Gyrotoma showaltdri (Lea). 



Schizostoma showalteri Lea, Pr. A. N. S. P., 1864, P- 112; Jour. A. N. S. P., 

 VI, 1866, p. 149, pi. 23, fig. 56; Obs., XI, 1866, p. 105, pi. 23, 56. 

 This is a different species from that described by Lea under the same 

 name in i860, which proved to be a synonym of G. cariniferum (Anth). 

 The name being preoccupied, this species will have to be re-named, if it 

 should prove to be a valid one on a revision of the genus.

Genus ANCULOSA Say, 1821. 



Pilsbry has recently come to the conclusion (105, p. 109) that Leptoxis 

 Raf. should be preferred for this genus. In my paper on Pleiirocera (161, 

 p. i) I reluctantly acquiesced in his conclusion on the ground that the ques- 

 tion was zoological rather than one of Code construction. Since that time 

 I have again gone carefully over the ground and have become satisfied that, 

 if all incompetent evidence is eliminated, there is not sufficient grounds to 

 justify the change. I have therefore retained Say's well known name for the 

 genus.
