NEW SPECIES OF CDL1MAC12A. 461 



Helix Lamarckiana. Plate XII., Fig. 11. 



Testa orbiculato-convexd, subcarinatd, rufo-fuscd, subtenui, irregulariter striata, minute per- 

 forata; anfractibus quaternis, superne planulatis; aperturd magnd, transversa; labro acuta ; co- 

 lumelld laevi. 



Shell orbicular convex, somewhat carinate, reddish-brown, rather thin, irregularly striate, per- 

 foration small ; whorls four, flattened above ; mouth large, transverse ; lip acute ; columella smooth. 



Hab. Philippine Islands. W. W. Wood. 



My Cabinet. 

 Diam, 2,4, Length. 1.2 inches. 



RemarTis. — This fine large Helix seems to be most nearly allied to H. mono- 

 zonalis, Lam. It may be distinguished by the absence of the band, by the 

 whorls being more flat above, and by the striae, which, on the inferior part of 

 our shell, might be said to be wrinkled. Immediately below the periphery, 

 the brown colour is deep, and shades off to nearly the colour of the superior 

 part. If we were strictly to adhere to Lamarck's division of CarocoUa, this 

 species might be placed in that genus. 



Helix Cuvieriana. Plate XII., Fig. 12. 



Testa orbiculato-convexd, carinatd, tenui, longitudinaliter minute, striatd, infra periphxriam 

 tenebrosd, superne pallidd; minute perforatd; anfractibus quints, subplanulatis, supra auturas 

 impressis; aperturd parvd, transversd; labro acuto; columelld Isevi. 



Shell orbicular-convex, carinate, thin, longitudinally and minutely striate, darkened below the 

 periphery, above pale ; slightly perforate ; whorls five, rather flattened, impressed above the su- 

 tures ; aperture small, transverse ; lip sharp ; columella smooth. 



Hab. Philippine Islands. W. W. Wood.

 Diam. 1.2, Length .6 of an inch. 



Remarks. — The carination of some of the specimens before me would war- 

 rant this species being placed with Lamark's CarocoUa. This species, in its 

 general aspect, is very like CarocoUa bicolor, Lam. It is, however, not so solid
