lossil at. man\‘ stations, including tlic older and newer Pliocene 
near Messina, and so far apart as Trontheini and Havannah. 
Observers have rej’ortod that a living specinieiij on being put into 
l:esh water, ejected a bluish liquid, with a strong smell of var- 
nish. It is a beautiful triangular shell of the thinnest crystal. 
Localities — Cosmopolitan. 
C. balantium Rang 1834 (Cleodora). Triangular oblong, 
glassy; posterior inflexed above; transversely sulcatcd above and 
below; inflated in the middle, sides compressed; dorsum with 
three longitudinal ribs which cunv^erge posteriorly; aperture ov- 
ately transverse, narrowing to the sides. Length 28, breadth 16 
mm. Dredged — Bcachport, Cape Jaffa, S. Aust., also Western 
Australia, 120 miles west of Euda, 110-500 fathoms. Localities 
— Atlantic Ocean. Indian Ocean, southern portion, and off N. 
Ciuinea. 
Styliola Lesueur 1825. Conicalj straight, considerably elon- 
gated; surface smooth, with a dorsal groove not parallel to the 
iixis of the shell, but slightly oblique, turning from left to right, 
with only the anterior extremity (which ends in a rostrum) in 
the median line; embi'yonic j'lortion onK' vaguely separated from 
rest of shell, and ending in a pointed apex. Type— S. recta Les- 
iieur ( = Clio subiila i^ang). Many conchologists have 
regarded Creseis I'lang l'^28, as a synonym. d’lus opinion 
is based on a misinterpretation of the t)']“>ical species, Styliola 
recta Lcsueui'. (without description) which has been taken by 
these autlnirs for Clio acicida. 'But the description given of 
the genus Styliola enables one to infer tliat Styliola recta is really 
Clio siibida and not Clio acicida. Structural features show S/yli- 
ola more nearly related to Clio tlian to Creseis. On the con- 
trary, forms included in the latter genus have retained some more 
archaic characters of the Limacuudae (Pclseneer). 
S. subula Rang (Cleodora) . PL I, bg- 19. “d'he I'aper- 
ing Styliola.'' C'onical, much elongated, (Tliquely truncated an- 
teriorly, and terminated posteriorly by a slightly swollen point; 
very line transverse striations all over; dorsal surface with a 
small groove from the anterior edge obliquely t<) near the sum- 
mit; mouth rounded, oblique to tlie axis of the slicll, irregular 
and sharp at the edge; upper Up, which is produced beyond the 
lower, terminates on the middle line in a point, mure or less 
projecting, funning sometimes a kind of beak which is only the 
prolongation of the dorsal groove. Length 10, breadth 1.5 mm. 
jOredged — Cape Borda, -Neptune Islands, Cape Jaffa, also 80 miles 
west of Eucla 62-300 fathoms. Localities — Apparently common 
in every ocean.
