The specimen of lilnirna f^apiilar's has the body well distended, 

 revealing its form as in life. It is beautifnlly marbled Avith red 

 spots similar in form to those which adorn the shell. The foot is 

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

 posteriorly, and terminating in a curious httle tail-like projection. 

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

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

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



Nassa eusulcata, n. sp. (Plate II. 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 

 moderately convex, longitudinally ribbed and spirally grooved : 

 ribs rendered slightly nodulous by the intersecting sulci, and 

 narrower than the interstices: grooves rather deep (5 on the 

 penultimate, and about 16 on the last whorl), the one next to the 

 suture being broader and deeper than the others, dividing the 

 tops of the longitudinal ribs: suture slightly channelled. Tast 

 whorl rather more than half the entire length of the shell, slightly 

 inflated, contracted at the base. Aperture moderately wide, 

 narrowing posteriorly into a shallow canal; anterior canal short, 

 rather wide: columella covered with a rather thin proiccting 

 callus, roughly and irregularly ribbed within; outer lip slightly 

 crenulated; interior strongly lirate. 



Length, 19; breadth, 10 millim. 



Hab. : — Month of Tu?ela River N. by W., distant iS miles. 



Depth. 46 fathoms. Bottom, mud. 



This shell is allied to N- lizrscciis. Phil, which species varies 

 considerably in its proportions, &c., but the ribs are more distant, 

 and the spire seems to be invariably more sharply acuminated. 



Xapsaria CKACir.is, n. sp. (Plate II. fig. 10). Shell whitish, 

 suffused with light brown, fusiform, spire acute, turrcted; whorls 

 10. the first 1^ rounded, smooth, the rest roundly convex, longi- 

 mdinally strongly ribbed and delicately striated, spirally lirate: 

 ribs rather thick and prominent, crossed by the spiral ridges of 

 ''A'hich (in the penultimate and antepenultimate whorls) the two 

 middle ones arc the most prominent, and, being raised in crossing 

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

 not channelled. Last whorl abotit half the total length of the 

 shell, roundly convex, constricted belov/ the middle, and terminat- 

 ing at the base in a slightly refiexed rostrum of moderate length, 

 and outside the aperture in a thick, broad varix- A]-)erture sub- 

 ovate, strongly lirate within: outer e(\Q;e sharp, very slightly re- 

 fiexed ; columella covered with a thin callus, which is raised in a 

 sharp ridge above the tmibilical region : canal moderately long 

 and reflcxcd. ^ . , -»^
