HELIX PISANA, 383 
The sub-var, Major is described as one-third larger than the type. 
The sub-var. maxima is deseribed as a large form of sub-var. chambardi and 
as measuring 20-22 mill. in diameter and 16-19 mill. in altitude. 
The sub-var. irregularis is described as irregularly grown, somewhat gibbons, 
and with finely malleate ultimate whorl, Diam. 25 mill. ; alt. 15 mill. Though 
this form is really a somewhat irregularly grown shell, it is perhaps more suitably 
dealt with here than under a separate heading. ;

SHELL smaller; diam. 13 mill. ; altitude 9 mill. 
The ELuparypha pisana var. parvula Mousson, from 
Fuerteventura, Canary Islands, is probably identical. 
The sub-var. sardoa of Ziegler is described by Wester- = 
lund as small, with partially closed umbilicus, and continuous Fic. 432.—H. pisana 
and interrupted banding. Diam. 12-13 mill. ; alt. 9 mill. var. é0r, Tenby, Mr. 
The description of the same variety given by Moquin-Tandon — 4: G Stubbs. 
*‘whitish, with continuous and interrupted brown bands” is brief and even less precise. 
The sub-var. thusurosi (Helix thusurosi Bourg. olim) is identical in size with 
the var. minor, and has a narrow umbilicus, a thin, transparent and whitish shell, 
with a very large body-whorl, slightly angulate at its origin. 
The sub-var. subplanatais described as a shell possessing 
a depressed spire, with carinate penultimate and body-whorl, 
and a more elongate aperture. The illustrative figure here 
reproduced shows a shell measuring 134 mill. in diam. and 10 Fic. 433.—//. pisana 
mill. in alt. var, subplanata Pall. 
This variety scarcely possesses suflicient individuality to Cees ven 
« ce « rt le 
entitle it to a distinctive name, and may perhaps be more 
suitably placed under the var. anor on account of its diminutive size than with 
the depressed forms as probably intended by the author,
