Tryon (130, p. 374) says that this is "doubtless" V. lineata Val. (con-

 so far south. It is more probable that it is either georgianus (Lea) or 

 waltonii Try. If the latter, it would have priority. Tryon (131, p. 197) 

 suggests that the Florida contectoides listed by Binney are "perhaps" his 

 zvaltonii. 



A-'iviPARus HALEANus (Lea). 



This is apparently a valid species as stated by Tryon. It also occurs 

 in Itchaway-Notchway Creek, Baker Co., Ga., and fossil in a peat bed at 

 Lake PanasofFkee, Fla. 



Viviparus intertextus (Say). 



Hannibal (53, p. 193) has proposed a new subgenus, Callina, having this 

 species as the type. The distinction seems to be based on the rounded 

 whorls and perforate shell of this species as compared with the imperforate 

 shell and siibcarinate body-whorl of typical Viviparus. But as the embryonic
