which has a still thicker shell ancl a purplish hue near the aperture, but sufficiently agrees in 

 every other respect, to be nothing more than an individual variation. 



Minolia ornatissima seems to be allied to M. tasmanica T. Woods and T. eudcli Desh. 

 but differs in colour, in particulars of a sculpture and especially in the umbilical angle, which 

 is surrounded by a brown zone, not mentioned in the allied species. The radula agrees in many 

 respects with that of Minolia vitiliginea Mke. as figured by Troschel (Gebiss der Schnecken, 

 Band II, PI. 25, fig. 24). The rhachidian tooth (R) is subquadrate, without reflected margin, the 

 upper corners are rounded, the lower ones angular, the upper margin is slightly pointed in the 

 centre. At the first lateral (1) I can detect no reflected margin, but the proximal upper corner, 

 which is slightly pointed, and the proximal margin are thickened, the shape is oblong; the 

 second (2) and third laterals are similar, the fourth one is simple, the fifth (5) has a very complicate 

 structure, which could not well be traced, by its being covered by the adjacent teeth. The uncini 

 are elongated, with simple cusps, at least I could discover no smaller denticles at their sides. 

 This radula at once separates the species from the genus So/aric//a, to which it might be 

 referred on account of its conchological characters. 



2. Minolia sp. 



Stat. 2i7- Sailus Ketjil, Paternoster-islands. Up to 28 M. Coralsand. 1 Spec. 



The specimen is young and not taken alive. I can not identify it with any species I 

 know, but it is in too poor condition for description. 



3. Minolia sp. 



Stat. 258. Tual-anchorage, Kei-islands. 22 M. Lithothamnion-bottom. 1 Spec. 

 The specimen is in still worse condition than the preceding one. 



Solariella S. Wood. 



1. Solariella olivaceostrigata n. sp. PI. III, fig. 5; PI. IX, fig. 7. 



Stat. 95. 5 34.5 N., ii9°4o'E. 522 M. Stony bottom. 4 Spec. 

 Stat. 100. 6°ii'N., i20°37'.sE. 450 M. Dead coral. 1 Spec. 



Shell clepressed-conoidal, rather thin, upper whorls nacreous, with a very beautiful purple 

 and o-reen tinge, last whorls whitish, adorned on the upper surface by rather broad, olivaceous 

 streaks. Whorls 6, the nucleus smooth, foliowed by a 2 d and 3 d whorl, each with 6 spiral lirae 

 of which the upper ones are slightly undulate, on the fourth whorl the lirae disappear, only the 

 upper one remains and becomes beaded, it borders the broadly canaliculated suture, which in 

 this and in the fifth whorl, is crossed by conspicuous striae, which run partly also on the convex, 

 smooth, lower part of these whorls; near the last whorl the beads disappear, the suture becomes 

 less broad and deep. This last whorl is nearly smooth, except for most tender spiral and radiating 

 striae, only visible under a strong lens, and a few remote deeper striae near the suture, being
