386 NEW MIAiRINE MOOJLUSCA. 



three, rounded; aperture moderate, widening slightly to- 

 wards the rounded front; outer lip massive, heavilv 

 varixed, partially ascending the spire, from which it pro- 

 jects at almost right angles to form a broad shoulder, and 

 then bends sharply down with a strong outward curve; 

 from a side view it is also strongly curved towards the 

 front; the inner edge, which is convex, is armed with 

 about seven irregularly spaced denticles; columella 

 roundly convex above, but hollowed in the space occu- 

 pied by the plaits, which are four in number, rising 

 obliquely, of nioderate size, the upper one toeing the 

 smallest. 



Length, 3.3 m.m.; breadth, 2.5 m.m. 



Locality: Type 40 fathoms three miles east of 

 Schouten Island, with many others, all dead; also in 60 

 and 80 fathoms, but becoming few^ in the deeper water. 

 It resembles M. ochracea Angas, but is a very much 

 broader shell, with a shorter spire. From AI. laevigata 

 Brazier, which occurred with it, it differs, besides being 

 only half the size, in considerable difference of outline, in 

 the much more feeble plaits, and far less heavily toothed 

 outer lip. It is also related to }>!. vercoi, from which, 

 however, it is still more distinct. 



Named in honour of Mr. Gatliff, who has done so 

 much for the Victorian mollusca. 



MARGINELLA GABRIELI, N.S.P. (PL. XIII., 

 FIG. 9.) 



Shell biconical. or fusiform, shining, translucent, but 

 not very thin, with an elevated spire and blunt apex; 

 white, with four orange bands; whorls four, rather 

 rounded; aperture narrow, almost linear, but widening 

 anteriorly, wdiere it is rounded; outer lip moderately 

 thickened and smooth; columella nearly straight, with 

 four well developed plaits, which become smaller and 

 less oblique, and also retreat further within the aperture 

 as they ascend. The anterior band is narrow, and passes 

 between the two upper folds; the second and third in the 

 centre of the whorl are near together, and enter the aper- 

 ture about its upper third; the fourtli is at the suture, and 

 continues on the spire. 



Length, 4 m.ni.; breadth, 2 m.m.
