birds made by Mr. F. W. Urich in northern Venezuela,’ and numbering 
only 37 species, proved on examination to contain 5 that were apparently 
undescribed, namely: (1) Setophaga verticalis pallidiventris, (2) Chloros- 
pingus (Hemispingus) canipileus, (3) Mecocerculus nigriceps, (4) Meco- 
cerculus uricht, (5) Synallaxts striatipectus. 
Mr. Chapman has also described two new subspecies of Colymbus 
dominicus,? an examination of this group in the light of the material in 
the American Museum of Natural History showing that there are two 
continental forms quite different from true C. domznicus of the West 
Indies. To the South American form (type locality, Chapada, Matto 
Grosso, Brazil) he has given the name C. dominicus brachyrhynchus, in 
allusion to its very small bill, and to the North American form (type 
locality, Lomita Ranch, Lower Rio Grande, Texas) the name C. dominicus 
brachyptera.—J. A. A. 
Chapman on Birds from Greenland.?— The American Museum of Nat- 
ural History has received various collections of birds from Greenland 
during the last few years, in connection with the work of the several Peary 
Expeditions to North Greenland. These collections aggregate about 500 
specimens, and include several especially interesting series of plumages 
of Eiders, Gyrfalcons, Murres, Kittiwakes, etc., which Mr. Chapman in 
the present paper has turned to good use. The number of species repre- 
sented is 48, and many of them are accompanied by the field notes of one 
of the collectors, Mr. J. D. Figgins, who accompanied the Peary Expedi- 
tion of 1896. Unfortunately, the field notes for the Expedition of 1895, 
when one of the most important collections was made, under the super- 
vision of Prof. L. L. Dyche, were unavailable for use in the present 
connection. 
Mr. Chapman gives special attention to the growth and phases of 
plumage in such species as Briinnich’s Murre, the Kittiwake, Fulmar, 
Greenland and King Eiders, and the Gyrfalcons, several of which are 
represented by series illustrating all the changes from the downy chick 
to the fully adult birds. 
Incidentally, Mr. Chapman takes up the question of the relationship of 
Rissa tridactyla to FP. t. pollicaris, and finds that while the development
