On Conus (Cylinder) clytospira^ sp. n. 461 



coral differs by having narrower intercalicalar areas and mucli 

 stouter costo3 and frequently a raised calicular rim. Dr. Felix * 

 does not quote any coral under the name of 8ti/lina from the 

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

 coenia, which, however, is probably a Cyathophora.

Conns [Cylinder) clytosjyiraf, sp. n. 



C. testa magna, elegantissime attenuato-cylindrica, laivi, paruni 

 nitida, alba, brunueo-, castaneo- vel ochraceo-reticulata et macu- 

 lata, sicut in O. aidico vel C. episcopo, spira mire coiispicua ; 

 anfractibus sedecira, pulchre gradatis, infra suturas excavatis, 

 angulatis, deinde rectis, quorum novem supernis, sub lente 

 spiraliter scalptis, parvis, albidis, in medio angulatis, ad angulum 

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

 basin leniter producto, spiraliter iuterrupte bi- vel trifasciato ; 

 apertura angusta, contracta, labro teuui, supra, apud suturum, late 

 excavato ; columella recta. 



Long. 119, lat. 37 mm. (sp. maj.).

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

 long. 71° 30' to 71° 45' E., lat. 18° 43' N., adhering to the 

 submarine cable of the Eastern Telegraph Co. ; hauled up 

 from 45 fathoms [F. W. Tuivnsend, Esq.). 



The dredging of this remarkable textile cone undeniably 

 constitutes one of the most important dis'^overies of the kind 

 during the nineteenth century. It will rank amongst the 

 most select of a genus unusually distinguished in both 

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

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

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

 pattern of marking, it more assimilates C. auh'cus, L., or 

 episcopus, Hwass, being twice or thrice interruptedly spirally 

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

 lations enclosing oblong, obtusely triangular, or trapezoid 

 spaces of varying dimensions.
