point. Outer lip ascends slightly on the body-whorl, towards 

 which at the same time it is a very little pinched in. From this 

 point to the edge of the canal it forms a very equable curve ; 

 slightly retreating at first so as almost to form a shallow open 

 sinus, it is thrown out into a wing-like projecting expansion in 

 the middle. It is patulous, reverted, thin on the edge, but 

 thickened within by a glossy porcellanous callus, stained dark 

 brown at the ends of the spiral threads. The short anterior 

 canal bends over towards the pillar, is well defined, round, with 

 the oral lips a little contracted and its front margin a good deal 

 reverted. The pillar is short, straight, narrow, at the point 

 sharp and bent to the left, with a narrow and twisted edge ; in 

 colour porcellanous white. Inner lip is glossy, rising into a 

 tooth on the first intraoral thread, spread out on the body, with a 

 slightly thickened and well-defined edge on the pillar. H. 1*6.

This species in form and colour is not unlike Cerilliium 

 longicaudaturn, Ad. & Eve., or C. attenuatum, Phil., but in details 

 of whorls and of sculpture it is totally different. 



6. Ceeithium phoxum, n. sp. ((polos, tapering.) 



July 29, 1874. Levuka, Fiji. 12 fms. 



Shell. — Sharply conical, on the base contracted and a little ob- 

 liquely flattened, longitudinally ribbed with spiral tubercled 

 threads, of a certain waxy whiteness tinged with yellow and ruddy 

 brown. Sculpture. Longitudinals — there are from ten to eleven 

 straight but oblique riblets on each whorl ; on the earlier whorls 

 they are pretty continuous, with a sinistral twist round the spire, 

 but on the later whorls they become less regular. Besides these 

 there are fine scratch-like lines of growth. Spirals — on the 

 upper whorls there are four, on the later five, which, as they cross 

 the riblets, rise into tubercles. They are parted by intervals of 

 two to three times their width, and in these intervals two or three 

 narrower but similar threads appear, as they do also on the base, 

 where there are two stronger circumbasal threads and a multi- 

 tude of finer hair-like spirals, which extend to the point of the 

 pillar. Besides these the whole surface is covered with finely 

 fretted microscopic spirals. Colour a delicate waxy straw- 

 colour, with stains of a brownish flesh tinge. Spire very slightly 

 scalar, straight, and very sharply conical. Apex fine. Whorls 14,
