Ten specimens : Bonda, Gaira, Mamatoco, Punto Caiman, and Di- 

 bulla. 



Most of these are unquestionably true noveboracensis, but a few 

 tend toward notabilis. The series sent in by Mr. Smith (including 

 a few additional specimens, not referred to by Dr. Allen, from Ma- 

 matoco and Buritaca) all prove referable to the typical form upon 

 comparison. 



Both of the races of this species are regular winter visitants 

 throughout the lowlands, and even into the highlands up to 4,000 feet, 

 although rare above 1,000 feet. They are almost invariably solitary 

 in their habits, and shy and difficult of approach. They occur here 

 under the same conditions as in the north, being partial to small 

 creeks, mud-puddles along the roads, etc. The earliest fall migration 

 date recorded by Dr. Allen is September 8, 1898, and one was taken 

 by the writer at Gaira as early as September 13, 1913. No specimens 

 of this form happen to be on record later than March 17.

Four specimens : La Tigrera, Don Diego, and Fundacion. 



After careful study of the series collected by Mr. Carriker it seems 

 best to refer these four specimens, bearing dates respectively of 

 April 30, 1913, January 20, 1914, and October 12 and 18, 191 5, to 

 notabilis, with authentic examples of which they agree in their darker 

 upper parts and whiter, less yellowish under surface. The specimen 

 from Chirua mentioned by Mr. Bangs as having been collected by 

 Mr. Brown on February 1, 1899, and which has been examined in 

 this connection, belongs here also. The occurrence of this race here 

 raises an interesting question as to its migration range, which will be 

 discussed more fully in another connection.
