32. GrpBuLA scAMNATA (Fischer), 
Trochus (Gibbula) scamnatus, Fischer J ourn. de Conch., 1878, p. 66; 
Coq. Viv., p. 394, pl. cxvun, fig. 4. 
Gibbula scamnata (Fisch.): Pilsbry, Man. Conch., ser. 1, vol. xi, p. 220, 
pl. xxx, fig. 6. 
Shell small, subperforate, conoidal, cinereo-olivaceous, with spiral 
blackish bands; whorls 6, somewhat convex with 5-6 elevated lire 
on the penultimate whorl; last whorl subangulate, base convex with 
7-8 concentric lire, the interstices narrow. Aperture subrhomboidal, 
sulcate within; columella arcuate, a little reflexed and almost 
covering the umbilicus. Alt. 7, diam. 7°5 mm. (Fischer). 
Hab.— Brighton, Otago; Oceanica (Fischer). 
Specimens collected by Mr. A. Hamilton undoubtedly belong to 
this species, for which no definite locality was given by Fischer. 
The species closely resembles Cantharidus rufozona, A. Ad., from 
which, however, it may at once be distinguished by its partly open 
umbilicus, its arcuate columella without any indication of a tooth, its 
larger size, and darker colour. 
This is perhaps the undescribed form of Cantharidus mentioned by 
Pilsbry under C. tenebrosus (t.c., p. 124).

Portion of radula of Gibbula Suteri (E. A. Smith). 
Shell small, turbinate, imperforate, uniformly black or grey, 
ciereous, pink, etc., longitudinally variegated and tessellated with 
white. Whorls 5, convex, rapidly increasing, faintly spirally striate. 
Last whorl angled at the periphery. Aperture rounded, outer lip 
sharp, columella arcuate, its expansion completely covering the 
umbilicus, leaving only a slight pit; umbilical tract white, impressed. 
Base slightly convex. Alt. 4, diam. 4mm. 
Hab.—Lyttelton Harbour (H. §.); Lyall Bay (A. Hamilton). 
On examining the animal I found that a jaw is present and the 
Tadula is decidedly that of the genus Gibbula. A figure of the teeth
