projecting forwards, two on each side : they appeared to be four of 

 the horny papilla of the glans elongated and developed, for these 

 papilla surrounded their base and were there rather larger than lower 

 down on the glans. 



" I found, as in Capromys and Coypus, a decided decussation of the 

 pubic pillars of the recti abdominis muscles. 



" The testes, of an oval shape, were within the abdomen, as high 

 as the top of the haunch bones ; — the epididymis formed a knot at 

 the end of the testis, adhering closely to it, whence it sent a tube 

 along the testis to the opposite or small end; arriving there it 

 formed a knotted congeries of fine convolutions, from which emerged 

 the vas deferens. To this congeries there proceeded from the abdo- 

 minal ring (which was imperforate) a muscular, tubular sac, or ore- 

 master, the fibres of which embraced it. The ring being imperforate, 

 the testis, I imagine, never passes externally into the groin. 



" The vas deferens emerging from this congeries of tubes, turned 

 round, crossed the smfJl end of the testis, and descended over the 

 vesicula seminalis of its own side. 



"The vesicula seminales were 1 inch in length, slender and con- 

 voluted. 



" The prostate gland was double ; Cowper's glands were of the 

 size of peas, and round. The membranous part of the urethra was 

 4 of an inch in length. 



" The fauces were not funnel-shaped, but constricted by a lateral 

 pillar rising up from the base of the tongue on each side to the pa- 

 late, which wants tonsils and velum pendulum : the aperture thus 

 formed just admitted the top of a pencil. The nares opened 2 or 3 

 lines beyond this constricted portion just above the rima glottidis ; 

 they were not therefore visible, until the fauces were ftdrly laid 

 open. The contraction of the /a«ces is less decided than in the 

 Coypus."
