 ventris, and C. canescens. Crotophaga ani is the only West- 

 Indian representative, and also belongs to Cozumel. It is

 on the Bonin Islands, calling at some of the Seven Islands 

 both in going and returning. Collections were made at the

Haha-Shima, or Hillsborough Island, one of the Coffin 

 Islands or Baily Islands, about 40 miles south of Peel 

 Island.
