second ami third abtut equal in size and more convex than 

 the rest, which become less ventricose as they increase in 

 distance between sutures, the last one or two being unusually 

 flattened. The second whorl microscopically, remainder 

 clearly covered with rather coarse curved striae. Suture im- 

 pressed. Aperture ovate, slightly rounded at base. Peristome 

 thin, simple. Outer lip a little outcurved, arched forward in 

 profile. Columella erect, margin narrowly reflexed. Callus 

 none. 



Dimensions (spec. max. in Brit. Mus.) : shell 20*2 X 5*1, 

 apeiture 5"3 x 2"5, last whorl 8'7 mm.

Although the species is very easily distinguishable, it 

 varies greatly at different stages of growth, and the largest 

 specimens that I have been able to procure are unfortunately 

 dead and calcined. The contour of the spire is variable, 

 sometimes evenly tapering, sometimes rather crooked and 

 slightly attenuate towards the apex. Tiie columella, too, in 

 immature specimens is straight, while the slightly reflexed 

 margin leaves a clearly visible rima ; in mature shells it 

 becomes twisted and the margin practically aduate, so that 

 the shell is almost imperforate. E. pruizenensis differs from 

 E. cacummata, M. & P., whose form it somewhat resembles, 

 in its longer aperture, dullish epidermis, and minute rima, 

 E. cacuminata being highly glossy and imperforate. 



The presence of sculpture on all but the mamillate apex of 

 the new species is a noteworthy feature, the marking on the 

 second whorl being almost visible without a lens. 



13. Euonyma siliqua, sp. n. (PI. VI. fig. 10.) 



Shell elongate, rather subulate, imperforate, pale olivaceous, 

 usually tinged with yellow, thin, normally glossy and nearly 

 transparent. Spire produced, very slightly gradate, evenly 

 but rather slowly tapering to the very bluntly rounded apex, 

 which is nearly 1 mm. across. Whorls 8, pretty regularly 

 and rather rapidly increasing in distance between sutures, but 

 varying noticeably in circumference in different shells; 

 convex, rather deeply impressed at the suture ; the first two 

 smooth, remainder rather irregularly sculptured with very 

 fine curved striae, plainly visible at intervals to the naked eye, 

 but otherwise hardly discernible without a lens. Aperture 

 ovate, rounded at the base; peristome thin, simple; outer lip 

 curved outward ai;d slightly bowed forward; columella erect, 

 thickened and twisted upward, with no trace of reflection.
