The ceecum absent. The large intestine measured 12 inches ;. the 
coats thick and the linmg membrane plicated longitudinally. The 
relative weight of the viscera as compared with that of the body is 
about as follows :—Liver, 3,; spleen, z+, ; kidney, 335; heart, 737; 
lungs, ;4;; the blood-corpuscles about 7255 of an inch in diameter.

I have examined the two skeletons of the Thylacinus at the Mu- 
seum of the College of Surgeons, a description of which is given by 
Professor Owen in the new Osteological Catalogue (p. 347). The 
teeth, 46 in number ; incisors, 8 above and 6 below ; canines, 4 ; 
molars, 28, 14 in each jaw =46. Vertebre : cervical, 7; dorsal, 13; 
lumbar, 5; sacral, 2; caudal, 23; ribs, 13. 
The time does not allow me to dwell on many points of great in- 
terest respecting the anatomy of this animal, but a comparison of the 
structure of the Thylacinus with fhe Dog I am about to describe will 
not be unprofitable. y 
Care Huntine Doe (Lycaon rrcrus. 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 
it had several convulsive fits. I could not examine the brain; but 
Mr. Ward, who stuffed the animal, told me that a large quantity of 
serum escaped from the cranium, so that probably death was occa- 
sioned by inflammation of the brain and effusion of fluid. 
In Cuvier’s ‘ Animal Kingdom,’ 1849, by Carpenter, p. 91, is the 
following note :—‘ This remarkable species is dog-like, but certainly 
not a Canis; its form and colouring (and, there is reason to suspect, 
its internal conformation) are rather those of a hyzna, and it is 
known to copulate in the manner of those animals, and not in the 
peculiar manner of the dogs and foxes. Even its dentition is the 
same as that elsewhere found (with one other exception, Proteles) 
throughout the group to which we conceive the hyzenas to belong, 
the dental system of which latter appears to be modified in accord- 
ance with their much increased and prodigious strength of the jaw.” 
This dog weighed about 50 Ibs. ; it measured 3 feet 1 inch from 
nose to root of tail; tail, 13 inches; height to the back behind neck, 
2 feet 3 inches; fore-leg, 164 inches ; ribs, 13. Teeth: incisors, 6 
in each jaw, 12; canines, 4; molars, 10 above and 12 below, =38. 
The age of the apimal about 25 years. Heart of a rounded form ; 
weight 8 oz.; the parietes of the left ventricle 10 lines in thickness, of
