retained this form after macerating in water several days and then 

 inflating. The length of this part of the intestine, from the ileo-csecal 

 valve to the anus, was 18 inches. 



The liver presented three very distinct lobes : the left one was en- 

 tire ; the middle cleft into three by two fissures on its under surface, 

 in one of which (that most to the right) the gall-bladder was placed ; 

 the right lobe was entire, but on its under surface was placed the 

 lobulus Spigelii. 



The gall-bladder was pyriform ; the duct, 3 lines in length, join- 

 ing the hepatic duct, formed the common gall-duct, which was half 

 an inch long and entered the duodenum one inch from the pylorus. 



The spleen was long, narrow and flattened, half an inch wide at the 

 broadest part, and 2^ inches in length. 



The kidneys, simple, large and oval, were 1 inch long and 8 lines 

 broad ; the right one situated nearly the whole length of the kidney 

 higher than the left. 



The penis was 3 inches in length, containing a bone 1 1 lines long. 

 The skin of the glans covered with minute spines or tubercles, which, 

 when examined microscopically, were found to be tooth-like bodies, 

 most having two points, some one, others three or more, all directed 

 backwards. 



The testes were oval, 8 lines long, 5 broad. 



The vesiculse seminales consisted of two large simple culs-de-sac, 

 7 lines in length. 



On opening the thorax the left lung was found to have two lobes, 

 the right four. 



The heart presented nothing unusual. From the arch of the aorta 

 two large vessels arose, the first giving rise to the innominate and left 

 carotid ; the second being the left subclavian. 



On examining the brachial and femoral arteries, no division into 

 smaller trunks, forming a rete mirabile, as is observed in several 

 animals belonging to this family, was discovered. The brachial artery 

 perforated the humerus near its lower extremity. 



The tongue was long and narrow, 2| inches long from the root of 

 the epiglottis to the tip, and 5 lines broad. Its dorsal surface was 

 covered with small papillae, and at the posterior part were three large 

 or circumvallated papillae, arranged as the points of the letter V. On 

 the under surface is a curious body, 7 lines long and 3 wide, the tip 

 of which is free, flat and pectinated, the rest free at the sides and at- 

 tached in the middle. From the form, position and size of this singular 

 organ, one cannot help conjecturing that the pectinated end may act 

 as a brush to free the inferior incisor teeth from adherent particles of 

 the insect food on which the animal subsists. 



The submaxillary and parotid glands were very large, particularly 

 the former. 



The masseter and temporal muscles were largely developed, and 

 the whole muscles of the upper extremity very powerful. 



The cerebral hemispheres were large, and extending some way 

 back over the cerebellum, but their surface was remarkably smooth
