18 PHILINE. 
outer edge of each is keeled or ridged ; suture deep and channelled ; 
mouth squarish, remarkably wide and large, nearly truncated at the 
base; outer lip forming an obtuse angle at the junction of the front 
and base ; the top is higher than the spire, and it projects outwards; 
inner corner deeply and widely cloven, so as to make the disjunction 
of the outer whorl! from the next very conspicuous; inner lip forming 
a narrow but thick ledge or fold, behind which is a slight depres- 
sion. (Jeffr.). Alt. 2°5, diam.1°9 mill.

The keeled spire will serve to distinguish this from any other 
species of Philine having conspicuous spire and chain-like sculpture.

Shell oblong, convex, very thin and fragile, nearly transparent, 
and of a polished luster; sculpture, none on the body-whorl; but 
the spire has two keels or ridges, one at the outer edge of each whorl, 
and the other in the middle, giving this part an angulated appear- 
ance, color clear-white, becoming opaque in dead specimens; spire 
flattened, placed somewhat obliquely; -it is quite exposed and 
occupies the top of the shell; whorls 23, irregularly twisted, but dis- 
tinct; suture deep and excavated; mouth oval, truncated above, 
wide and rounded below, its area equals about two-thirds of the 
under surface; outer lip expanded, squarish at the top, and gently 
curved in the middle; it is level with the spire, viewed mouth 
downward, and is below it, viewed mouth upwards; outer corner 
angular and projecting; inner corner considerably receding and 
acute-angled ; inner lip forming a broad glaze on the upper part, 
and reflected on the pillar; there is no umbilical groove or de- 
pression. (Jeffr.). 
Alt. 1°8 mill.

Jeffreys’ figures would hardly justify the union of his species with 
that of Sars, but the description leaves little doubt of their identity.
