REPORT ON THE GASTEROPODA. 405 



surface is finely fretted with microscopic spirals; on the snout are about 10 coarsish 

 somewhat crumpled threads, with minute sharp lines in their interstices. Colour tawny 

 white, with a broadish chestnut band below the periphery, and less continuous stains of 

 the same up to the suture and on the base and snout. Spire high turreted, conical, small 

 and sharp at the point, with an almost continuous outline in spite of the deep suture. 

 Apex partly broken, but evidently consisting of 2 or 3 polished, rounded, turbinated 

 whorls. Whorls 9, exclusive of the embryonic whorls, ventricose, rounded, of regular 

 increase ; but the last is somewhat disproportionately large ; the base is rounded, but con- 

 tracted and a little flattened towards the snout, which is moderate, both as to length and 

 breadth, and advances straight in the axis of the shell, but with a twist and a strong back- 

 ward bend on itself. Suture is itself invisible, but is very strongly defined by the deep 

 undulated furrow, which at the top of the whorls sinks in behind the longitudinal ribs and 

 cuts them off from the base of the preceding whorl. Mouth oval, rather small, deep, 

 perpendicular, and very little oblicpie ; from its lower left corner rises a strong, deep, 

 e(pial, slightly curved canal, whose direction is distinctly, but not strongly, to the left. 

 Outer lip : its nearly semicircular curve is slightly flattened about the middle, and bags a 

 little toward the lower outer corner ; at its upper corner it advances a good deal and rises 

 a little on the body-whorl ; its sharp and contracted margin, which projects from the last 

 and massive varix, is crenulated ; remote from the edge it is scored by 9 rather long, 

 narrow, sharp-topped teeth, the first and last two of which are stronger than the rest ; the 

 first is a little remote from the upper angle of the mouth, while the last is on the very 

 edge of the canal. Inner lip spreads patulously, but not broadly, on the body -whorl in a 

 thin, defined, porcellanous layer ; it runs straight down the pillar as a sharp projecting edge ; 

 it is scored within by about 9 teeth, of which the first is short and strong, the second long 

 and strong, the third and fourth long and weak, the fifth, sixth, and seventh short and weak, 

 while the eighth and ninth are strong and coil round the point of the pillar. On the left 

 side of the canal are 4 or 5 tubercles. H. l - 37 in. B. 0*84. Penultimate whorl, height 0*26. 

 Mouth, height (exclusive of canal) - 49, breadth 0-3. Length of canal 0'29, breadth 0-07. 



This species has much resemblance to Nassaria acuminata, Keeve, but is shorter, squatter, coarser, 

 with more ribs, is deeper in suture ; the canal is shorter, more recurved, and more twisted.
