PleurocEra biT/T^niatum (Conrad). 



According to Pilsbry (iii, p. 499) Strrpliobasis clarkii Lea is not c> 

 synonym of this species, but of plena Anth. 



Peeurocera eyonii (Lea). 



Strephohasis lyonii Lea, Jour. A. N. S. P., VL 1866, p. 151, pi. 23, fig. 65; 

 Obs., XI, 1866, p. 107, pi. 23, fig. 65. 



The figure given by Tryon (134, p. 46, fig. 93) for this species is erron- 

 eous and is that of Bitryccclon nmhonatnni (loc. cit. fig. 658). 



If Pleurocera (Trypanostoina) lyonii Leo is a valid species, it has prior- 

 ity over this one, which, if also a valid species, will have to have a new name. 

 But in the present chaotic state of our knowledge of the family, it does not 

 seem advisable to propose one until the double question of synonymy is 

 definitely settled. 



PeurocEra plenum (Anthony). 



Includes clurkii (Lea), corneum (Lea) and spillmani (Lea) according 

 to Pilsbry (iii, p. 499) and P. glandiilum (Anth.). 



"Strepitorasis" hartmaniana Lea mss. 



Is listed by Lewis (1. c.) among the probable synonyms of P. airtiiin 

 (Hald.). It does not appear to have ever been described.
