EXPLANATION OF THE PLATES AND WOOD-CUTS. 



Rare — we have seen but one specimen and that is very imperfect. 

 Loc. Soomrow. 

 Fig. 2\. Cassis [Cyprcecassis, Stutchbury,) sculpta. Ovate, transversely sulcated ; 

 aperture narrow, the outer lip plaited, the inner smooth. Height If inch, diameter 

 1 inch. 



Strongly resembhng Cassis {CyprcBcassiSySiwtchhuxy,) Testiculus {Bucc. Testi- 

 culus, Linn.), but smoother, and with a narrower aperture. 

 Loc. Soomrow. 

 Fig. 22. Turbinellus affinis. Subfusiform, swelled in the middle, ornamented with 

 many transverse ridges and a row of flatted tubercles near the upper margin of 

 each whorl ; beak produced transversely, ribbed ; columella 5-plaited. Height 4 

 inches, width 2 inches. 



Very nearly related to Turbinellus Scol//mus, Lam., but it is more elongated, has 

 smaller tubercles, and 5 not 3 plaits on the columella. 

 Loc. Soomrow. 

 Fig. 23. Mitra scrobiculata. (Brocchi, Vol. ii. 317. t. iv. f. 3.) ? This is the same as 

 the fossil found at Piacenza. It is often larger than our figure. 

 Loc. Soomrow. 

 Fig. 24. Mitra fusiformis. Fusiform, pointed, striated ; stride distant, deep, punc- 

 tated, suture entire ; columella with 4 plaits. Height ,2 inches, diameter 9i lines. 

 Somewhat resembling Mitra adusta of Lamarck. 

 Loc. Soomrow. 

 Fig. 25. Volupta jugosa. Fusiform, pointed, transversely striated, costated ; costee 

 many, rounded, terminating in points above the suture ; aperture elliptical, elon- 

 gated ; columella with 3 plaits. Height 2^ inches, diameter 1| inch. 



This differs from V. Magorum of Brocchi, in the form of the ribs, and the small 

 number of plaits upon the columella, and from V. costata, (M. C. t. 290.) in the 

 form and in the greater number of the ribs. 

 Loc. Soomrow. 

 Fig. 26. Valuta dentata. Turbinate, striated, spire short, conical, pointed ; whorls 

 crowned with tubercles which surround a concave space ; aperture elongated ; the 

 outer lip thick, crenato-dentated within. Height 1 inch 7 lines, diameter 1 inch. 

 Loc. Soomrow. 

 Fig. 27. Cyprcea Jmmerosa. Obovate, depressed with 3 protuberances upon the back, 

 and one on each side. Length 2 inches, width 1| inch. 

 Loc. Soomrow. 

 Fig. 28. Cyprcea Prunum. Oval, ventricose ; aperture narrow, slightly curved with 

 about 20 teeth on each side ; base convex ; beak small, not much produced ; a very 

 even shell. Length nearly 2 inches, width \\ inch. 

 Loc. Eyerau. 

 Fig. 29. Cyprcea digona. Ovate, ventricose, slightly depressed ; base flattened on 

 each side ; beak expanded, prominent, with sharp edges ; teeth on each side the 

 aperture, above 20. An obscurely-marked species. Length 13 lines, width d^ lines.
