Specimens available from the Isle of Pines, and from tlio islands of 

 Porto Rico, Vieques, Jamaica, Saba, St. John, Antigua, Barbuda, and 

 Guadeloupe appear to be the same as those from Cuba, although birds 

 from Porto Rico and Saba average shglitly smaller than those from 

 Cuba; but this may be accidental or due to the smallncss of the series. 

 What this difference is will appear by inspection of the following 

 average measurements of birds from the various islands:

In addition to tlic above, the green heron has records from the 

 West Indian islands of Tortola, Anegada, St. Thomas, Desirade, St. 

 Croix, Virgin Gorda, St. Bartholomew, Montserrat, and Santo Do- 

 mingo, on all of which, presumably, the present race occurs, though 

 actual examination of specimens must finally determine. Through- 

 out its range this subspecies appears to be resident during all the 

 year.

 localities in the West Indies, those with asterisks representing breed-
