The words "C. frontatus nobis" on the stand of the example in 

 the Paris Museum is said to be in Kuhl's handwriting and designates 

 the type; but nowhere is it said to be "type de I'espece," which is 

 almost always written on the stands when any particular specimen 

 is indicated as the type. The example bears no resemblance what- 

 ever to C. CRASSiCEPS, and which Schlegel includes with this species 

 as a synonym of C. variegatus, but is very like the type of C. cirrifer 

 E. Geoff., but has not the long head tufts of that species. The hair 

 on the top of the head is long and stands upright, and is longest on the 

 forehead. The tail is not so bushy as is that of C. cirrifer, and is 

 black with reddish hairs mixed on the basal part. In size this species 

 equals the ordinary Capuchin. 



The type of C. lunatus Kuhl, is now in the Leyden Museum 

 having been obtained in exchange from the Heidelberg Museum. It 

 is a young animal in the brown coat, has a black head, and is evidently 

 in process of change to the adult dress, and cannot be separated specif- 

 ically from the present species. It must however be confessed that 

 the distinctness of C. frontatus is doubtful. Its resemblance to C. 

 cirrifer, (differing chiefly in wanting the head tufts, which may be 

 a mark of age or of season), and our total lack of knowledge of the
