The specimen of Ebunia papillaris has the body well distended, 

 revealing its form as in life. It is beautifully marbled with red 

 cpp^c m'^^Hoi- I'n forni tn those v/h'ch ^dorn the shell. The foot is 

 broad and high, rounded in front with a double margin, tapering 

 Tjosteriorly, and terminating in a curious little tail-like projection. 

 The head is small and flat; tentacles rather short and tapering; 

 eyes at the outer base of the tentacles on sHght prominences ; 

 proboscis rather long and inflated ; siphon rather short and thin. 



Nassa eusulcat.'\, n. sp. (Plate TI. fig. S). Shell pale straw 

 colour tinged with light brown; spire rather long, sharply acumi- 

 nated ; whorls nine, the first two smooth and rounded, the rest 

 moderatrlv convex, longitudinally ribbed and spirallv grooved ; 

 ribs rendered slightlv nodulous by the intersecting sulci, and 

 narrower than the interstices: grooves rather deep (q on the 

 penultimate, and about i6 on the last whorl), the one next to the 

 suture being broader and deeper than the others, dividing the 

 tons of the longitudinal ribs: suture sligfhtlv channelled. Last 

 whorl rather more than half the entire leneth of the shell, slio-htlv 

 hiflated. contracted at the base. Aperture moderatelv wide, 

 narrowinp- posteriorlv into a shallow canal; anterior canal short, 

 rather wide: columella covrred ^vith a rather thin nroiectino- 

 callus, roughlv and irreeularh^ ribbed within; outer lip slightly 

 crenulated; interior stronglv h'rate. 



Length, 19; breadth, 10 mihim.

T^enth. 46 fathoms. Bottom, mud. 



This shell is allied to N- Ik'cscciis. Phd.. which species varies 

 considerablv in its proportions. (*^c., but the ribs are more distant, 

 and the spire seems to be invariably more sharply acuminated. 



Nassarta okacii-IS, n. so. (Plate II. fig. 10). Shell whitish, 

 suffused with light brown, fusiform, spire acute, turreted: whorls 

 TO. the first t4 rounded, smooth, the rest roundly convex, longi- 

 tudinallv stronc^lv ribbed and delicately striated, sn'ralh' lirate: 

 ribs ratl^cr thick and prominent, crossed bv the sniral rido-es of 

 ^vhich (in the penultimate and antepenultimate whorls) the two 

 niidd^e ones arc the most prominent, and. beino- raised in crossing 

 the ribs, give a biansfular character to the whorls: suture linear, 

 not channelled. Last whorl about half the tot-^l len."-th of the 

 •^hell, roundly convex, constricted belov/ the middle, and terminat- 

 ing at the base in a slig-htlv refiexed rostrnm of moderate leneth, 

 and outside the aperture in a thick, broad varix- Apc-turp sub- 

 ovate strong-lv lirate within : outer edse sharp verv slio'htlv re- 

 flexed : columdla covered with a thin callus. Avhich is raised in a 

 sharp ridfre above the umbilical region ; canal moderately long 

 and reflf^xed.
