This shell may be recognised by its peculiarly narrow elongated 
form, the ligamental area describing a complete angle with the an- 
terior ; the ribs do not radiate from the umbones in a curved direc- 
tion, as in the preceding species, but are nearly straight. 
CarpiTa pistorta. Card. testd elongato-ovatd, valdé gibbosd, 
peculiariter distortd, luteolé ; costis duodecim aut plurimis, sub- 
squamosis, inferioribus planiusculis. 
Conch. Icon., Cardita, pl. 4. f.13. 
Hab. Red Sea; Riippell. 
There are several specimens of this curious species in Mr. Cu- 
ming’s collection, all singularly distorted in the same manner. 
Carpita Senecatensis. Card, testd oblonga, elongato-ovatd, 
Sulvd, epidermide fusca indutd ; costis quindecim sedecimve, squa- 
mosis, squamis incumbentibus. 
Conch. Icon., Cardita, pl. 4. f. 16. 
Le jéson? Adanson. 
Hab. Senegal. 
This shell, which I know to have been brought from Senegal by 
M. Rang, approaches nearer to the figure and description of Le 
jéson of Adanson than any that has been hitherto assigned to it. 
Carpira votucris. Card. testd elongatd, posticé valde gibbosd, 
angulatd, anticé brevi et coarctato-acuminatd ; viridescente albidd, 
postice mgrd nigroque maculatd; costis septemdecim, anticis 
planulatis, marginem versus evanidis; posticis angulatis, hinc 
alline obsoleté squamosis. 
Conch, Icon., Cardita, pl. 4. f. 20. 
Hab. ? 
Care should be taken not to confound this species with the young 
of the C. pectunculus. It is a solid well-developed shell, and never 
exceeds an inch to an inch and a half in length. 
Carpira cipposa. Card. testd ovato-oblongd, solidd, gibbosd ; 
albd, costis septemdecim, fusco-variegatis, transversim radiantibus, 
rotundatis, exiliter nodulosis. 
Conch, Icon., Cardita, pl. 4. f. 21. 
Hab. ? 
This is a solid gibbous shell, the anterior side of which is not so 
short as in most of the oblong species of the genus. 
Carpita niT1DA. Card, testd subquadrato-ovali, eburned, maculis 
cesis variegatd ; costis duabus vel tribus et viginti, posticis pre- 
cipué crenatis, interstitiis lineis cesiis angularibus ornatis. 
Conch. Icon., Cardita, pl. 6. f. 27. 
Var. B. Testa maculis rubidis. 
Hab. Misamis, isle of Mindanao, Philippines (found in sandy mud 
at the depth of twenty-five fathoms); Cuming. 
This pretty shell is remarkable on account of the posterior ribs 
being more strongly crenated than the anterior.
