penultimate whorl, and about 14 on the body- whorl ; the inter- 

 stices slightly broader than the lirae, and ornamented with fine, 

 dense, straight growth-lines. Colour white. Spire elevated- 

 conic, a little higher than the aperture : outlines almost straight. 

 Protoconch papillate, of 2 smooth lightly convex whorls, the 

 second high. Whorls 5, regularly increasing, moderately con- 

 vex, indistinctly flattened below the suture ; base slightly con- 

 tracted. Suture impressed, but not deep. Aperture a little 

 oblique, high and narrow, sides subparallel. rounded above, 

 with a short widely open and truncated canal below. Outer 

 lip thin and sharp, slightly angled above, straight in the middle, 

 and oblique below, denticulated on the outside by the spiral 

 riblets ; sinus just below the suture, broadly rounded, not deep. 

 Columella subvertical, smooth, almost straight, turned to the 

 left towards the canal below ; inner lip thin and very narrow, 

 spreading over the slightly excavated parietal wall. 



Diameter, 17 mm. ; height, 4-5 mm. 



Type in my collection. 



Two specimens, one adult. 



Remarks. — This species is allied to D. conquisita, Suter, 

 which, however, is broadly shouldered, has less and further- 

 apart spiral ribs, and the growth-lines much more raised and 

 more distant. 



37. Daphnella psiia, n. sp. Plate XXVII, fig. 10. 



Shell very small, fusiform, thin, almost smooth, but the 

 base distinctly spirally striate, white. Sculpture : Excessively 

 line microscopic striae are present on all whorls, those of the 

 protoconch excepted, crossed by fine dense straight growth - 

 lines ; the body- whorl with broad flat equidistant spiral ribs, 

 numbering about 20, with narrow linear interstices ; they are 

 distinct at the base, but more or less effaced on the upper part 

 of the whorl. Colour light-yellowish-white. Spire elevated- 

 conic, with a blunt apex, a little higher than the aperture ; 

 outlines straight. Protoconch of 1| smooth and polished 

 whorls, the nucleus broadly rounded. Whorls 5, regularly in- 

 creasing, very flatly convex ; base lightly contracted. Suture 

 moderately impressed. Aperture slightly oblique, high and 

 narrow, sides subparallel, angled above, with a short broad 

 and truncated canal below. Outer lip thin and sharp, gently 

 curved above, broadly rounded below. Columella vertical, 

 smooth, straight, but bent to the left below ; inner lip very 

 narrow, extending over the lightly excavated parietal wall. 



Diameter, 2-6 mm. ; height, 6 mm. 



Type in my collection. 



One specimen.
