On Conus (Cjliuder) clytospira, sp. n. 4G1 



coral differs by having narrower intercalicular areas and mucli 

 stouter costai and frequently a raised calicular rim. Dr. Felix * 

 does not quote any coral under the name of Sti/lina from the 

 Neocomian of Puebla ; but he describes a species as a Crypto- 

 coeni'a, which, however, is probably a Cyathophora.

 lata, sicut iu C. aulico vel C. episcopo, spira mire conspicua ; 

 anfractibus eedecim, pulchre gradatis, iufra suturas excavatis, 

 angulatis, deinde rectis, quorum novem supernis, sub lente 

 Bpiraliter scalptis, parvis, albidis, in medio angulatis, ad angulura 

 minute albi-nodulosis, ultimo aufractu pergracili, attenuate, ad 

 basin leniter producto, spiraliter interrupte bi- vel trifasciato ;

Hah. Arabian Sea, about 125 miles W.S.W. of Bombay, 

 long. 71° 30' to 71° 45' E., lat. 1S° 43' N., adhering to the 

 submarine cable of tiie Eastern Telegraph Co. ; hauled up 

 from 45 fathoms {F. IF. Townsend, Esq.). 



Tiie dredging of this remarkable textile cone undeniably 

 constitutes one of the most important discoveries of the kind 

 during the nineteenth century. It will rank amongst the 

 most select of a genus uimsually distinguished in both 

 form, texture, and coloration. In form, indeed, it is more 

 gracefully attenuate than its nearest ally, C. gloria-mar in ^ 

 Chemn., but in the latter characteristic, viz. coloration and 

 pattern of marking, it more assimilates (J. auJicus^ L., or 

 episcopus, Ilwass, being twice or thrice inteiruptedly spirally 

 banded on the last whorl, with coarse, widely spread reticu- 

 lations enclosing oblong, obtusely triangular, or trapezoid 

 spaces of varying dimensions.
