1 PHILINE. 
With this species have been united by many late writers, forms of 
Philine from the Red Sea, Australia, ete., which so far as the shells 
are concerned seem to be almost, if not quite inseparable. It 
remains to be seen whether the dentition and gizzard-plates will 
offer features differentiating the Atlantic and Mediterranean form 
from those of the Indo-Pacific. The descriptions of these forms 
have been given above, but the question of their status is of course, 
an open one.

Shell resembling in shape a miniature Scaphander lignarius, but 
more cylindrical; it is ofa delicate texture, semitransparent, and of 
a glistening and iridescent lustre ; sculpture, numerous and close-set 
spiral and parallel rows of minute oval dots which are interwoven 
and arranged like the links of a chain; some of these rows being 
intermediate, and apparently squeezed or compressed, at the sides 
become merely fine lines; the front edge or base of the mouth and 
top of the outer lip are exquisitely fringed with sharpish points, 
like short teeth of a comb; color clear white when the shell is ex- 
tracted from the animal, afterwards becoming milk-white; spire 
slightly prominent; whorls 3; the body whorl (as usual in this 
genus) is disproportionately large and voluminous; the other two 
are small with an indistinct and thickened nucleus; suture deep 
and channelled ; mouth acute-angled above, and greatly expanded be- 
low, with a squarish base; outer lip gently curved, folding inwards 
on the upper part; the top of this lip is below the spire ; inner cor- 
ner cloven or excavated, so as to cause a disjunction of the suture in 
front and a partial separation of the body-whorl from the next ; 
inner lip forming a rather thick and broad glaze. (Jeffr.).
