ZOOLOGICAL LITEIIATUIIE. 
injiecta (Say), rugeli (Shuttl.)? tridentata (Say), muUani (Bland), fallax (Say), 
introferens. (Bland), hopetonensis (Shuttl.), vuUuosa (Gould), and loricata 
(Gould). Binney & Bland, L c. pp. 123-134. 
Odotropis (Balinesque). This name is preferred to Mesodon (Raf.) by 
Cooper, Am. Journ. Conch, v. p. 212. \_Odotropis does not mean toothed 
whorl,” as the author says, but toothed keel,” and therefore can only be 
meant for a keeled species. It will be better not to disturb the names which 
are now adopted by a considerable number of conchologists, by introducing 
mysterious productions of Rafinesque.]

authors, and proposed to be used for H Columbiana (Lea). Cooper, ibid,

duced, bei'landieriana (Moricand) and griseola (Pfr.), Texas. Binney &

Helix (subgenus Euparypha) areolata (Sow.), tryo7ii (Newcomb), pandor<B 
(Forbes), and lecis (Pfr.). Binney & Bland, 1. c. pp. 177-180. 
Arionta (Leach) and Lysino'e (A. & II. Adams). J. G. Cooper places a 
great number of Californian species in these two divisions, which are re- 
garded by him as genera, y\z. Jidelis (Gray), dupetitthouarsii (Desh.), ayi'esiana 
(NeAVC.), 7'ufocincta (Newc.), re^nondii (Tryon), infumata (Gould), mormonum

nickliniana {\ idii) , tudicidata (Binney), californiensis (Lea), keUttlii (Forbes), 
caipenteri and tryoni (Newc.) in the genus Arionta ; he states that in 
he has found four to six ribs on the jaAV, in Injsino'e mormonum and facta 
(NeAvc.), eight. Notes on several other pecidiarities of these species are added. 
Am. Journ. Conch, v. pp. 204, 211, and 218. 
Helix (subgenus Polymita) varians (Menke), islands of Florida, and H. 
depicta (Grateloup), New Orleans, are doubtful species. Binney & Bland, 
pp. 184 and 187. 
Helix (subgenus Ampelita [?]) rowelli (Newcomb), California. Binney & 
Bland, 1. c. p. 185. — Cooper is right in objecting to this species being placed 
in the Madec.issian group Ampelita. Am. Journ. Conch, v. p. 211. 
Localities of some North- American species are corrected by Cooper, Am. 
Journ. Conch, a'. p. 217.
