384 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. xxxvi. 



As the anatomy of the schivelyce forms was unknown, we were 

 anxious to dissect specimens. Doctor Dall has very kindly sent ns a 

 specimen of hahamensis collected in the Bahamas by Mr. Riley, It 

 is only half the size of the types, and unusually pale in color. Un- 

 fortunately, the generative organs were not developed, but fig. 8 

 represents the under surface, showing the projecting foot, and fig. 7 

 one of the alimentary canal and liver. 



On the whole, it seems not unlikely that the Bahama and Bermuda 

 slugs have been introduced from Mexico, and are in fact V. moreleti. 

 This can not be demonstrated, however, until much more material is 

 obtained, both of the Mexican and insular forms. The species of 

 P'lorida, Cuba, and Jamaica, so far as known, are not of the moreletl 

 type. 



The measurements of the specimen of T", i^clt'/rclyn- hahamens'ts 

 examined by us are as follows: Length, 38 nun.; Ijreadth, IG; breadth 

 of sole, 5 ; female orifice from the sole, 2.5 ; from margin, 3,5 ; from 

 anterior end, 21, The female orifice is distant from the head 55 

 per cent of the total length.
