This shell is certainly more closely allied 
to Dentelaria (which it resembles in color and 
texture) than to Cepolis, Monfort, as stated by 
Pfeiffer.

specimens at Columbus, O., and two good 
ones yesterday in drift on Tuscarawas River.

Editor Conchologists’ Exchange: 
Sir: In the sixth number of The Conchol- 
ogists’ Exchange, 1886, p. 26, Mr. Harry A. 
Pilsbry, has remarked that several of the names 
I proposed for some groups of Helices were 
preoccupied in other departments of Natural 
History. The same conchologist suggested in 
the article named that Pristina, (used by my- 
self) should be replaced by Axnceya. 
] am very thankful to Mr. Pilsbry for naming 
the group of Zonitide 1 allude to, after me, 
but a remarkable clausilioid genus, found by 
the celebrated French traveller, Mr. Victor 
Giraud, at the southwest end of Lake Tangan- 
yika, and published by my friend Mr. Bour- 
guignat in 1885, was called Anceyva ; Anceyella 
is also used in Conchology for a cyclostomoid 
shell. I propose for Pristina Anc. (Anceya, 
Pilsbry, not Bourg.), the name of Pristiloma. 
I also propose tc name Cavlospira, Anc. (not 
Hall), after Mr. Averell, the honorable editor 
and publisher of “The Conchologists’ Ex- 
| change,” Averellia,Anc.,and Peczlostola, Anc., 
very near H. augusticollis, Martens, another | 
Chinese form, and the type of Stegodera, Mar- 
tens. ‘The texture and color are precisely the
