As to the radula of this species, it is a very small and rather obscure object, and only by teasing it to pieces, I could get an idea of the shape of the teeth. The uncini quite cover the median rows, and cross even the uncini of the opposite side. The rhachidian or median tooth has a subquadrate basal part, with rounded, convex posterior and less convex lateral margins. It has a broad, triangular cusp, with one small median denticle and about 6 smaller ones on each side. The laterals one on each side, have a transversely triangular shape, with an unarmed, arched upper and concave proximal and basal margin, with blunt points at the proximal and distal extremities of the basal margin. On each side I see at least 3, but I suppose there are 4 uncini which are long, slender and strongly curved. Though this radula has some resemblance with that of "Aporrhais", like Verrill (Mollusca of the New England coast. Transact. Connecticut Acad, of arts and sciences, Vol. VI, May 1884, p. 1S6 and 188) has stated, and like his figure (I.e. pi. 31, fig. 14b) affirms, I cannot agree without doubt with his view that it should be taenioglossate, as the "Siboga"-specimen has a radula with at least 9 rows of teeth and probably 11. The nacreous character of the shell agrees with the Rhipidoglossa, and so does the larger number of uncini. I should think the genus will belong to the Rhipidoglossa with a restricted number of teeth, such as Basilissa. As however only a knowledge of other anatomical particulars, the position and structure of the gills, of the heart etc. can decide the question I have left the family near "
