Mr. Vigors and Dr. Ilorsfield 



a distinct species from 5^. nasica. It has been suggested to us that they 

 may be the young of that animal ; but we have no facts by which wo can 

 determine this point ; and with so great a disproportion between the 

 facial angles of both animals, we cannot allow ourselves to come to the 

 conclusion that they are the same, without some stronger grounds than 

 mere conjecture. We shall give the profiles of both these creatures; and 

 thus pointing out the chief differences between them, we consider that 

 we shall add as important a fact to science, even should they prove to be 

 the young and adult of the same species, by demonstrating the change 

 that takes place in the animal at different stages of life, as if these differ- 

 ences, according to our own supposition, should be found to be specifick. 



J^as. recurvus. 



J^''as. nasicus. 



It is to be observed that these animals were preserved in spirit, and 

 consequently were not subject to the same contraction of the soft parts of 

 the nose as might have taken place in dried skins. 



Nasalis recurvus. 



KcLS. capite, collo, hnmeris, femoribusque supra rujis; abdomine 

 paJlidiore; dorso medio ruf escenti-griseo ; br achiis femoribusque inter nis, 

 dorso imo, cauddque supra griseis; caudu infra alhidd. 



The general colour and markings of this animal correspond with 

 those of JNa*. nasicus. The skin of the face however is reddish, where 

 in the other species it is black. The beard is very prominent. In Xas. 

 nasicus the hairs on the chin scarcely assume the appearance of a beard.
