I'xces^ivi'ly fat ; the fat cm its abclomeu and other parts woiglniip; 

 probably lour or live ijoimds. Tlio heart, long and pointed ; weight, 

 4 oz. GO grs. Tiie trachea of moderate .size ; the conneeting mem- 

 brane at the posterior part very thick. Tlie lungs trilobcd ; weight, 

 4 oz. 304 grs. Tiie liver composed of five main lobes ; weight, 11 oz. 

 The spleen long, thin and narrow, with a lateral tongue-like process 

 (as in nearly all of the Marsupiuta) i from the upper end. Jjcngth 

 of spleen, lO-i inches; its average breadth about an inch; it was 

 seated along the left side of the stomach, indiedded in fat. The 

 kidney of a rounded form; weight, 1 oz. 167 grs. The alimentary 

 canal measured only fi feet (i inches. The stomach of moderate size ; 

 its coats very thick, and capable of great distension. The rugae of 

 the lining membrane large and prominent ; the pyloric valve strong 

 and muscular ; the length of empty stomach 8 inches ; the duode- 

 num at its commencement studded with numerous bead-like ])ro- 

 cesses, which emerged into a portion of mucous membrane thickly 

 studded with villi al)out .'} lines in length, as represented in fig. I. 

 These were contimied for nearly four feet ; they resemble much the 

 rumen of the sheep or rein-deer. In the small intestines of the Rhi- 

 noceros, fig. 2, the villi are about ti or 8 lines in length, but far less 

 numerous. 



The ctecum absent. The large intestine measured 12 inches ; the 

 coats thick and the lining membrane plicated longitudinally. The 

 relative weigiit of the viscera as com])ared with that of the body is 

 about as follows : — Liver, 3'=^; spleen, -.^^^ ; kidney, ^^l^^ 5 Jicart,y^-y; 

 lungs, yJ-j ; the blood-corpuscles about jjVo of an inch in diameter.

I have examined the two skeletons of the Thylacinvs at the Mu- 

 seum of the College of Surgeons, a descriijtion of which is given by 

 Professor Owen in the new Osteological (Catalogue (p. .'51 7). The 

 teeth, 4G in number ; incisors, 8 above and G below ; canines, 4 ; 

 molars, 28, 14 in each jaw =iG, Vertebra; : cervical, 7; dorsal, 13; 

 lumbar, ii; sacral, 2; caudal, 23 ; ribs, 13. 



The time does not allow me to dwell on many points of great in- 

 terest resjjecting the anatomy of this animal, but a comparison of the 

 structure of the T/n/lacini'-i with the Dog I am about to describe will 

 not be unprofitable. 



Capk Hlxting Dog (Lycao.x i'ictus. S. Africa). 



This animal died at the Society's Gardens, where it remained for 



some months previous to its death, a few days before which period
