abundant in the more humid portions. Open woodland and shrubbery 

 are its favorite haunts, instead of the heavy forest.

This plainly colored hummingbird is a littoral form, invai4ing the 

 . Santa Marta region from Venezuela. The exact locality where Simons 

 took his specimens is not stated, but was probably some point at the 

 foot of the south slope of the Sierra Nevada. It is not uncommon at 

 Rio Hacha in the thorny scrub, and is doubtless confined in this region 

 to the Goajira Peninsula and the drier portions of the country south 

 of the Sierra Nevada.

Messrs. Hellmayr and von Seilern have shown that the Trochilus 

 buffonii of Lesson was based on the Bogota form, in which the tail is 

 wholly bluish black. The bird from the coast region of Venezuela and 

 Colombia, in which the middle rectrices are glossed with dark green 

 or bronzy, they recognize as subspecifically distinct under the name 

 ceneicauda. With this conclusion we agree, after examining, in addi- 

 tion to the above, an ample series from Venezuela, although there is, 

 to be sure, considerable individual variation. Although Mr. Ridgway 

 intimates that Santa Marta examples differ from those from Vene-
