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

 the homy papilta of the glans elongated and developed, for these 

 papillte surrounded their base and were there rather larger than lower 

 down on the glans. 



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

 pubic pillars of the recti abdominis museles. 



" The testes, of an oval shape, ■were -vvithin the abdomen, as high 

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

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

 along the tęstis 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 (\vhich was imperforate) a muscular, tubular sac, or cre- 

 master, the fibras of -nhich embraced it. The ring being imperforate, 

 the tęstis, I imagine, never passes extemally into the groin. 



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

 round, crossed the small end of the tęstis, and descended over the 

 vesicula seminalis of its own side. 



"The vesiculee 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 /aj/ces \vere 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 \vants 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 abeve the rimą glottidis ; 

 they Avere not therefore visible, until the fauces \vere fairly laid 

 open. The contraction of the fauces is less decided than in the 

 Coypris.".
