An interesting small species, dredged by Professor 

 Edward Forbes at the above-mentioned locality. 



anfractibus superne obscure carinatis, infra carinam 

 concavis, medio conspicue oblique nodosis, transversim

 beneath the keel, conspicuously obliquely noduled 

 round the middle, transversely finely striated through- 

 out, stria; rather elevated, granulated ; sinus rather 

 large, base truncated ; yellowish white, transverse

Hob. ? 



I dedicate this interesting new species with a great deal 

 of pleasure to its worthy possessor Thos. Lombe Taylor, 

 Esq., a gentleman whose zeal in collecting shells is only 

 equalled by his extreme readiness to communicate speci- 

 mens, the investigation of which is at all likely to afford 

 information. 



Species 366. (Mus. Taylor.) 

 l'Lia'ROTOMA Tayloriana. Pleur. testa elougato-turritd, 



Species 369. (Mus. Taylor.) 



Pleurotoma ustulata. Pleur. testa abbreviato-fusiformi, 

 spira suturis snbprofundis ; anfractibus superne cana- 

 liculatis, medio conspicue bicarinatis, infra carinas 

 tenuiliratis ; sinu amplo ; canali breviuscnlo ; pallide 

 ustulata, anfractuum parte snpremd juxta suturam ru- 

 hido-fusco maculato-tiuctd. 



The scorched Pleurotoma. Shell shortly fusiform, 

 sutures of the spire rather deep ; whorls canaliculated 

 round the upper part, conspicuously two-keeled 

 round the middle, encircled with fine ridges beneath 

 the keels ; sinus large ; canal rather short ; pale 

 burnt brown, upper edge of the whorls next the su- 

 ture stained with spots of reddish-brown. 



Hob. ? 



This is another new and well-defined sjjecies for which 

 I am indebted to my esteemed friend T. L. Taylor, Esq. 

 The three interesting new species from that gentleman's 

 cabinet described and figured in this plate, though coming 

 at the eleventh hour, form a most acceptable termination 

 to this very long and tedious monograph. 



April 1846.
