98 G. & H. Nevill — Descriptions of new Marine Molliisca. [No. 2, 



nutely and closely longitudinally striated ; columella with a moderately 

 spread callosity, which is slightly rugose ; canal long, not recurved ; four 

 denticulations within the aperture, the two upper ones very thick and promi- 

 nent, outer lip much thickened, slightly emarginate at the upper part. 



Long. 5f, diam. 3i mil. 



Ceylon — Rare. 



This is the smallest species of the genus as yet descrihed. 



EULIMA ACUTOEMIS, n. Sp., PI. VIII, Fig. 1. 



Shell very elongate, sharply pointed, white and shining, solid, fiexuous ; 

 whorls 17, cylindrical, slightly angulate at their base, except the last whorl 

 which is short and rounded ; no impressed line at the suture, varices obliquely 

 continuous ; aperture oblong, slightly produced in front, rounded at base ; 

 columella reflected, outer lip scarcely thickened. 



Long. 10, diam. 2f mil. 



Dredged at the Andaman Islands by Mr. Wood-Mason. 



Rare. The above character will easily distinguish this graceful shell 

 from its nearest allies, E. lactea and flexuosa, A. Ad. 



(Coll. Indian Museum and Rev. J. Warneford.) 



Eulima (Aectjella) mieieica, Nevill. 

 J. A. S. B. 1874, {Mauritius). 



We have lately noticed that H. and A. Adams described a genus under 

 the name of Bacula, allied to Hulima, (in A. & M. N. H., 1863, Vol. XI, p. 18) 

 founded on a species from China, which they called striolata ; this shell pro- 

 bably belongs to the same genus as the species from Mauritius, which we 

 described as above ; in either case our name for the genus, or sub-genus, will 

 stand, there being a genus Baculum described prior to 1863. 



Mitea (Ttjeeictjla) cetjentata, Ch. 



Fig. 1438-9, from the E. Indies. 



Typical specimens, as admirably figured by Chemnitz, are found at the 

 Nicobars (probably the locality whence the type came) and Andamans ; 

 they have two white bands on the last whorl, with 10 to 11 distant, 

 fiexuous ribs, nodosely angled at the upper part ; the transverse grooves 

 rugose, approximately equally incised, forming tolerably regular and oblong 

 granules where they intersect the ribs. 



Long. 19^, diam. 8 mil. 



M. C'ETJENTATA, Ch. vai*. PEOXIMA. 



This is the shell from the Philippines figured by Reeve (fig. 126) for 

 cruentata, Ch. ; it is a form which is often mistaken for Reeve's II. armillata ; 

 it has 16 ribs on the last whorl, is a trifle less fiexuous, and less prominently
