Paramelania cramgramdata, Bourguignat : ii, pi. xiv, fig. 18; iii, 

 p. 202; Martens, p. 209; Martel & Dautzenberg, p. 180, 

 pi. viii, fig. 25 ; Moore, ii, p. 245, fig. 26, radula. 

 This species was originally described from two dead and rather 

 worn shells. The large series of specimens obtained by Mr. Moore 

 shows that it varies considerably, especially in size, the largest 

 example being 32 mm. in length, whereas the smallest is only 19. 

 The latter is qnite adult, however, having the thickened, perfected 

 peristome, and the same number of whorls as the larger shell. When 

 describing this species I felt some hesitation in separating it from 

 P. Damoni. However, an examination of the large series of both 

 species collected by Mr. Moore shows that they are quite distinct. 

 The distinguishing features originally pointed out are maintained, 

 namelj^, the narrower excavation or tabulation at the upper part of 

 the volutions, and the more rounded and more coarsely granulated 

 ribs and spiral lirse. The angle of the body- whorl is not spinose as in 

 P. JDamoni.

Lavigeeia. 



Lavigcria, Bourguignat, ii, p. 33, pi. xiii, figs. 13-17, pi. xiv, figs. 1-7 

 (1888) ; iii, p. 178 ; Martens, p. 207, as a subgenus of 

 Paramelafiia. 



JVassopsis, Smith: Ann. & Mag. Nat. Hist., 1890, vol. vi, p. 93; 

 Moore, ii, pp. 250-6, figs. 33-8. 

 The animal has been described by Moore under the name JVassopsis. 



This genus is separable from Edgaria on account of the tubercular 



prominence on the columella. Its operculum is different from that 



of Paramelania.

 Paramelania grandis, Bourguignat : i, p. 69.
