ZOOLOGICAL. 



Nemertes, Mag. Zool. and Bot. i. p. 529. — Accidentally turn- 

 ing over the " Edinburgh Journal of Natural and Geographical 

 Science" for June 1831;, my attention was caught by some observa- 

 tions on Planaria and allied genera by M. Ant. Duges. From 

 these it is evident that Duges' genus Prosloma is the same as that 

 I have named Nemertes. He considers the organ described by me 

 as a stomach to be the mouth ; and the groups of points on each 

 side of it he thinks are probably intended to retain the prey on 

 which the worms feed. The ovarian pouches, according to him, 

 open externally along the sides, and are capable of being protruded 

 by compression. These are points which we shall soon, perhaps^ 

 have an opportunity of reconsidering when describing some addi- 

 tional species of the genus. It is to be remarked, that all those 

 described by Duges appear to be natives of fresh water. — G. J.
