LOXIGILLA VIOLACEA. 



A specimen of this species from the Bahamas differs from Jamaican 

 examples in larger bill and feet and much more intensely black plum- 

 age; the chestnut- red of the throat, etc., being also deeper and richer. 

 These differences being probably geographical, the Bahaman form seems 

 entitled to a distinctive name, and I therefore propose that of haha- 

 mensis. 



The characters of the two races may be defined as follows: — 



a. violacea. — Plumage of the body more or less decidedly slaty posteriorly ; lining of 

 the wing white. Throat, eyebrow, and crissum bright cinnamon-rufous. Wing, 

 3.00-3.30; tail, 2.90-3.20; bill, from nostril, .40-.45; depth of bill, .40-.48; tar- 

 sus, .70-.80 ; middle toe, .55-.60. Hah. — Jamaica. 



;3. iaiiamensis. — Plumage of the body lustrous black posteriorly; lining of the wing 

 dark grayish. Throat, eyebrow, and crissum rich purplish rufous. Wing, 3.25 ; 

 tail, 2.95; bill, from culmeu, .45; depth of bill, ..50; tarsus, .85; middle toe, .65.

ANAS ABERTI (Ridg., MS.).

 streaks. Head, neck, and lower parts streaked, the streaks finest ou

 with irregular indentations and occasional bars of the same. Lesser 

 wing-coverts brownish-slate, bordered with dull earthy-brown ; middle 

 coverts with their exposed portion velvety-black, forming a distinct bar. 

 Secondaries widely tipped with pure white (forming a conspicuous band 

 about .35 of an inch wide), this preceded by a velvety-black bar of 

 about equal width, the basal half or more (of the exposed portion) con- 

 sisting of a metallic speculum of dark grass-green, varying to blue and 

 violet in certain lights. Tertials opaque velvety -black exteriorly, the
