adult females from coast of Alabama: wing, 274.3 (270-280) ; tail, 162.7 

 (155-168); exposed culmen,45.8 (45.5-46); depth of bill at nostrils, 16.2 

 (16-16.5); tarsus, 57 (.54-59); middle toe, 33 (32-34). 



iJemar-is.— This new race of the common crow seems to be fully as well 

 characterized as the otlier recognized subspecies. Although the bird is 

 nearest to C. h. hesperis in size, its range apparently is separated from 

 the range of hesperis by a strip of country in central Texas in which no 

 crows breed. Specimens examined from east Texas are apparently inter- 

 mediate between brachyrhynchos and paulus. A series of 9 breeding 

 birds from the District of Columbia and vicinity are also somewhat inter- 

 mediate, but much nearer to paulus. This form shows no approach to 

 pascuus, the resident bird of south Florida, which has much larger bill 

 and feet. A breeding male from Christchurch Parish, South Carolina, is 

 typical paulus and a breeding female from Mt. Carmel, Illinois, is 

 apparently nearest to this form. 



Since Corvus brachyrhynchos has now been separated into five races, it 

 seems desirable to fix the type locality of the original form. Brehm, in 

 describing the species,* attributes it to North America, without mention 

 of a definite locality. The measurements given by him (length, 19}4 

 inches; tail, SJ^ inches; bill 23 lines) indicate a large bird and there is 

 every probability that his specimen came from northeastern America. 

 The large form is known to occur throughout New England and the type 

 locality is hereby fixed at vicinity of Boston, Massachusetts.
