ultimis ter minoribus asperis, omnibus acutis, prominulis, inter- 
stitiis quadratulis, ultimo anfractu 9-carinato, quorum tres cirea 
peripheriam maxime conspicui; apertura fere rotunda, labro 
tenui, crenulato; columella alba, crassiuscula, recta, nitida. 
Long. 12, lat. 8 mm. 
Hab. Persian Gulf, Koweit, 10 fathoms, mud and sand. 
A very select species, having the vitreous heterostrophe 
apex so characteristic of the genus; turritelloid in shape, 
elegantly attenuate, the upper whorls with two principal 
earinze and three lesser keels, the lowest whorl nine-keeled, 
of which three, at the periphery, are the most important. 
The quadrated spaces at the interstices, and lire extending 
longitudinally over the lower carine, have a beautiful effect 
as regards. the sculpture. The colour is either pale chestnut, 
dark chestnut, brown, or blackish. The two other species 
from the same region, Af. gracillima and zmitampis* (of 
which the latter has since occurred in the Gulf of Oman, 
lat. 24° 58’ N., long. 56° 54’ H., 156 fathoms), differ in size, 
colour (both being white), and, in the case of AZ. gracillima, in 
squareness of aperture. A general family likeness, however, 
pervades all the members of this exquisite genus. This new 
species, and also the next, will be figured subsequently.

Among very numerous examples of S. homalazis, Melv., 
which appears frequent from Bombay northwards, three 
specimens occurred of a far more select form, which is now 
described. Its sculpture is most elaborate, the very acutely
