Journal of conchology . sh, but in placesreddish. In the lower portion of the visceral mass lies the largeopaque white mucous gland. The central nervous system appears to be as in L. philippii^ but theganglia are distinctly granulated.^ The buccal mass is small, about 3 mm. long and mm. broad,and consists of a round antechamber with dilatations at the sidefollowed by a narrower portion which bears about 12 transversestriations on the upper surface. The crop is enormous compared tothe size of the other organs. It consists of a flattish tube about2 mm. wide, bent on itself four or five times and deep yellow incolour. As it lies, the length is about 5 mm., but if straightened outit would be 20 or 25 mm. long. It shows signs externally of beingdivided by a whiteish furrow representing the lumen which is mm. wide, and not always strictly median. The radula contains 6teeth in the ascending series, of which the first is rudimentary, and 9in the descending series. (Text Fig. 4). In the heap are more than. b a del. Text Fig. 4.—a. Three teeth from the radula of Lobigtr A smaller tooth from the heap. 20 teeth of various sizes piled together quite irregularly. The teethare yellowish at the base and colourless in the upper part. The shapeis much as in Z. philippii, but perhaps a Httle stouter and more the figure they are shown as seen somewhat from below, which I See Vajssiferes figure, Opislh. de Marseille, Suppl., pi. iii., fig. 40. 3IO JOURNAL OF CONCHOLOGY, VOL. 11, NO.

On the tip uf eachare two notches, one wider and rounder than the other, whichform three small denticulations. Some of the smaller teeth in theheap show a striation like that of Lophoceniis, but much stronger. Itis not, however, visible in the teeth which are in the row. Thesalivary glands are grape-like clusters of simple or compound ovat
