A not quite developed specimen is 8^^ Mill, in length, one of the smallest ones 7^4 Mill. 

 This species may be readily distinguished by its large size ; in shape it resembles R. peracuta 

 Watson, but differs by its armature of aperture.

Shell small, ovate, with short, conical spire, rather smooth, whitish. Whorls about 5, of 

 which about \^\„ form a smooth, inflated nucleus, post-nuclear whorls scarcely convex, separated 

 by a conspicuous suture. Sculpture consisting of 3 spiral, infrasutural lirae, the lower one 

 accompanied by a rather conspicuous groove, and of about 13 grooves from periphery to base; 

 the infrasutural lirae are crossed by numerous, fine plicae, occupying also the upper part of 

 otherwise smooth median zone. Aperture pear-shaped, angular above; jDeristome not developed, 

 columellar side of body-whorl enamelled, without teeth, columella with 2 folds.

Though this specimen is not full-grown and consequently the characters of the aperture 

 and even the measurements, have in part no great value, the very peculiar sculpture may serve 

 to recognize this species, if more complete materials might be procured. This sculpture seemed 

 to be too remarkable, not to describe and name the species.

I have applied the name of Ascanius, in accordance with Bergh, in his monograph L 

 of the Siboga-Expedition. By examining the gizzard-plates, I found that the specimens under 

 consideration, agree with those of Ph. qitadripartita, and not with those of Ph. rttbra Bergh, 

 which that author has recorded from Stat. 251.
