" With respect to the organs of generation in the malė, the testas 

 lay obliąuely upon ihe body of the pubis outside the abdomen, but, as 

 is common to the aąiiatic Mammalia, without niaking any projection 

 externally ; the communicatioti betvveen the tunka vaginalis and ab- 

 domen was hirge enough to allovv these glands to be pushed back iuto 

 the latter cavity. Tliere weie no vesiculce seminales, and only a very 

 small prostate. The penis has a pointed glans, and a bone about 

 half an inch long, of a flattened form with thicker extiemities ; into 

 this bone are inserted two retracfor and depressor museles, vvhich arise 

 from the common anterior tendon of the sphincter ani. From the 

 prepuce to the aniis measured 5 inches, the penis being inclosed in a 

 sheath and making no projection externally. 



"The museles of the fore and hind-flippers \vere dissected : in the 

 latter are tvvo peculiar museles for expanding the web of the foot, 

 whlch have been described in detail by Carus. The extent of origin 

 of the pectoralis major is increased by a cartilaginous process, 3 

 inches long, continued from the mannbrium, or first bone of the slernum. 

 This circumstance involuntarily reminds one of the Mole, vvhere a 

 similar structure exists, also in connexion with vigorous rotatory 

 movement of the anterior extremity -. but in that animal the structure 

 is by so much the more marked, as progressive motion is attended 

 with the displacement of denser and more resisting matter ; it may 

 be said, indeed, to swim in the earth.

 animals.

 brought forth at the Society's Gardens on the 3rd of September, and
