wanting, remaining whorls 14, convex, each with 4 spirals, of which the uppermost is placed 

 at a small distance from the suture, the third is the most prominent and the fourth borders 

 the lower suture, these spirals are not really beaded, but waved by the radiating grooves and 

 flat ribs covering the shell; on the second and third spiral however, they have more or less 

 the appearance of compressed beads, moreover I see very fine growth-striae. Colour whitish, 

 with yellowish-brown upper spirals and small brown spots between the beads of the third spiral; 

 last whorl carinated by the fourth spiral, its base radially striate, bearing a fifth spiral. Aperture 

 subquadrangular, with a small notch in the upper corner, columellar lip callous below, canal 

 short, directed towards the right and backwards. 

 Long. (incl. canal) loYg, lat. 2^4 Mill.

 Stat. 99. North-Ubian, Sulu-archipelago. 16 — 23 M. Lithothamnion-bottom. i Spec. 



Larger than the type, which is only 14 Mill, in length, the Siboga-specimens are 17 

 and 18 Mill., the latter is adult, the former is still young. 



7. Triphora sp. 



Stat. 95. 5°43'.5 N., ii9°4o'E. Sulu Sea. 522 M. Stony bottom, i Spec. 



The specimen is not adult, the nuclear whorls are wanting, it is worn and bleached. 

 I cannot identify it with any of the known species, but it is in too bad condition for description 

 and I only make mention of it, as it would be remarkable for the great depth at which it has 

 been dredged. It is however not certain that it has really lived there. 



8. Triphora (Iniforis) fuscoapicata Sowerby.

Stat. 93. Pulu Sanguisiapo, Tawi-Tawi-islands, Sulu-archipelago. Reef, i Spec. 



The specimen is slightly larger than the type, having a length of nearly 6^3 Mill, instead 

 of 5Y3, but a cotype received from the author, from the island Cebu, the original locality, is even 

 7 Mill, in length. Both specimens perfectly agree. The brown apical whorls are not smooth, as 

 has been stated in the description (1. c.) but only the uppermost one may be called so, the 

 other are bicarinate and are crossed by narrow riblike striae.
