EULIMA LACHRYMA. 75 



Family Eulimim:. 



The family is thus defined in the last edition of Zittel's ' Handbuch ' : " Small, 

 polished, elongate-conic shells with oval aperture ; the axis often distorted ; 

 nucleus dextral." 



Genus EULIMA^ Risso. 



" Rather thick, highly turreted ; suture distinct ; spire plane, that of the 

 summit mammellated ; aperture oval, attenuated to the right" (Risso, 1826). 



The sole record of this genus is *Eulima laevigata (34, 43, 48). There is, how- 

 ever, some confusion here. The name was first applied by Lycett (" Great Oolite 

 Moll ," pi. xv, fig. 4), to a shell from " near Scarborough," which indicates what 

 is now called the Scarborough limestone, but his figure does not correspond with 

 the description. In the Supplement (pi. xxxi, fig. 3) he applied the same name to 

 another shell, differing from the first in character. In the first he lays stress on the 

 character : " Very subulate, the length of their whorls being nearly equal to their 

 transverse diameter " ; in the second he says : " Whorls narrow, the height slightly 

 exceeds half of the opposite diameter." This latter, from the Cornbrash, is fairly 

 drawn, but coincides better in shape with the former figure. Finally Hudleston 

 describes the original by the exact terms used to distinguish it from E. communis, 

 and draws a figure of a form from the Cornbrash different from either of Lycett's. 

 In his last monograph (" Inf. Ool. Gast.," p. 244) Hudleston classes the Scar- 

 borough limestone species with Pseudomelania, and queries both Lycett's figure 

 and his own from the Cornbrash. In these circumstances it appears that we 

 cannot call either of them E. laevigata, but must give new names to both.

1863. Eulima laevigata, Lycett, Great Oolite Mollusca (Pal. Soc), p. 114, pi. xv, fig. 4 (not Suppl. 

 pi. xxxi, fig. 3). 



Type. — Sutural angle, including the last whorl, 32°. There are eight whorls, 

 the last being swollen. The upper whorls are about half as high as their diameter. 

 The surface is slightly convex and polished, the sutures being not deep. There 

 are very fine curved lines of growth, and still finer spiral lines, almost invisible 

 even with a lens. The aperture is pointed posteriorly, and quite round anteriorly,
