of some New Species. 



By Philip Lutley Sclater, M.A., F.Z.S. 



Since I wrote some articles on the Galbulidoi, which appeared in 

 Sir AVilliam Jardine's Contributions to Ornithology, and the little 

 Synopsis of the family afterwards printed apart, 1 have lost no op- 

 portunity of examining specimens of these birds in several museums 

 which I have visited. In so doing I have acquired some additional 

 information concerning them, which I now purpose bringing before 

 the Society, together with characters of what I believe to be three 

 hitherto unrecognized species. 



Genus 1. Galbula. 



1. viridis. Lath. Synopsis of the Galbiilidce, p. 2. sp. 1. 



Dr. Cabanis, in his article upon these birds in Ersch and Gruber's 

 Encyclopiidie, calls the Amazon specimens true ' viridis,' and sepa- 

 rates the Cayenne and Guiana bird from them, under Swainson's title 

 ' viridicauda.' I cannot myself discover much difference between 

 them. Prince C. L. Bonaparte quotes as a species 'quadricolor,' Ver- 

 reaux, a ]MS. name for which no specific characters have been pub- 

 lished. A specimen so labelled in the British Museum is from Peru, 

 but seems to me barely separable from G. viridis. 



2. rvfoviridis, Cab. Enc. d. W. u. K. vol. lii. sect. 1. p. 308. 

 G. maculicmida, Synopsis, p. 2. sp. 2. 



Dr. Cabanis' name has, I believe, a few months' precedence in 

 point of date over my ' tnaculicauda,' and must therefore be used for 

 this species. As additional localities, I have now : River Tocantins, 

 Brazil (Mr. Wallace), and Bolivia (Bridges, in Mus. Brit.). 



3. melanogenia, Sclater. Synopsis, p. 3. sp. 3. 



I have since seen other specimens of this species, both male and 

 female, all from Central America. 



4. ruficauda, Cuv. Synopsis, p. 3. sp. 4. 



Add, as localities : Tobago (Kirk) ; Cumana (Dyson^ ; Cartagena 

 (Mus. Berol.). 



These four species are, as I have already remarked (Cont. to Orn . 

 1852, p. 93), very closely allied to one another, but may be distin- 

 guished by the colouring of the rectrices. They are not, however, 

 placed together in Prince C. L. Bonaparte's arrangement in his 

 Conspectus Zygodactylorum . 



5. tombacea, SpLx {cyaaeseens, Deville). 



From the Upper Amazon and eastern provinces of Peini.
