through the forest like a rocket. Still-hunting is the only possible 

 way to secure specimens. 



Three eggs of this species, found by Mr. Smith's collector "' on the 

 ground " at Valparaiso, May 26, are of the spheroidal shape usual in 

 this family, very glossy in texture, and deep bluish glaucous in color. 

 They measure 59 X 46-

Crypturornis soui is a species which varies immensely in various 

 parts of its extensive range, no less than eleven geographical races 

 having been described up to date. Of these C. soui mustelinus, pro- 

 posed for the Santa Marta bird by Mr. Bangs, is one of the best 

 marked. The females of C. soui soui, C. soui mustelinus and C. soui 

 cauccc are all very much alike so far as the colors of the under parts 

 are concerned, but they can be separated by the color of the pileum, 

 which is brown in mustelinus, and grayish or dusky in the other two 

 forms. The upper parts in general also average slightly paler. Males 

 of mustelinus are paler, more buffy, less rufescent brown both above 

 and below than the same sex of either soui or cauccc. A small series 

 from northern Venezuela indicates that the range of mustelinus ex- 

 tends to that section also. 



This little tinamou is not a rare bird at all, but is next to impossible
