Affinity. — This species has a general resemblance to Astralhim 

 aureum, but is more depressed, umbilicated, and has a different 

 ornamentation and coloration. 



Claneulus consobrinus, sjjec. nov. Pi. i., figs, i, la. 



Shell perforate, depressed, pinkish-brown, sparsely black-dotted. 

 Spire low-conic, apex acute ; whorls live, suture subcanaliculate ; 

 body-whorl obtusely bi-angular at the periphery, base somewhat 

 convex. Aperture rounded, oblique ; outer and basal margins 

 lirate-dentate. Columella oblique, neither tortuous above nor 

 entering the umbilicus; its front edge plain, except a tooth at the 

 base. Umbilicus wide and deep, its margin crenate-dentate. 



Ornament of penultimate w^horl of four equal and equidistant 

 granulose lirse, and obliquely-transverse raised threads ; of the 

 body-whorl, a small granulose lira interposed between the third 

 and fourth, anterior to the fourth are two smaller equally-distant 

 from one another, the fifth is slightly granulose, whilst the sixth, 

 which is at the periphery, is Inroad and obtuse ; the interspaces 

 between the lira3 are faintly spirally striate ; base with seven 

 concentric lira?, the inner ones subgranose, the outer ones plain, 

 with a few coincident strife in the interspaces. 



Dimensions. — Height, 8; basal diameters, 14 and 12 mm. 



Localities. — Cast-up : Holdfast and Aldinga Bays, S. Yorke 

 Peninsula ; Head of Great Australian Bight (several examples). 

 Dead shells dredged in Yankilla Bay, Backstairs Passage, and 

 Corney Point in 30 fathoms (Dr. VercoJ. 



Affinity. — This species has the form of C. plebeiits, but I can- 

 not attach it to any of its recognisable varieties or to any 

 described congener. It is slightly more depressed than C. plebeius, 

 whilst it attains nearly twice the size ; the umbilicus is deeper, 

 reaching to or beyond the junction of the penultimate and last 

 whorls. The absence of the trenchant tessellated sculpture and the 

 equidistant granular lirse of the posterior area of the body-whorls 

 are distinctive characters, which are furnished by the ornament. 



Claneulus euehelioides, sine. nov. Pi. i., fig. 8. 

 SJtell turbinately concoid, somewhat solid, opaque, concolorous 

 (reddish); whorls about six, the ordinary spire-whorls separated 

 by a canaliculate suture and flattened posteriorly, the last whorl 

 convex in the anterior-third ; base flatly convex, falsely umbili- 

 cated, the columella entering the umbilical depression, which is 

 shallow and moderately narrow. Aperture oblique, rhomboid- 

 oval ; outer lip slightly depressed at the suture ; outer and basal 

 margins thin. Urate, and iridescent within (the lira? not extending 

 to the margin). Columella oblique, straight, rib-like, with an 

 attenuated keel elevated into a tooth-like prominence at the base, 

 and separated from the basal margin of the aperture by a deep
