Length 18 millim., width 8g millim. ; apertureand canal 9 millim. long, 3 millim. wide.Hah. Port Curtis, 7 fms,22. Urosalpinx contracta.Buccinum contractum, Reeve, Conch. Ico)i. fig. 53.? Buccinum funiculatum, Reeve, I. c. fig. 61.Var. = Urosalpinx iuuotabilis, Smith, Proc. Zool. 8oc. 1879, pi. xx.tig. 32.Hah. Prince of Wales Channel, 5-7 fms. {Goppinger) ; PhilippineIslands {Reeve) ; Bombay ( W. T. Blanford) ; Japan for U. innotahilis.The operculum of this species resembles that of Purpura. Thespecies is rather variable in form, the number of costs), in colour, andthe length of the basal or anterior canal.The typical form is rather longer, and has a more prolonged canalthan the variety from Japan, has more brown colouring, and anadditional longitudinal rib. All have from seven to eight elongatedenticles or lira) within the labrum, which is thickened within andwithout, and acute and crenulated along the margin.23. Tritonidea curtisiana. (Plate V. fig.

Volutionsabout 8, obliquely coarsely costate, and spirally closely ridged, atrifle convex. Costse nine on a whorl, attenuated and producedalmost to the base of the last. Sj)iral lira) prominent on the ribs,four in number on the upper whorls, and about sixteen on the last.A])erture small, ovate, narrowed anteriorly, bluish white.

Port Curtis, 1-11 fms. {Coppnnger).This speciesis represented in the present collection by a singlespecimen : and it is remarkable on account of the peculiarity of itscolour, its small size, and comparative solidity.24.
