Type in mnsenm of the State University of Kansas. 



Remarks. — Tliis species is mnch paler in coloration than all 

 otliers of the genus; in distribution of markings, it most resem- 

 bles F. moniliger, but it is very much paler throughout, the red 

 collar is more distinct than in that si)ecies, and the white sj)ot 

 in the lores is larger; the tail is brown instead of black, aud the 

 ochraceous coloring on the bases of the quill-feathers is twice the 

 extent that it is in F. moniliger; it is also longer than that spe- 

 cies in all its dimensions. 



When describing a new swift from Yucatan (antea, p. 245), I 

 alluded to the fact, that the State University of Kansas had pur- 

 chased a full series of the birds obtained in that country by Mr. 

 Geo. F. Gaumer. 



Since then Prof. F. H. Snow of the University has sent me 

 the collection for determination; besides the species above de- 

 scribed, of which there is but one example of each, it contains 

 many others of much interest.
