624 SUPPLEMENT. 
To the localities given, add :— 
Hab. [E. Muxico:] San Rafael, Jicaltepec (Cockerell *°). 
[S.E. Mexico :] San Carlos, due east of Oaxaca, in open country with shrubby 
vegetation of Cacti and Mimose (Hoge). 
N.W. Costa Rica: Guanacaste (Jus. Berol.: from a dealer). 
Pilsbry’s specimens ®9 were from Vera Cruz, whence I have already recorded the 
species. 
Subgen. Artonta (p. 142). 
Pilsbry, in Tryon’s ‘ Manual of Conchology,’ (2) ix. p. 67, places H. flavescens in the 
subgenus Praticolella (see anted, p. 623); and (loc. cit. pp. 199, 200) H. trypanom- 
phala and H. magdalenensis in the subgenus Epiphragmophora, with the other North- 
American Arionte. 
Helix magdalenensis (p. 144). 
Epiphragmophora magdalenensis, Dall, Proc. U.S. Nat. Mus. xix. p. 339°. 
Of this species Mr. Dall? notices a variety from the San José Mountain, Sonora 
(Dr. Mearns). We states? that H. magdalenensis also occurs in California, at altitudes 
between 900 and 6000 feet. 
Helix aspersa (p. 145). 
Helix aspersa, Stearns, Proc. U.S. Nat. Mus. xiv. p. 96 (1891) *. 
To the localities given, add :— 
Hab. |CenrraL Mexico:| Puebla (Meaican Geographical Commission, U.S. Nat. 
Mus.}®), 
The acclimatation of this species at Santiago in Chile has been noted by P. Strobel 
[Atti della Soc. Ital. Scienze Nat. xi. p. 552 (1868)]. 
Subgen. Lysinoii (p. 145). 
Pilsbry, in Tryon’s ‘ Manual of Conchology,’ (2) ix. p. 191, follows me in uniting the 
three species humboldtiana, eximia, and ghiesbreghti under one group, Lysinoé, Adams, 
to which he gives generic value, at the same time placing it among the ‘* Belogona 
Euadenia”’ of the Helicide. Von Ihering (1892), on the contrary, and H. Fischer 
(1899), separate H. humboldtiana as a distinct subdivision, Humboldtiana, from Lysinoé ; 
but they agree also in stating that it differs anatomically from the species of the 
European group Pomatia. ‘The subgeneric name proposed by Fischer and Cross for 
H. eximia and H. ghiesbreghtt has been changed by H. Fischer (1899) to Priodontura, 
Odontura being preoccupied.
