118 EEV. E. BOOG WA-TSON ON THE 



smaller and slimmer. Than E. rtdila, Carp., it is much slimmer, 

 and the apex in particular is very much sharper. 



8. EuLiMA ACANTHTLLis, n. sp. (aVai'0u\\ts, a small prickle.) 

 July 1875. Eeef off Honolulu, Sandwich Islands. 40 fms. 

 Shell. — Very small, very slightly bent, transparent, with a very 

 fine somewhat oblique suture, flat-sided whorls, a straight oblique 

 shortish base, a pear-shaped flat-ended mouth, and an excessively 

 sharp tip. Sculpture none. Colour pure very glossy transpa- 

 rent white. Apex quite extraordinarily small, not perfectly- 

 regular, being slightly pinched-in at the very tip, which is rounded 

 but slightly acuminated, and not perfectly symmetrical. Spire 

 very high and narrow^ nearly but not quite straight, one side 

 being slightly more oblique than the other. Whorls 8, almost 

 perfectly flat-sided except towards the tip, where they are slightly 

 rounded. Suture rather oblique, scarcely impressed except 

 towards the tip, where it is a little distinct ; the septum between 

 the whorls shines through the shell, and of course makes the 

 suture easily recognizable. Mouth pear-shaped, but a little 

 truncated in front. Outer lip almost straight, arched at the 

 outer basal corner, and a little straight in front ; its edge is 

 deeply sinuated above, prominent in the middle, and very re- 

 treating in front, where it forms a broad deep gutter. Inner lip : 

 a thin narrow glaze with a defined edge crosses the body and 

 extends down the pillar, on which it is expanded and slightly 

 twisted ; from the upper corner of the mouth to the point of the 

 pillar the line is nearly straight or very slightly concave. H. O'l. 

 B. 0-02. Penultimate whorl, height 0-01. Tip of apex 0-002. 

 Mouth, height 0-024, breadth 0-01. 



This species, which is much smaller than E. oxytata, is very 

 like a young form of that species, but it increases more rapidly, 

 so that it has a whorl more than a specimen of E. oxytata of the 

 same size ; the apex is as small, but is the last thing more 

 abruptly contracted. The E. Manzoniana, Issel, from the Eed 

 Sea, is larger for the number of whorls, somewhat broader in 

 proportion to the length, the suture is less oblique, and the base 

 is longer and more rounded.
