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 sevripture 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 apertures valde prominenti, 

 intus profunde canaliculata, in parte posteriori eostis senis radiantibus 

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

 interpositis, versus apicem oosoletis notata ; superficie interna albida ;

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

 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, depressiuscula, solidula, rufuld sew radiatim fusco 

 strigatd ; anfractibus quinis, depressis, suturd profunda junctis, 

 spiraliter quatuor seu quinque striis minute granulosis notata, striis in- 

 crementi obliquis sub-distincte decussatis ; suturis impressis earumque 

 marginibus paulo incrassatis ac granulatis ; ultimo anfractu ad peri- 

 pheriam sub-carinato, ad basin convexo, profunde umbilicato ; umbilici 

 margine incrassato granulatoque : granulis albidis, mediocriter promi- 

 nentias ; apertura oblique quadrangulari marginibus simplicibus in- 

 structa.
