NASUA. 89 



no vesiculse seminales. The penis passes along the belly a considerable 

 way, covered by the common skin, so that the prepuce does not project. 

 There is a bone in the penis which is forked at the end, and is not 

 covered by the glans, but by a thin loose membrane which is celhdar, 

 and can be blown up as in the otter. (Query : Is this always the case 

 where there is no scrotum ?) 



They feed upon fraits and insects. 



The Poto 1 [Cercoleptes caudivolvulus, Illiger], 



Has three grinders like a monkey's ; two sharp-pointed teeth which 

 may be called little canines ; all these are close together in the upper 

 jaw : six incisores, which are close together in the lower jaw 2 . The 

 talons of this animal are like those of a bear. 



The stomach and the whole intestines are as in the bear, racoon, 

 badger, &c. 



The liver is divided into five lobes. The bladder-lobe has two very 

 deep sulci in it, which almost divide it into three ; one for the ligament, 

 the other for the gall-bladder : there are two lobes on the right of this 

 and the lobulus Spigelii. 



The penis lies along the belly, and comes pretty far forwards, and 

 the termination of the prepuce is by a kind of flap or elongation of the 

 lower part ; so that, when this flap is applied to the belly, it covers the 

 orifice of the prepuce. The penis lies pretty far back in this prepuce, 

 and when it is pulled to its full length, it hardly reaches the orifice of 

 the prepuce ; so that in copulation the prepuce must be driven back 

 from over the penis. The testicles are not very prominent ; all these 

 parts are covered with hair, as in the bear, racoon, ferret, coati-mondi. 

 There are no vesiculse seminales. The bone in the penis is very much 

 like that in a racoon. 



The bags by the side of the anus are the same as in the bear.
