210 DR. P. L. SCLATER ON A NEW LIPAUGUS. [May 28, 



collection of the British Museum, which seems to helong to a very- 

 distinct new species of the genus Lipauyus * of Boie, I take the op- 

 portunity of giving a list of the members of this peculiar American 

 genus now known to me, together with the characters of the new 

 bird, which I propose to call 



LiPAUGTTS SUBALARIS. 



Viridescenti-oUvaceus, dorso hno, ventre et cauda cinerascentio- 

 ribus, Cauda fere tola cinerea ; crisso albicante ; pilei semi- 

 cristati plumis interne tiigris : gutturis et pectoris phimarum 

 scapis conspicue J/avicanti-albis : ^9/«<?rt2S axilhiribus et sub- 

 alaribus Icete citriiio-Jlavis : alis fusco-nigricantibus, extus dorso 

 concoloribus : rostro et pedibus nigris. 

 Hab. In rep. Equatoriana, ad ripas fl. Napo. 

 This Lipaugus will be easily recognized by the beautiful bright 

 yellow colour of the axillaries and under wing-coverts and the slightly 

 crested head, the feathers of which are black underneath. In struc- 

 ture it appears to be a member of the group Aidia : the outer and 

 middle toes being completely united to the end of the second pha- 

 lange, and the form otherwise resembling that of Lipaugus hypo- 

 pyrrhus. The single example in the collection of the British Mu- 

 seum, acquired in 1857, is labelled "Rio Napo." 



I have examined specimens of nine species of this genus, which 

 may be arranged as follows in three sections. 



a. Lathria.

 ternis ad basin conjunctis.
