Of a bright, warm straw-colour, variously freckled with 

 chestnut spots and dots. 



Species 65. (Fig. a, b, Mus. Cuming.) 



Chondropoma ternatum. Chond. testdsubawpliterpro- 

 fumU umbilicatd, globoso-lnrbinatd, stramined, liya- 

 lind, riifo-fitsco maculatd, siituris angiisie cauaUcu- 

 latis, aiifractibus declivi-rotutidatis, spiraliter tetiui- 

 liratis, ultimo subinflato, aperturd circulari, labro late 

 pliiuo-fimbriato. 



The ternate Chondropoma. Shell rather largely 

 deeply umbilicated, globosely turbinated, straw- 

 colour, hyaline, spotted with reddish-brown, sutures 

 narrowly channelled, whorls slopingly rounded, spi- 

 rally finely ridged, last whorl rather inflated, aper- 

 ture cu'cular, lip broadly flatly fimbriated. 



Cijclostoina turnatuiu, Gould, MS. in ilus. Cuming. 



Hab. ? 



Very like the preceding species in sculpture and colour- 

 ing, but a more inflatetlly convoluted hyaline shell, with 

 the lip broadly fimbriated. 



Species 66. (Mus. Cuming.) 



Chondropoma solare. Chond. testd imperforatd, co- 

 nico-turritd, pnrpiireo-ciiiered, albo tenuifunicidatd, 

 anfractibus convci-is, spiraliter aitgiiste liratis, iiiter- 



stiliis longitudinaliter minute crenulatis, aperturd 

 ovato-circulari, labro latissime plicato-Jimbriato. 



The solar Chondropoma. Shell imperforate, cuni- 

 cally turreted, purple-ash, finely corded with white, 

 whorls convex, spirally nari'owly ridged, interstices 

 longitudinally minutely crcnulated, aperture ovately 

 circular, lip encircled with a very broad puckered 

 frill. 



Pfeiffer, MS. in Mus. Cuming. 



Ilab. ? 



This fine species, lately named by Dr. Pfeiffer, is finely 

 corded thi'oughout witli white ridges upon a purple-ash 

 ground, which is most exquisitely crenulated in ihe oppo- 

 site direction. The bold plated frill encircling the aper- 

 ture, except on the side where it would be obstructed by 

 the body whorl, is an equally striking charactei-. 



Species 67. (Fig. «, b, Mus. Cuming.) 



Chondropoma sagittiferum. Chond. testd umbilicatd, 

 ovato-turritd, sordidti ulbd, fernigineo-fusco longitiidi- 

 naliter iiudatd, anfractibus declivi-coiivexis, liris plano- 

 obtusis densissime reticulatis ; aperturd pyriforiiii- 

 ovatd, labro plus minus Jimhriato. 



The arrow-bearing Chondropoma. Shell umbili- 

 cated, ovately turreted, dull white, longitudinally 

 waved with rust-brown, whorls slopingly convex, 

 very densely reticulated with flatly obtuse ridges, 

 apertiu'c pyriformly ovate, lip more or less fimbriated.

 Cistiila ? sagittifera, Pfeift'er. 



JIab. Jamaica. 



The sculpture of this shell is a close obtuse reticulation, 

 with the interstices mere punctures. 



Species 68. (Mus. Cuming.)

 catd, oblongo-conicd, sordide Jtavesceute, sub/iyiilind, 

 pone aperturam sparse fusco-fasciatd, anfractibus de- 

 clivi-convexis, spiraliter elevalo-striatis ; aperturd 

 ovato-circulari, labro lulissiuii concavo-fimbriato.
