298 LASIOPYCA 



This is a peculiarly colored monkey, showing an affinity to mem- 

 bers of various groups, and yet seems distinct from them all. Mr. 

 Pocock in his paper, (1. c.) has made L. thomasi (Matschie), a sub- 

 species of L. l'hoesti, but this does not seem to be the proper place 

 for that species, as Matschie's type is very like L. preussi but paler on 

 the back, and the tail is lighter; the limbs, however, and shoulders 

 are black as in L. l'hoesti.

Type locality. Northern Nigeria, (Bakie). Type in British Mu-

 over temples black, rather long, directed backwards passing over the 

 ears ; long hairs on cheeks directed backwards under and behind ears,

 yellow speckles ; entire upper parts of body grayish black minutely

 also on legs to ankles ; feet black ; chin, throat, chest, anal region, inner

The type is a young animal, but it is quite different in appearance 

 from any of the known species, so different in fact, I hardly know 

 where to place it, for like L. l'hoesti it does not seem to have any
