Since resorting to M. Kiener's figure of this species 



in despair of being able to identify it, I have had the 



good fortune to receive a specimen from the valuable 



collection of my .very worthy friend Thomas Lombe 



Taylor, Esq., of Norfolk.

Pleurotoma Nov„ Zelandi_. Pleur. testd acumi- 

 nato-turritd, subfusiformi, albido-rosed ; anfractibus

Pleurotoma rosea, Quoy, Voy. de 1' Astrolabe, pi. 35. 

 f. 10 and 11. 



Hab. New Zealand ; Quoy. 



Mr. Sowerby appears to have been the first to make 



use of the specific title of rosea (vide Plate VI. Species 



43.). 



Species 144. (Mus. Delessert.) 



Pleurotoma striata. Pleur. testd obeso-oblongd, acti- 

 minatd, pallide olivaceo-flavd; anfractibus longitudi- 

 naliter costatis, costis subobliqtiis, prominentibus , 

 transversim striatis, striis exilibus, numerosis ; colu- 

 mella superne callosd ; labro simplici, sinu lato. 



The striated Pleurotoma. Shell stoutly oblong, acu- 

 minated, pale olive-yellow ; whorls longitudinallj 

 ribbed, ribs rather oblique and prominent ; trans 

 versely striated, stria? very fine and numerous ; co 

 lumella thickened at the upper part; lip simple

Kiener, Iconographie, p. 36. pi. 14. f. 2. 



This appears to be a very distinct species ; it may b> 

 chiefly recognised by the determined character of tb 

 ribs. 



Species 145. (Mus. Stainforth.) 

 Pleurotoma carbonari a. Pleur. testd turritd, carbo 

 narid ; anfractibus prope suturas depressis, Icevibui

 columelld callositate superne munitd ; canali brevi 

 sinu latissimo, prof undo.

Hab. ? 



All the specimens I have seen of this dark Melani; 

 like species have the apex either decorticated or broke 

 away, an indication of their living in brackish water.
