 Plate XXXIX. 

 Trochus camelophorus ( = rope-bearing), n. sp. Figs. 1, la. 



Shell solid, conical, rose-coloured with darker markings 

 of the same. Whorls 5^, somewhat bulging at the periphery. 

 Sculpture : Rounded cinguli with rope-like markings, three on 

 the third whorl, then four, five above the aperture, six on the 

 outer lip above the periphery ; between the third and fourth 

 ropings on the penultimate whorl a narrow cingulus appears. 

 Protoconch two-whorled, smooth, waterworn. Sutures marked 

 by a deep groove behind the first roping of succeeding whorl. 

 Base with six flat spirals separated by a slightly narrower 

 furrow ; on these spirals are two or three subspirals. The 

 colouring only appears on the raised surfaces ; it fades to- 

 wards the false umbilicus, which is funnel-shaped, with two 

 deep spiral grooves, the posterior of which does not reach the 

 columella-edge. The columella is nearly vertical, very slightly 

 arcuated, and has what looks like a prominent tubercle near 

 its insertion (it is really the end of a spiral fold) ; the ridge 

 separating the two grooves is rounded and highly polished. 

 Aperture sub quadrate ; lip simple, advancing at the suture. 

 Height, 1 cm. ; major diameter, 12 mm. 



Hab. Cape Maria van Diemen. 



Animal and operculum unknown. 



One specimen in my collection has the grooves in the funne] 

 narrower and the dividing ridge wider and slightly concave. 

 The pink colour of this shell may be due partly to exposure. 



Mr. C. Hedley very kindly compared the type with the 

 Trochi in the Australian Museum, and writes, " I should regard 

 this shell as a very distinct new species." 



Trochus (Clanculus) takapunaensis, n. sp. Figs. 2, 2a. 



Shell with five slightly rounded whorls, of which one and 

 a half are smooth. Sculpture : Smooth rounded spirals, of which 

 the two upper are close together and the others far enough 

 apart to admit a fine spiral thread in the radially striated 

 hollow between them ; above the peripheral spiral on the body- 

 whorl is a narrower one which appeared in the suture of the third 

 whorl. Colour yellow-grey, with very dark irregular patches 

 all of which shade into white from left to right. Sutures deeplv
