114 BEV. R. BOOG WATSON ON THK 



crosses the body, and runs straight down the pillar, which is 

 very narrow and patulous, with a sharp prominent edge and a 

 very minute furrow behind it. H. 0-096. B. 0-034. Penulti- 

 mate whorl, height 0-017. Tip of apex 0-004. Mouth, height 

 0-03, breadth 0-017. 



Than E. Jeffreysiana, Brus., this is a slightly stumpier form ; 

 the whorls are not in the least convex, the apex is blunter and 

 more truncated, the outer lip is much more laterally expanded, 

 and the basal line much more oblique. The form of the mouth 

 and the slightly larger tip distinguish it from the young of E. 

 intermedia, Cantr. 



3. EuLiMA CHAUNAX, u. sp. (xav)'a^, a gaper, so called from 

 the openness of the mouth.) 



St. 24. (As above.) 



Shell. — Small, straight, rather broad, with suture slightly im- 

 pressed ; whorls a very little rounded below, the last rather 

 large and somewhat suddenly contracted ; with a short flattish 

 base, a large very open mouth, and a small rounded tip. Sculp- 

 ture none. Colour translucent ivory-white. Apex small, 

 rounded; but the two slopes do not perfectly agree. Spire 

 shortish, perfectly straight, and with entirely similar profile-lines. 

 Whorls 9, flattened above, but just perceptibly swoln below, and 

 faintly contracting to the inferior su.ture ; the last is a little 

 large and contracts rather suddenly (yet not so as to form 

 an angulation) to the constricted and flattish base. Suture very 

 slightly impressed. MoiUh large, pointedly ovate. Outer lip 

 well arched and patulous ; on the edge it is deeply sinuated 

 above, prominent in the middle, and retreating in front to the 

 point of the shell, where it forms a broad gutter with a slight 

 projecting lip. Inner lip : a thin, narrow, marginated glaze spreads 

 across the body ; the pillar-edge is sharp, narrow, not patulous, 

 very slightly oblique to the left, and is truncated in front. 

 H. 0-15. B. 0-06. Penultimate whorl, height 0-028. Tip of 

 apex 0-007. Mouth, height 0'05, breadth 0-036. 



The proportions of the shell, its size, and the form of the 

 mouth markedly distinguish this species from E.fasciata, which 

 it slightly resembles. 



4. EuLiMA CHASCANON, u. sp. (j(c(ff/caroj', a mask with a 

 ga|)ing mouth.)
