in hilineatm, and either smooth or feebly striated in carolinensis ; he 
thinks that in this genus the quality of the jaw cannot be maintained as 
a generic character, as it varies even in the species ; Reis. Arch. Philippin.

Helix. The variations of bands in the genus Helix are discussed by 
S. Clessin, who distinguishes (among the European species) the following 
3 principal groups, characterized by similar arrangement of the bands; — 
(1) Typical, 5 bands; the sub-genera Tachea, Maculayia, Her us, and 
Pomatia IPentalainia, Ad. Schmidt]. (2) 4 bands, but these often split 
into a largo number of bandlets ; Xerophila. (3) 1 to 3 bands ; the sub- 
genera Campylica, Chilotrema, Arionta, and Fruticicola. JB. Ver. 
Augsb. xxii. pp. 52-67. 
Helix. Species from Europe and adjacent countries : — 
S. Clessin has examined the different species allied to and often united 
with Helix rufescens (Penn.) = striolata (C. Pfr.), of which he describes 
and figures a var. subcarinata, adopting the following as distinct 
species : — II . clandestina (Hartm.), danubialis, sp. n., montana (Stud., 
C. Pfr.) = erecta (Hartm.) = rufescens, var. minor (Jeffr.), and coelata 
(Stud.). JB. mal. Ges. i. pp. 177-194, pi. viii. figs. 1-6.
