Guaso Nyiro). This form was described by Neumann (Bull. 

 B. 0. C, vol. 23, p. 43, 1909) from Waram, Hawash River, Shoa, 

 Abyssinia, and therefore this name applies to the paler northern 

 birds of Kenya Colony with which I have compared my specimens 

 of Candida. My alexanderi material consists of three males and 

 one female from the Mweru River. 



Parisoma pulpum, sp. nov. 



Type. — No. 94842, Museum of Comparative Zoology, male in worn plumage, 

 from Gunnal, Portugese Guinea. Collected May 28, 1909, by W. J. Ansorge. 



Specific characters. — Similar to Parisoma plumbeum- but with a much larger, 

 more swollen bill; less white on the wing-coverts and remiges; and the feet pale 

 olive-green as opposed to dark brown in P. plumbeum. 



Description of type. — Head, neck, scapulars, interscapulars, back, rump, and 

 upper tail-coverts light neutral gray washed with cinereous, the interscapulars 

 with a brownish tinge; lesser coverts like the scapulars; the middle and greater 

 coverts and the remiges fuscous, the coverts and two outermost primaries ex- 

 ternally edged with grayish buff, the rest of the remiges externally edged with 

 whitish ; the inner webs of all the remiges broadly margined with white ; under 

 wing-coverts whitish; tail dark fuscous, the outermost pair of rectrices white 

 except basally ; the second pair very broadly tipped with white, the outer web 

 being white for its distal two-thirds; the next two pairs tipped with white; the 

 middle two pairs without white tips (but the specimen is badly worn) ; sides of 

 head light neutral gray ; lores blackish, margined above and below with whitish, 

 the whitish extending around the eye; chin whitish, streaked with pale neutral 

 gray; throat, breast, and flanks pale neutral gray; belly and under tail-coverts 

 whitish, tinged with light buff; bill greenish gray, the upper mandible darker 

 than the lower; feet pale olive-green; iris dark brown. The colors of the bill, 

 feet, and iris are taken from the collector's notes on the original label and are 

 not distinguishable in the dried skin, but even in the skin the bill and feet are 

 much lighter than in skins of Parisoma plumbeum. 



Measurements of type. — Wing, 68.5; tail, 66; culmen from base, 15.5; tarsus, 

 18. 



Range. — Known only from the type locality. 



Remarks. — This new tit-babbler closely resembles Parisoma 

 plumbeum, and the specimen in the Museum of Comparative 

 Zoology was labeled as such. The differences in bill and feet are 

 very marked and cannot be considered as pathological in the bird 

 described above. P. plumbeum is said to range from the Cape 

 Colony to Portugese Guinea, but I have seen no specimens from 

 anywhere near the latter country. It may be that specimens 

 from that district will all prove to be pulpum.
