.45. It will be observed that while these two specimens agree closely in 

 measurements they are decidedly larger than C.psittaculus, as described 

 by Messrs. Gould and Salvin. 



22. Camarhynchus crassirostris Gould. 



Charles Island, two specimens; Indefatigable Island, two specimens; 

 Chatham Island, one specimen. 



In attempting to identify this species I am much puzzled by impor- 

 tant discrepancies in the descriptions given by Messrs. Gould, Salvin, 

 and Sharpe, all of which purport to be taken from the type specimen. 

 Thus, Gould says of the under parts: a The throat and breast cinereous 

 olive, with the middle of each feather darker; the abdomen, sides, and 

 under tail-coverts cinereous tinged with straw color." Mr. Salviu's 

 description of the same parts, translated, reads as follows : " Beneath 

 whitish, each feather of the throat and upper breast black in the mid- 

 dle." Then comes Mr. Sharpe, who says that the species " differs from 

 (J. variegatus in its uniform under surface* not being mottled with brown 

 streaks." The measurements given by these three authors vary no less 

 remarkably, as the following will show: 



Our specimens from Charles Island agree best as to coloration with 

 Mr. Salvin's description, though they resemble fairly the colored figure 

 in the Zoology of the Beagle (pi. 41); as to measurements, they cor- 

 respond best with those given by Gould. 



23. Camarhynchus prosthemelas Scl, and Salv. 

 Chatham Island, two specimens; Charles Island, two specimens; 

 James Island, four specimens. 



24. Camaryhnchus habeli Scl. and Salv. 

 Abingdon Island, two specimens. 



25. Camarhynchus townsendi, sp. nov. 



Sp. Char. — Similar to G. psittaculus, but paler and with a differently 

 shaped bill, the culmen broader and less arched, and commissure 

 straighter. 



Hab. — Charles Island.
