birds." I have examined also llie large scries of this species in the 

 collection of the Field Museum, which confirms in general the above 

 observations. Specimens from the Caicos Islands constantly have 

 longer bills than the average, while those from Great Bahama Island, 

 at the other extremity of the group, seem to have bills shorter even 

 than New Providence birds. I am unable to discover any other con- 

 stant ditTerences, however, that would justify formal subdivision of 

 the species, particularly as the vast majority of Bahaman specimens 

 could not be assigned to either form. 



An individual in full ju\enal dress was taken at Spencer's Point, 

 Abaco, on May 5. 



77. Agelaius phceniceus bryanti Ridgway. 



Eleven specimens: New Providence (Blue Hills); Andros (Stan- 

 iard Creek); Abaco (Sand Bank, Spencer's Point). 



The seven adult males included in this series have the following 

 average measurements: wing, 116 mm.; tail, 87; culmen, 24.5. Four 

 adult males from peninsular Florida average: wing, 116; tail, 92; 

 culmen, 24. Neither comparison nor actual measurement discloses any 

 appreciable average difTerence in the size and shape of the bill between 

 these two series, and I fail to see how the males of floridanus and 

 bryanti can be distinguished from each other. In the case of the 

 females, however, the differences are sufificiently evident, and may 

 be accepted as being of subspecific value. Bahaman females are much 

 whiter below than those from Florida, and seldom show traces of the 

 pinkish suffusion on the throat which is often so conspicuous a feature 

 in the latter. This statement is based mainly on a study of the large 

 series of this subspecies in the collection of the Field Museum, there 

 being only two females in the present lot. Two males from Abaco 

 are in first nuptial plumage.

"Iris hazel" (adult male). 



Dividing this series into four sets, according to sex and age, there 

 are three adult males, four adult females, three immature males, three 

 immature females — the immature birds being of course in first nuptial 

 plumage. Two of the adult females are indistinguishable (except 

 as regards the under tail-coverts, mentioned below) from the adult 

 males, being fully as bright so far as I can see, while the other two
