iJn the Bulletin of the British Ornithologists' Club, no. xxvii. May 31, 1895 (Ibis, 

 1895, 384), Mr. Rothschild mentions a S. [permopMlopsis'] scMstaceus (Temminck). 

 This I have been unable to look up, but if the bird in question is congeneric with 

 SpermopMla scMstacea Lawrence the latter would have to be renamed.

I cannot refer this bird to »S'. g. grisea, since, upon comparing it with twelve adult 

 males of the latter, including five from Bogota, it seems very distinct; apart from its 

 very much darker coloration, conspicuous white spot on each side of the lower throat, 

 and abrupt definition of the white abdominal area against the deep slate-color of 

 sides and chest, the wing is much longer, the tail decidedly shorter, the tarsus much 

 shorter, and the bill not only smaller but quite different in shape, the culmen being 

 much less strongly convex and the maxilla conspicuously shallower. 



Adult males of the two forms examined average in measurements as follows:
