PLEUROTOMA.— Plate II. 



painting distributed in transverse lines (lineolis), and 

 not in any degree blotched or clouded, makes them agree 

 precisely with Lamarck's description. 



Species 12. (Mus. Stainforth.) 



Pleukotoma unedo. Pleur. testd angulato-turritd, fu- 

 siformi, striis longitudinalibus et transversis reticu- 

 lata, costellisque subdistantibus, subtilissime granu- 

 losis, cinctd; albd, spadiceo maculatd et longitudina- 

 liter nebulosd; anfractibus superni angulatis, peri- 

 pherid leviter bicarimtd ; canali vix elongato ; labro 

 sinu subcentrali. 



The strawberry Pleurotoma. Shell angularly tur- 

 rited, fusiform, reticulated with transverse and 

 longitudinal striae, and encircled with small, very 

 finely granulated, rather distant ribs ; white, spot- 

 ted and longitudinally clouded with reddish brown ; 

 whorls angulated at the upper part; periphery 

 lightly bicarinated ; canal rather long ; lip with the 

 sinus rather central. 



Valenciennes, MSS. Paris Museum. 



Kiener, Icon. pi. 14. f. 1. 



Hab. Seas of India, Kiener. 



This excellent species of Valenciennes cannot fail to 



be recognised by the characteristic figure with which 



our description is accompanied. 



Species 13. (Mus. Cuming.) 



Pleurotoma grandis. Pleur. testd longissimd, fusi- 

 formi, multicarinatd ; albd, maculis irregularibus fus- 

 cis marmoratd, strigis interdum subobsoletis longitu- 

 dinaliter nebulosd ; anfractibus convexis, carinarum 

 interstitiis imbricato-crispis ; canali elongato. 



The great Pleurotoma. Shell very long and fusi- 



form, many-keeled, white, marbled with irregula 

 dark spots and blotches, and longitudinally cloude 

 with streaks of the same colour, which are some 

 times nearly obsolete ; whorls convex, the inter 

 stices being finely crisped oi grained ; canal long. 



Gray, Griffith's Cuv. An. King. pi. 23. f. 1. 



Pleurotoma crispa, Kiener (not of Lamarck). 



Hab. Indian and Chinese Seas. 



Having perfectly identified the Pleurotoma crispa i 

 Lamarck, we gladly bear testimony to the correctness c 

 Mr. Gray's views in regard to this magnificent shel 

 which the first-named conchologist was evidently unac 

 quainted with. 



Species 14. (Mus. Cuming.) 



Pleurotoma australis. Pleur. testd turritd, fusiform 

 rubido-fulvd, costellis transversis, subtiliter gram, 

 losis, cinctd; anfractibus subventricosis, superne la 

 vibus, depressis ■. canali elongato, recto ; labro re 

 tundato, sinu lato, ab anfractu ultimo separato. 



The southern Pleurotoma. Shell turrited, fusiforn 

 reddish yellow, encircled with small, finely gram 

 lated transverse ribs ; whorls rather ventricosi 

 smooth and depressed at the upper part ; can. 

 long and straight ; lip rounded, separated from th 

 upper whorl by a broad sinus. 



De Roissy, Kiener Icon., pi. 4. f. 1. 



Murex australis, Chemnitz, Conch., vol. xi. pi. 19( 

 f. 1S27 and 1828. 



Hab. China. 



The delicate buff-coloured ribs which encircle thi 

 shell are much more strongly granulated in some spe 

 cimens than in others.
