Hab. ? 



• The Murex bipinnatus approaches the Murex davus in general form, 



. but the detail of structure and sculpture is distinct throughout. The 



iį spire exhibits a mass of prominent nodules, each whorl taking the 



\ form of a heptagon, with as many as seven on its circumference. 



I The lašt two varices are ornamented with a handsome laminated 



frill structure. 



MuREX SiNENSis. MuT. testd elongato-ovatd, subfusiformi, tenui, 

 spirte suturis subimpressis ; anfractibus transversim Uratis et stri- 

 atis, inter varices nodiferis ; trifariam varicosd, varicibus fron- 

 dosis,/rondibus regularibus, curvatis, pulcherrbnė floi-idis , inciso- 

 serratis ; albicante, fusco tinctd, lineis transversis fuscis ; labro 

 . infra medium fortiter erecto-dentato. 



Hab. China. 



This species appears to have been confounded for some time past 

 Avith the young of the Murex ramosus or elongatus. It is uniformly 

 of a thin structure, and the fronds are of a delicate open flowery 

 growth.

Hab. ? 



This shell might easily be mistaken for an accidental stunted 



grovvth of the Murex palma-rosa, were it not for the eonstancy and 



marked peculiarity of its characters. The fronds are short and some- 



what erect, with a row of small fronds sprouting up at their base ;
