MUREX.— Plate XXXIII. 



Reeve, Pro. Zool. Soc, 18i5. 

 Hah. ? 



A decidedly new species, reminding one at first sight of 

 the Murex Sinensis, but quite distinct on examination. The 

 entire shell is encircled with very close-set convex ridges, 

 each terminating on the varices in an erect frond, connected 

 together at the side so as to fonn a continuous laminated 

 frill extending from the sutiu'e to the base. 



Species 168. (Mus. Norris.) 



MuKEX CROCATDS. Mur. testa tnymo-fusiformi, trans- 

 versim Uraid, liris parvis, grauoso-squa)imtis, Uiber- 

 culo inter varices; irivaricosd, varicibus frondosis, 

 froiidiius obtuso-ramosis ; canali siibelon(jato, frondoso ; 

 fuscescente, frondibus ruhido-crocatis. 



The saffkon-tinged Murex. Shell triangularly fusi- 

 form, transversely ridged, ridges small, granosely sqa- 

 mate, with a tubercle between the varices ; three-va- 

 ricose, varices frondose, fronds obtusely branched ; 

 canal rather elongated, frondose; brownish, fronds 

 reddish saffron colour.

Eab. ? 



This might be regarded as a species of somewhat doubt- 

 ful character, but after careful comparison I am unable 

 to refer it to any hitherto described. The varices of fronds 

 in the specimen before me, fi-om the coUeotion of Thomas 

 Norris, Esq., which, with its operculum, is in excellent 

 condition, are of a bright scarlet saffron colour. 



Species 169. (Fig. Kiener.) 



Murex cariniferus. Mur. testa ovato-conicd, turUnatd; 

 longitudinaliter costatd, transversim striata; fulves- 

 cente ; spird acutd, spinis coronatd ; anfractibus con- 

 vexis, carinatis; striis siiblamellosis, decurrentibus ru- 

 ffosis ; aperturd albd ; labro dextro sulcata, dentic.ulato ; 

 catiali brevi ; columelld ba-si umbilicatd. 



The keeled Murex. Shell ovately conical, turbinated, 

 longitudinally ribbed, transversely striated ; yellowish, 

 spire sharp ; with sublaraellar, decurrent, wrinkled 

 striae ; apertiu'e white, right lip gi-ooved, denticulated ; 

 canal short ; columella umbdicated at the base.

Hob. ? 



This shell is unknown to me, but, rather than omit the 

 species, I have copied Kiener's figure and description. 



Species 170. (Mus. Ciuning.) 



Murex buxeus. Mvr. testa fusiformi-ovatd, anfractibus 

 superne subangulatis, multifariam miduloso-varicosis, 

 varicibus obtusis liratis, liris creberrimis minute rugo- 

 sis ; aperturd patuld, canali brevi ; lutescente-fuscd, 

 zonulis lutescente-albidis numerosis cingulatd, columelld 

 et apertures fame nived, prope viarginem, denticulatd. 



The box-wood Murex. Shell fusiformly ovate, whorls 

 a little angidated round the upper part, midtifiiriously 

 varicose, varices waved, obtuse, transversely ridged, 

 ridges very close-set, minutely wiinkled ; aperture 

 wide open, canal short ; yeUowish-brown, enciixled 

 with mmierous small yellowish white zones ; columella 

 and interior of the aperture snowy white, denticulated 

 near the margin.

 PoUia buxea, Sowerby. 



Hab. Iquiqui, Peru (found on a sandy bottom at the depth 

 of eighteen fathoms) ; Cimiing. 



A most aberrant form of the srenus. 



Species 171. (Mus. Grimer, Bremen.) 



Murex pudoricolor. Mur. ahbreviato-fusiformi, oblique 

 trigond, transversim liratd, liris singulis ttiberculis duo- 

 bus basem. versus evanidis inter varices, lined minutd ele- 

 vatd inter liras ; trivaricosd, varicibus rotuiidatis, pro- 

 minentibus, squamis frondibusque prototomis basem 

 versus pracipue pulcherrime ornatis; exiinie rubentc. 



The blush-coloured Murex. Shell abbreviatcly fusi- 

 form, obliquely triangidar, transversely ridged, each 

 ridge with two tubercles, fading towards the base of the 

 shell, between the varices, and a minute elevated line 

 between the ridges ; three-varicose, varices rounded, 

 prominent, beautifully ornamented with scales and, 

 especially towards the base, with small sprouting 

 fronds ; bright delicate blush-red. 



Reeve, Pro. Zool. Soc, 184.5. 



Kah. Island of St. Thomas, West Indies ; Gruner. 



To Ml'. Gruner, of Bremen in Germany, my thanks are 

 most justly due for the loan of this new and extremely in- 

 teresting shell. It reached me just at the moment in which 

 1 was arranging my last two plates of Miu'iccs for the ar- 

 tist ; and I take no little pleasure in recording, as a noble 

 example of disinterestedness in the pm-suit of science, the 

 cii'cumstance of his having forwarded it tlu'ough the post, 

 suspended at imminent risk from a letter, in order to be 

 in time for insertion : an offering the more acceptable, be- 

 cause coming from a gentleman to whom I had not the 

 honom' of being personally known.
