4. Cypr#a eraciiis (Slender Cowrie). Cyp. testd oblongo-ovatd, 
antice gradatim acuminatd, pallide flavescente-brunned, maculis 
dorsalibus irregularibus pallidé brunneis, lateribus basalibus brunneo 
punctatis, punctis paucis distinctis ; basi pallescente ; latere postico 
columellari subgibboso ; apertura latiusculd, subspirali ; dentibus 
labii externi prominentibus equalibus, circa octodecim, labii colu- 
mellaris equalibus, anticis paululiim majoribus, pariter circa octo- 
decim ; sulco columellari antico depresso, postico inconspicuo de- 
presso; extremitatibus canalibus latisque prominentibus ; spird 
conspicud, profundé umbilicatd. 
Shell oblongo-ovate, gradually tapering towards the anterior end, 
smooth and shining, of a light fawn-colour, with very light brown 
irregular markings about the back, and a few distinct dark brown 
dots on the edges of the base of the shell on both sides, bands 
indistinct ; inside of shell milk-white ; base somewhat lighter in 
colour than the back; posterior half of the columellar side rather 
gibbous, outer side of base somewhat depressed in the centre por- 
tion; aperture subspiral, rather wide; teeth of the lip prominent 
and even, extending in no degree on to the lip (only denticulating 
its edge), about eighteen in number, and about as many also on the 
columellar side, which are larger anteriorly, even, terminating ex- 
ternally in a line at the edge of, or rather just within the aperture, 
and internally, proceeding straight across the columellar groove to 
terminate at its inner edge the anterior half of the shell, and on the 
columella in points, the posterior half, there being mere small pro- 
jections indicating the continuance of the inner edge of the colu- 
mellar groove, which extends the whole length of the columella, 
diminishing in depth in the middle of the shell, and deepening at 
the posterior end to form a part of the channel; margins slightly 
prominent, thick on the outer side only, not crenulated ; extremities 
of a light brown colour externally, much produced and thick; both 
the anterior are marginated and flattened externally; channels wide 
and protrude beyond the body of the shell; spire visible, deeply um- 
bilicated. 
Long, -86ths of an inch; wide, ;4° ths; high, ;4& ths.

The only specimen I have seen of this elegant shell is in my col- 
lection, and was brought to this country by Sir E. Belcher in the 
* Samarang.’ 
The only species with which this shell has any affinity is the Cyp. 
Sauli of Gaskoin ; and differs from it in the teeth being finer, and 
in being rather within the aperture, in having a columellar groove, 
in the absence of colour between the teeth, in being more ventricose, 
the wanting the characteristic dark blotch on the dorsum of Sauli, 
and difference of general coloration. 
I have thought it proper to add to this description the following 
note :— 
“My dear Sir,—I have carefully examined the little Cyprea 
which you left with me yesterday, and which you proposed to name 
Cyp. gracilis. It appears to me to he in perfect condition, and to
