698 STERNA FTTLIGINOSA, SOOTY TERN. 



scarcely two-tenths of an iuch long. Rectum extremely sliort. Cloaca Iprge and 

 globular. Kidneys only divided into three or four lobes. 



This subgenus iu many respects is allied to Anous, apparently connectieg the two sec- 

 tions Sternal and AnoHa-, though uuquestiouably belonging to the former. Its essential 

 features lie in the shape of the bill, position of the nostrils, «fcc. In pattern of color- 

 ation there is a considerable deviation from the ordinary type. There are few notice- 

 able anatomic-il points, the chief being the sleuderuess of the trachea, weaknes of the 

 lower larynx, and narrowness of the proventricular zone. 



Three names proposed for the genus are by the same author and bear the same date. 

 In this instance it seems to be a matter of choice which to adopt; and, although Huli- 

 2)hinu is instituted several pages after Onyclwprion and Flanetis, I prefer to adopt it, as 

 its type is the well-known S.fidif/inosa, and as it is the most euphonious. 



Until recently but a single species of the section was known to inhabit North Amer- 

 ica. Mr. G. N. Lawrence introduced the Central American anosthcvta {''discolor") into 

 our fauna, by virtue of specimens in his cabinet from Mr. Audubon's collection, labeled 

 as having been taken iu Florida. It appears to be a common bird of the Central 

 American coast and islands. 



The following analytical table will serve to distinguish the two North American 

 species of the section — H. luiiuta, Peale, not an inhabitant of North America, being in- 

 troduced for further comparison: 



Common characters. — Bill and feet black. Under i>arts and a frontal lunula white. 



I. Back like crown. 



1. Above, deep brownish-black fidiginosa. 



II. Back not like crown ; crown black. 



2. Back deep suioky-gray ava'stheta. 



:i. Back light pearl-gray lanata.
