A stouter form tli:in Euonyma crystallina, i\n<\ easily distin- 

 guished from A\ turrifonnis by its almost colourless sculpturo- 

 less whorls and highly polished transparent shell. Even more 

 variable in breadth than most members of the subfamily. 



'J'he type was described as being 14 mm. in length and 4 

 in breadth, but I have seen specimens measuring 120 x 3*5

Evidently not a Subnlina, as the columella is straight, and 

 apparently best placed in Opeas on account of its small size. 

 I have not seen this species; Mr. Preston informs me that 

 the whorls are much less convex than in E. crystallina, 

 M. & P., to which it appears rather nearly allied. 



7. Opeas lepidtim, sp. n. (PI. VI. fig. 12.) 



Shell small, elongate, turriform, subrimate, pule olivaceous, 

 thin, glossy, semitransparent. Spire produced, acute, evenly 

 tapering, ape.x rounded. Whorls 6, rather convex, regularly 

 increasing ; the first smooth, the second nearly so, remainder 

 extremely faintly sculptured with regular curved striic, which 

 are only just visible to the naked eye. Suture clearly 

 defined. Aperture short, oblong-oval, base rounded. Peri- 

 stome thin, simple. Outer lip strongly curved outward and 

 gently archeil forward. Columella very slightly concave, 

 margin narrowly reflexed, almost concealing the minute 

 rima. ( 'alius none. 



Siiell 7-0 X 2-5, aperture 2-3 x 1-2, last whorl :V7 mm.

Mr. Farquhar observes that this pretty little species regu- 

 larly occurs, seldom exceeding the above-quoted dimensions, 

 in a locality very favourable for producing the full growth of 

 the shell. It compares closely with the figure and description, 

 but not with actual specimens in the British Museum, of 

 Curve/la delicaUi, "Gibbons" Taylor, while it cannot be 

 associated with such as 0. clavulinum, Potiez aiid MichauJ,
