the South-African Stenogyrinas. 267 



Hah. Natal, Lower Tugela River, Pinetown, Tongaat 

 {Burnup) ; Pietermaritzburg {Connolly). Young shells, 

 apparently inseparable from this species, from Delagoa Bay 

 {Connolly) . 



A stouter form than Euonyma crystallina, and easily distin- 

 guished from E. turriformis by its almost colourless sculpture- 

 less whorls and highly polished transparent shell. Even more 

 variable in breadth than most members of the subfamily. 



The type was described as being 14 mm. in length and 4 

 in breadth, but I have seen specimens measuring 12*0 x3"5 

 and 13'5x5"5 respectively. 



6. Opeas eulimoide (Preston). 



1909. Subulina eulimoides, Prest. Ann. & Mag. Nat. Hist. iv. p. 499 

 (fig-)- 



Hah. Natal, Howick. 



Evidently not a Subulina, 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 lepidum, sp. n. (PI. VI. fig. 12.) 



Shell small, elongate, turriform, subrimate, pale olivaceous, 

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

 tapering, apex rounded. Whorls 6, rather convex, regularly 

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

 extremely faintly sculptured with regular curved stria?, 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 arched forward. Columella very slightly concave, 

 margin narrowly reflexed, almost concealing the minute 

 rima. Callus none. 



Shell 7-0x2-5, aperture 2*3 x 1*2, last whorl 3*7 mm. 



Hah. Cape COLONY, Fern Kloof, Grahamstown {Farquhar) ; 

 Port Elizabeth {Crawford) . 



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 

 Curvella delicata, "Gibbons'" Taylor, while it cannot be 

 associated with such as 0. clavulinum, Potiez and Michaud,
