the depth of the attached valve it approaches to 0. Meadii(M. C 2o2, 

 f. 1 and 4.), but is not waved like that. 

 Loc. near Joonagrea and Kotra. 



(Fossils from the Tertiary FormationSj Cutch.) 



Bulla lignaria, Linn. This agrees perfectly with the recent species as 

 far as we can ascertain from specimens which are not perfect ; but it is 

 quite distinct from both the fossil shells described, by Deshayes under 

 the same name. 



Loc. Soomrow. 



NaUca ohscura. Globose, umbilicate ; spire small, pointed ; whorls 

 ab"ut 5, convex, flattened, and ornamented at the upper e lge with fine 

 diverging plaits ; umbilicus partly filled with a semi-cyliiidrical, oblique- 

 ly-truncated callus. Height 1| inch, diameter the same. 



Nearly related to N. Epiglottina^ Lam., but distinguished by the flat- 

 tened upper mai gins of the whorls ; and to Nerita ccmrena of Brocchi, 

 vol. ii. 296. 



Loc. Soomrow. 



Natica callosa. Obliquely depressed ; spire small, hardly projecting ; 

 umbilicus covered by the thickened and expanded inner lip : aperture 

 very large. Height 2 inches, diameter 1| inch. 



A very distinct species. 



Loc. Soomrow. 



Globulus ? ariguUferus. Oblong, obliquely striated : spire produced : 

 whorls about 4, with their sides and upper edges flattened ; umbilicus 

 open, rather large. Height and diameter f inch. 



The eleva'ed lines or striae advancing towards the aperture as they 

 descend the sides of the whorls form a peculiar character. The aper- 

 ture appears to be small. 



Loc. Borders of the Runn. 



Solarium affine. Convex above, flattish beneath, marked with diverg- 

 ing strise on both sides ; whorls 4 or 5, with a deflected entire carina, 

 above which are 4 furrows placed at nearly equal distances, and below, 

 2 furrows near the carina, and 2 near the umbilicus, which is large, with 

 a crenated edge. Diameter ]| inch, height I inch. 



Perfectly distinct from Solarium perspectivum, which it somewhat re- 

 sembles. 



Loc. Soomrow. 



Trockus cognatus. Conical with straight sides ; whorls numerous, or-
