184 rLEUROTOMARIA. 



breviuscula ; columella superne rectiusculo deinde arcuata, 

 oblique elongate: 38 alt. x 48 lat. ; fiss. 20xl| mil. — The 

 type specimen of this species, shown in Plate II., recently 

 drawn, was found in a basket of lobsters, taken in the waters 

 between Marie Galante and the Island of the Dominique, and 

 was occupied by a hermit-crab. It was obtained for France 

 by M. Bernardi, but passed through several French hands, till 

 Mr. Damon, of Southampton, having acquired it, sold it to 

 the late Mrs. De Burgh, of whose beautiful collection it still 

 forms a part. It is the smallest of the four species now 

 known. Its sculpture is exquisite. The part of the fissure 

 remaining open is nearly a quarter of the circumference of 

 the last whorl. The apex is gracefully acuminated and the 

 suture is deep. 



2. Betbichi, f. 7, 8, Hilgendorf. — Elevatim conica, pal- 

 lide flavida, rubro flammulata solida ; anfractibus subdistanter 

 liris planatim subnodosis spiraliter cinctis, leviter convexis ; 

 sutura crenata, fascia cicatricosa inframediana ; disco basali 

 sulcato, versus medium IsBvigato, medio profunde infundibu- 

 lato ; apertura subovata, columella crassa, nacrea rectiuscida 

 infra arcuata cum margine basali aperturse confluent! : 82 

 mil. alt. X 83 lat. — The incomplete state of the aperture pre- 

 vents the fissure being accurately described, but from the 

 band-mark it seems to have been broad, and from other 

 appearances most likely to have been short. The centre of 

 the basal disc has a funnel-shaped hollow which might be 

 described as an umbilicus. The characters are seen in our 

 figure, copied from Dr. E. von Marten's ' Conchologische 

 Mittheilungen.' The unique specimen is from Japan. It is 

 the next smallest in size to P. Quoyana, but much larger. 



3. Adansoniana, f. 3, 4, Crosse, 1801. — Conica acuminata 

 profunde umbilicata, pallide rosaceo-fulva, flammulis macu- 

 lisque rubescentibus irregulariter picta ; anfractibus 11-12 

 supra medium obtuse angulatis, spiraliter liris granulosis 

 spiralibus, fascie basali magis conspicuis, et striis concentricis 

 decussatis ; cicatrice fissurse supramediana, lata, tenuiter ar- 

 cuatim striata ; fissura lata elongata ; apertura fere quadran- 

 gulari, vivide nacrea; disco basali subconvexa : 74 alt. x 82 

 lat. ; fiss. 70 X 2 mil. — The sculpture consists of numerous 

 granulated spiral threads, crossed by oblique striae ; it is 

 stronger at the basal surface and under the suture of the
