iieartj and aprolongationon either side becomingthinner and thin- 

 ner, until at the base was some vestige of raembrane. The heart 

 was contained in this cavity, but its vessels, both pulmonary and 

 arterial, were apparently lengthened in order to reach the lungs. 

 The lungs, pressed out of their place by this unnatural body, were 

 diminished in size ; the substance softened, half pultaceous, and, 

 wheu sąueezed, a purulent raatter escaped. There were also nu- 

 merous minute tubercies in the substance of the lungs. The animai 

 had vvasted almost to a skeleton.' 



" We may therefore regard the complaint of the Kinkajoii as 

 being a long-continued strumous disease, in which some of the tu- 

 berculous deposits, instead of suppurating, had become partially or- 

 ganized, and the cellular septa rendered ligamentous. 



" I conclude with afevv observations on the aflSnities of the genus 

 Cercoleptes, as they are elucidated by the preceding anatomical ac- 

 count. 



" Besides the difFerences of outvvard form vvhich the Kinkajou 

 presents, as compared with the Lemur, in the shorter muzzle, the ab- 

 sence of the hinder thumb, and the presence of the prehensile tail, 

 as \vell as in the quality of the hair and the dentition, the following 

 important discrepancies occur in the internai anatomy of these two 

 genera : 



" In Lemur the intestinal canal is above six times the length of 

 the animal's body ; in the Kinkajou it is scarcely five. In Lemur 

 it is also complicated by a ccECum of considerable length (raeasur- 

 ing 15 inches in the ruffed Lemur, according to Mr. Mai'tin, and 

 vvhich I found of 7į inches in length in a Lemur nigrifrons). The 

 cc//o« also in ūie Lemures,\& largely developed, (measuring upvvards 

 of 2 feet, ) and is sacculated at its commencement. In the Kin- 

 kajou the large intestiue, as in the Raccoon, is separated from the 

 small by a slight internai circular projection of the mucous mcm- 

 brane, and measures only 6 inches in length. The stomach is also 

 nanower at the pyloric end, and more bent upon itself than in 

 Lemur, 



" With respect to the digestive glands, there are no matcrial dif- 

 ferenccs. In both animals the liver is much subdivided, and the 

 spleen is large. The kidneys are of a simple exterior in the Kin- 

 kajou, as in the Raccoon ; not lobulated, as in the true Ursi: in 

 this respect they resemble Lemur, but the form is so usual as not to 

 authorize any deduction from it. In the generative organs, how- 

 ever, the Cercoleptes recedes from the Quadru7nanous type further 

 than the Lemur, in the extent to which the uterus is divided, and 

 the con3equently greater length of the cornua, and Fallopian tubes. 

 Its nearer affinity to Procyon is also manifested in the disposition of 

 the serous capsule about the ovarium, vvhich leaves only a small 

 orifice sufficient to admit the end of a probe ; while, in Lemur, the 

 ovaria are situated, likę those of the Q.uadrumana, almost as in the 

 human subject. 



" In the osseous systemit may be noticedthat the Cercoleptes de-
