The generic place of this and the three following species is very 

 doubtful; but the mouth is rather too wide to justify their being 

 classed with the Fyrene group of Golumbella, which the general 

 aspect of the shell suggests as their place.

Shell, — Small, thin, porcellaneous white, with fine riblets and 

 delicate spirals, a rather high, subscalar spire, a large blunt mamil- 

 lary apex, deep suture, small body, a short rounded contracted base, 

 and a small, lop-sided, emarginate snout. Sculpture. Longitu- 

 dinals — there are on the last whorl about 25 narrow, sharply 

 raised, flexuous, little ribs, parted by flat furrows of twice their 

 breadth ; these decrease in number up the spire ; they die out 

 toward the point of the base ; they bend quickly to the left below 

 the suture, advancing to the right lower down : the furrows and 

 snout are scored with fine lines of growth. Spirals — there are 

 feeble, rounded, sparsely-set threads, of which about eight on the 

 penultimate whorl ; immediately below the suture they are very 

 faint, but are present. Colour yellowish porcellaneous white. 

 Spire high, rather cylindrically conical. Apex blunt, mamillary, 

 with an exceedingly small impressed tip; it consists of two globose, 

 smooth, embryonic whorls. Whorls 5^ to 6 in all, with a rounded 

 shoulder defined by a very slight angulation, below which the 

 whorls are subcylindrical ; the last is scarcely tumid, with a 

 rounded contracted base prolonged into a stumpy, slightly re- 

 verted, emarginate snout. Suture sharp, impressed, rather deep, 

 horizontal. Mouth oval, slightly angulated above, and produced 

 below into a short, broad, open, and somewhat oblique canal 

 Outer lip thin, a little expanded, arched, advancing below, con- 

 tracted at the canal ; there is at the top a faint approach to a 

 sinus. Inner lip concave above, straight on the pillar, which is 

 in front little oblique, but has a slight twist ; a thin narrow glaze 

 defines it throughout. H. 0*28. B. 0*13. Penultimate whorl, 

 height 0-08. Mouth, height 0-14, breadth 0-09. 



This species has some faint resemblance to Golumbella {Pyrene) 

 costulata, Cantr., but is less compact, has a more impressed suture 

 and more rounded whorls, wants the densely set minute spirals, 

 and has a longer snout ; the apex, too, difi"ers from that species.
