LASIOPYCA 309 



Genl. Char. Like L. leucampyx, but top of head, shoulders, and 

 nape of neck speckled with gray. 



Color. Brownish white band on forehead speckled with black ; 

 top of head and temples black sparsely speckled with gray ; sides of 

 head black speckled with buff ; upper part of back black minutely 

 speckled with white ; rest of upper parts and sides profusely speckled 

 with cream buff ; inner and outer sides of arms, and hands jet black ; 

 legs and feet black, but tinged with brown and slightly speckled on 

 inner side of thighs near body ; chest and under parts, and inner side 

 of legs sooty gray ; hair of tail all gone except a little about midway 

 the length, which is black. Ex type British Museum. 



Measurements. Skull of L. tluto in the British Museum No. SO. 

 7. 7. 9. not the type ; total length, 100.6 ; occipito-nasal length, 86.2 ;

The type does not seem to be a fully adult individual, the coloring 

 of the band on forehead, the under parts and legs are brownish black 

 and sooty instead of jet black, appearing to indicate immaturity. The 

 type came from Angola. Fortunately there is an adult Lasiopyga 

 from Dando, North Angola, which is doubtless the same species as 

 PLUTO, and which presents us with adult pelage. It may be described 

 as follows : band on forehead, narrow at ends and broad in the center, 

 white with a row of speckled black and white hairs at the base of the 

 band in front ; sides of head and throat black speckled with white ; 

 top of head and temples black; back of head and neck speckled black 

 and white, overlaid by long jet black hairs, these last extending down 

 to between the shoulders; upper part of body and flanks profusely 

 speckled black and white, the latter here greatly predominating ; inner 

 and outer side of arms and legs, hands, feet, and entire under parts 

 below throat jet black ; chin and upper part of throat sooty gray ; tail, 

 basal half black speckled with white, apical half black. 



Mr. Pocock in his review, (1. c.) gives the character to separate 

 L. PLUTO from L. stuhlmanni as the "speckling of the summit of the 

 head with the nape and shoulders," but the specimen from Angola, 

 which I consider the adult pluto has the summit of the head jet black, 

 so it would seem that the speckling on the head was due to immaturity. 

 L. PLUTo's claims for being a distinct species must therefore rest on 

 some other differences to separate it from L. stuhlmanni, and these
