PLEUEOTOMA.— Plate XXI. 



A pretty deep pink shell encircled with a bright chesnut 

 band, which is lighter at intervals where it passes over the 

 tubercles. 



Species 181. (Mus. nob.) 



Pleurotoma punctata. Pleur. testa fusiform/', anfrac- 

 tibus supertte valde depressis, lavigatis, carina, parvd 

 prope suturam, medio nodosis, infra granulatis ; canali 

 longiusculo ; sinu latiusculo; atbidd, rubido-fusco punc- 

 tata, prmcipue super carinam et inter nodos. 



The dotted Pleurotoma. Shell fusiform, whorls very 

 much depressed at the upper part, smooth, with a 

 small keel near the suture, nodose in the middle, gra- 

 nulated beneath ; canal rather long ; sinus rather 

 broad ; whitish, dotted with reddish-brown, especially 

 upon the keel and between the nodules.

Hai. ? 



This species approaches the typical form of the genus, 

 but is not referable to any of those yet described. 



Species 182. (Mus. nob.) 



Pleurotoma lanceolata. Pleur. testa lanceolatd, an- 

 fraclibus superne concerns, tuberculis ohliguis plus 

 minusve obsoletis medio omalis, Iambus, anfractu ultimo 

 minutissime granulato ; canali breviusculo ; aurantio- 

 fuscescente, tuberculis albidis. 



The lanceolate Pleurotoma. Shell lanceolate, whorls 

 concave round the upper part, ornamented in the 

 middle with oblique tubercles which are more or less 

 obsolete, smooth, last whorl very minutely granulated ; 

 canal rather short ; pale orange-brown, the tubercles 

 whitish. 



Reeve, Pro. Zool. Soc, 1845. 



Hab. ? 



This is not an adult shell, nor can the sinus be determined 

 on account of a fracture in the lip ; the species is neverthe- 

 less well distinguished from any hitherto noticed. 



Species 183. (Mus. Cuming.) 



Pleurotoma sacra. Pleur. testa ovatd, solidiusculd, ba- 

 sem versus subgibbosd ; anfraclibus superne depressis, 

 nodulorum serie unicd prope suturam, infra lougi/udi- 

 naliter granoso-costatis, transversim minute Ural 'is ; ca- 



nali brevissimo, sinu lato ; albidd, anfractu ultimo 

 fascia pallide fuscescente cingulatd. 



The solemn Pleurotoma. Shell ovate, rather solid, 

 somewhat gibbous towards the base, whorls depressed 

 at the upper part, with a single row of nodules near 

 the suture, longitudinally granosely ribbed beneath, 

 transversely minutely ridged ; canal very short, sinus 

 broad ; whitish, last whorl encircled with a pale Light 

 brown band. 



Peeve, Pro. Zool. Soc, 1845. 



Hab. ? 



The whorls of this shell are peculiarly gibbous round 

 the middle. 



Species 184. (Mus. nob.) 



Pleurotoma rubinicolor. Pleur. testa ovatd, subn-n- 

 tricosd, anfraclibus superne angulato-depressis, ad ungu- 

 ium obtuso-nodosis, noclis subpUcato-confluentibus, lesvi- 

 bus, ultimo basem versus obsolete striato ; canali bre- 

 vissimo ; aurantio-rufd, nodis per angulum niveis. 



The red-coloured Pleurotoma. Shell ovate, rather 

 ventricose, whorls angularly depressed at the upper 

 part, obtusely noduled at the angle, nodules some- 

 what plicately confluent ; smooth, last whorl obso- 

 letely striated ; canal very short ; orange red, nodides 

 along the angle snowy white.

Hab. ? " 



Well distinguished from any other species by its form 

 and peculiar style of painting. 



Species 185. (Mus. Cuming.) 



Pleurotoma nux. Pleur. testa ovatd, subpyramidali, an- 

 fraclibus convexis, superne leviter concavis, irftimo sub- 

 gibboso ; canali brevissimo, truncate ; sinu latiuscnlo ; 

 rubido-castaned, columella et aperture fauce albis. 



The nut Pleurotoma. Shell ovate, somewhat pyrami- 

 dal, whorls convex, slightly concave at the upper part, 

 last whorl rather gibbous; canal very short, trun- 

 cated ; sinus rather broad ; reddish-chesnut, columella 

 and interior of the aperture white. 



Reeve, Pro. Zool. Soc, 1845. 



Hab. Cape of Good Hope. 



A smooth dark reddish brown shell with no variety of 

 sculpture.
