LASIOPYCA 381 



palatal length, 35.6; length of upper canines, 14.8; length of mandible, 

 68; length of lower molar series, 29.6. 



Since Linnaeus described the present species, the name which he 

 gave to it, diana, has been conferred upon the wrong animal by nearly 

 all writers. Dr. Jentink, (1. c.) however, in his paper corrected the 

 error that existed for so long a time, and proved that true diana was 

 the monkey with a short beard, black at the base and white at the ends, 

 that it had tufted ears, and the inner side of the thighs, and anal region 

 bright bay; the one named L. roloway, heretofore called diana by 

 many mammalogists, is the monkey with a long pure white beard, and 

 the inner side of thighs white or pale orange, and the ears without 

 tufts.
