profunde ae rude scrobiculatis ; apertures marginibus valde crenulatis ; 

 jissurd centralis antica, anguste et moderate incisd ; impressione 

 palliali postice rotundata, prope apicem lateraliter profunde insinuata, 

 antice prolongata ac gradatim latiori, ad terminationem truncata. 



Long. 5i Mil. —Diam. 4 Mil— Alt. 3 Mil. 



Very rare, — S. Prov. Ceylon. 



The nearest allied species to the above, that we know of, is E. crassi- 

 costata, Sow., it is, however, smaller, more elevated, not narrowed 

 anteriorly and the sculpture is somewhat different. 



Sub-emarginula Oldhamiana— N. S., Pi. XVII, Fig. 17. 



T. oblonga, conico-elevata, solida ; apice acuto, sub-centrali, sinis- 

 trorse incurvato ; superjicie externa virescenti, in parte anteriori 5-6 — 

 costata : costd media maxima, ad marginem aperturce valde prominentia 

 intus profunde canaliculata, in parte posteriori costis senis radiantibus 

 instructa; omninis plus minusve rugatis, atque costulis et striis numerosis 

 interpositis, versus apicem obsoletis notata ; superjicie interna albida ;

 insinuata. 



Long. 12 Mil— Diam. 7% Mil— Alt. 9 Mil. 



S. Prov. Ceylon, Scarce. 



The shell approaching nearest to the present species is S. Panhiensis, 

 Q. and Gr., from which it differs by the peculiar sinistral bend of the 

 apex, which is likewise more decidedly central by the greater pro- 

 duction of the anterior rib, forming a far more prominent canal, by the 

 great inequality of the radiating ribs, &c. 



Solarium impressum— N. S., Pi. XVII, Fig. 11. 



T. late-conica y depressiuscula, solidula, rufuld sen radiatim fusco 

 strigatd ; anfractibus quinis, depressis, suturd profunda junctiSj 

 spiraliter quatuor seu quin que striis minute granidosis notata, striis in- 

 crementi obliquis sub-distincte decussatis ; suturis impressis earumque 

 marginibus paulo incrassatis ac granulatis ; ultimo anfractu ad peri-

 margine incrassato granulatoque : granulis albidis, mediocriter promi-
