The red-toothed Murex. Shell triangularly fusiform, 

 transversely obtusely ridged, with two approximating 

 tubercles between the varices ; three-varicose, varices 

 undulately laminated, erect, flowmg obliquely from 

 the apex, apertm'e small, lip conspicuously toothed 

 within ; cream-colom-ed, sparmgly stained here and 

 there with orange-brown, teeth red.

mb. — ? 



A tndy interesting species, quite distinct from any 

 hitherto described. It is of a triangular fusifonn struc- 

 tm'c, and each varix consists of an erect plaited lamina 

 flowing obliquely from the apex. The inner side of the 

 lip is strongly toothed, and the teeth being tipped with 

 red upon a milk-white ground have a very cliaste and 

 chai'acteristic appearance. Mr. Cuming possesses two 

 examples of this species, both in equally fine condition. 



Species 187. (Mus. Cuming.)

The spectre Murex. Shell erectly fusiform, transversely 

 ridged, ridges UTCgidai-, nodose and tuberculated, 

 sutures of the spire rather excavated ; thi'ee-varicose, 

 vai'ices thickened, frondose, fronds rather elongated, 

 branched and mmlcated, canal rather long ; yellowish, 

 fronds and ridges chesnnt-brown.

Hai. ? 



This new and somewhat remarkable species approximates 

 to the Murex paltna-rosee in foim, though perfectly distinct 

 tliroughout in its various details of character. Mi-. Cuming 

 possesses no information as to its locality, and has not 

 heard of any other specimen. 



Species 188. (Mus. Cuming.) 



Murex florifer. Mur. testd tr/gono-ovatd, subfusiformi, 

 transversim Uratd, liris subdistautibus, interstitiis sub- 

 til issime fmticidatis, funicuUs frondes super scabrosis, 

 tuberculo grandi elongato inter varices; trivaricosd, 

 varicibus pulcherrime frondosis, frondibus erectis, Jlori- 

 feris, muricatis; albicante,femgineo-fuscoplus mimisve

 catis intus extusque albis, apice rosacea. 



The flower-bearing Murex. Shell triangularly ovate, 

 somewhat fusiform, transversely ridged, ridges rather 

 distant, interstices very finely corded, cords scabrous 

 over the back of the fronds, with a large elongated 

 tubercle between the varices ; three-varicose, varices 

 very beautifidly frondose, fronds erect, floriferous, 

 muricated ; wliitish, more or less stained with rusty 

 brown, fronds darker brown, muricated extremities 

 of the fronds wliite within and without, apex pink. 



Eeeve, Pro. Zool. Soc. 1846. 



Hab. Hondm'as. 



A fine new species approximating in general appearance 

 to the Murex rvfus, from which it may easily be distin- 

 giushed by the forcible character of the ribs and tubercles, 

 by its white ground colour and pink apex, and the striking 

 effect which is produced by the white-tipped extremities 

 of the fronds. 



Species 24. (Mus. "RTiite). 



Murex megacerus. — A specimen from the collection 

 of H. H. White, Esq., illustrating a peculiar state of 

 this species (for the normal form of which see Plate VI.), 

 in which the fronds are of a short stunted gi'owtli, and 

 the body of the shell particularly stout and gibbous.
