eggs- — so far that I was able to save only one. It is rather short 

 ovate measuring 18.25 x 13.75 mm. The color and markings are 

 similar to those described above. The markings are massed chiefly 

 in a circle about the larger end. 



A male in juvenal plumage taken at Caicara, June 8, 1905, (No. 

 13,844 Cherrie Coll.), is dark brown (nearly a clove brown) above, 

 wings and tail darker. Feathers of the back and head narrowly 

 tipped with buffy brownish. Wing-coverts rather broadly tipped 

 and tertials tipped and edged on the outer webs, with the same color. 

 Throat and upper breast brownish gray, slightly mottled by buflfy 

 tips to the feathers ; remaining under parts including under surface 

 of the wing a primrose yellow. Eye grayish brown ; bill and feet 

 blackish. 



In adult fresh specimens the eye is vandyke brown or seal brown ; 

 bill is black or blackish ; feet slate black. 



In the American Museum is a single specimen from Maripa on 

 the Caura River (Klages Coll.).

A young bird 24 to 48 hours old had the skin of the back jet

The nesting season in the middle Orinoco region occurs during 

 April and May. Some six or eight nests of this species have come 

 under my observation, and in each case they have been in trees in 

 which other species of birds were nesting. Two of the nests exam- 

 ined, taken at Quiribana de Caicara April 8th and 14th, 1898, 



'Mr. Ridgway in characterizing the genus Legatus (Birds of North and Middle America, IV. 1907. 

 438"), says: — tarsus "typically exaspidean. " However, a careful examination of the specimens in the series 

 in this Museum indicates that the tarsus is far from typically exaspidean; rather it is pycnaspidean, or per- 

 haps it would be better described as quasi taxaspidean. The acrotarsium extends across the outer side of 

 tarsus, but apparently does not overlap the posterior edge at any point. The broad planter space between 

 the edges of the acrotarsium is occupied on the posterior edge by three series of small roundish scutella or 

 granules between which and the inner edge of the acrotarsium is a narrow area of non-scutellate integument.
