face ; in the males it is in the opposite direction. The posterior ex- 

 tremity of the body of the female is subulate ; in the male it is more 

 abrupt, but ends in an exceedingly fine and short mucro. The penis, 

 which appeared to be single in some, double in other specimens, was 

 commonly protruded. The males and females are very nearly of the 

 same length, viz. 4-| lines ; their colour is white. The oeso])hagus is 

 long, straight, and nearly of the same diameter until it joins the 

 stomach, where it increases in size ; the stomach is globular or pyra- 

 midal. The intestine is straight, diminishes slightly in diameter pos- 

 teriorly ; it is surrounded by the convolutions of the ovary, which are 

 long ; in the male it is surrounded by a shorter spermatic tube. 



* The Ascaris acuminata is very common in the small intestine of 

 the frog (Rana temporaria) : I have found a species in the intestinal 

 canal of the common water-newt (Triton j)alustris) which appears to 

 be identical with it. The longest measure 8 lines ; they are veiy 

 slender, colour white, equally attenuated at each extremity. The 

 posterior extremity is acuminate, the mucro long and somewhat tri- 

 angular ; the head is obtuse, the tubercles of the mouth distinct. 



t The Ascaris marginata is probably the Asc. Canis of Turton's 

 ' British Fauna ;' it is very common in the small intestine of the dog.
