Original description. — "Testa (pro genere) magna, sub- 

 cylindraceo-fusiformis, apicem versus cylindracea, albido-cornea, 

 unicolor, tenuis, subdiapbana, baud riraata, lineis elevatis vix 

 continuis et (prsesertim in anfractu ultimo, ubi remotiores fiunt) 

 oblique corrugata. Anfraetibus 10-12, sutura profunda et 

 minime crenata divisi ; apicales unice convexi, subsequales ; 

 caeteri convexi, et satis rapide creseentes ; penultimus major, 

 altior ; ultimus curvatus, verticaliter descendens, infra suturam

 of the peristome below. Hauley stated that it most closely re- 

 sembles the American C. epistomium, not a very happy comparison. 

 It certainly has much closer affinity with C. masoni, while it also
