HELIX-HELICOPHANTA. 69 



scarcely noticeable zones ; aperture ample, obliquely oblong ; lip 

 subacute, subreflexed ; inner lip dilated above. 



Alt. 45-48, diam. 35-38 mill. (Grat.) 



I do not think that this Helix is the Goudotiana. The compar- 

 ison I have made with Ferussac's figure causes me to regard it as a 

 distinct species. It is much larger, less globulose, more elongated, 

 and consequently of a Bulimus shape. The aperture is very large, 

 oblong, inclined, smooth within, a little translucent, and notwith- 

 standing the greenish-fawn color, traces of the two spiral zones of 

 the last whorl are visible within. Last whorl very large, elevated, 

 ventricose, and at least four times longer than the short, obtuse 

 spire. ( Grat.')

I have translated above Grateloup's original diagnosis and com- 

 ments, and given on pi. 66, fig. 60 a fac-simile of his figure. From 

 these it will be seen that Reeve and Pfeiffer are in error in their 

 identifications of this form. 



Grateloup's description and figure were probably drawn from 

 rather immature specimens. I have on the strength of this supposi- 

 tion, considered the following form a variety ; it has however, ap- 

 parently good claims to specific rank. 



Var. PHENAX Pilsbry. PL 66, fig. 61 (type) ; pi. 11, fig. 39. 



Shell oval or oblong, imperforate, but with a narrow, deep chink 

 or rimation behind the reflexed columellar lip ; solid but not thick ; 

 opaque ; rich chestnut-brown, sometimes a trifle tinged with olive, 

 and encircled by two dark brown bands, one at periphery, the other 

 above it. The surface is slightly shining, and shows when closely 

 examined, a very fine, dense granulation all over. The granulation 

 is produced by the decussation of growth-striae by close, fine spiral 

 impressed lines. Spire short, obtuse ; apex a trifle sunken ; suture 

 impressed. Whorls 4, convex, the last very rapidly increasing, 

 oval, descending, somewhat depressed in the baso-umbilical region. 

 Aperture oblique, egg-shaped, rather acute above, rounded beneath, 

 livid-flesh-colored inside and showing the two bands. Peristome
