PLEUROCERID.^. 



It has been suggested that the family name should be properly Pleuro- 

 cerahdcB. But Stejneger (Herpetology of Japan, Bull. 58, U. S. Nat. Mus 

 p. 24) m a similar case has decided that the change is not necessary 



The errata given by Tryon on p. '427 of his "Strepomatid^" are not in- 

 cluded m his index and have, therefore, been noted under the several species 

 as they are likely to be overlooked. 



Pilsbry (Pilsbry and Rhoads, iii, p. 496) has proposed the following re- 

 arrangement of this family : 



Genus lO Lea. 



Type Fusiis Uuvialis Say. 



Genus LITHASIA Haldeman. 



Type Anculosa (Lithasia) geniculata Hald. 



Section ANGITREMA Haldeman. 



Type Melania annigera Say. 



Genus PLEUROCERA Rafinesque. 

 Type ? 



Section STREPHOBASIS Lea. 

 Types S. spillmani, cornea and clarkii Lea {2i\\ = plena Anth.) 



Genus ELIMIA H. and A. Adams. 



Type Ayfelania acntocarinata hea.. 



Genus GYROTOMA Shuttleworth. 



Genus ANCULOSA Say. 



Dr. Pilsbry has more recently decided that Goniobasis should be restored 

 to its former position as a generic term, on the ground that EUmia was a 

 composite group. 



. It will be noticed that no mention is made of Bnrycalon in this arrange- 

 ment. While, as Tryon remarks (134, p. 341), the genus as aggregated by 

 him is made up of incongruous elements and upon a revision of the family 

 will no doubt be dismembered, the typical group, of which anthonyi and 

 crassa are leading terms form a very distinct group, which seems entitled 

 to recognition. 



Genus LITHASIA Haldeman, 1840.
