NoviTATEs Zooi,oGicAE XXVI. 1919. 149: 



of a new genus. It seems to me that the latter, Erythrothlypis Berl., must be 

 accepted, if Chrysothlypis is accepted. See also Chapman, Distr. Bird-Life, 

 Colombia,^. 617, 1917.

145. Rhamphocoelus inexpectatus Rothsch. = Ramphocelus inexpectatus. 



ShamphocoHtts inexpectatus Rothschild, Bull. B.O. Club, vi. p. xxxii. (February 1897 — Panama, 

 from preparation). 



Type : S ad., Panama. (Trade-skin, bought from K. Dunstall). 



Another specimen received afterwards agrees with the type, but the yellow 

 colour is less golden, more sulphur yellow, and there is not quite so much black 

 on the abdomen, there are no yellow edges to the feathers of the occiput, but 

 some on the sides of the head. 



146. Rhamphocoelus dnnstalli Rothsch. = Ramphocelus dunstalli. 



Shamphocoelus dunstalli Rothschild, Nov. Zool. 1895. p. 481 (Central America, probably Panama, 

 from preparation). 



Type : <J, Panama. (Trade-skin bought from K. Dunstall). 



A second male from the collection of Comte de Dalmas, bought in 1896 

 from Sciama, a feather-dealer in Paris, is perfectly similar to the type, only the 

 red of the underside a shade darker. 



It is strange that no more information has come forth about these two 

 birds. No collector has ever come across them. If they are two distinct species 

 they must have a very restricted habitat, and no doubt they came from the 

 same place, arriving about the same time (1895 and 1896) and being prepared 

 in the same manner.
