Shell pear-shaped, anterior portion granulated, otherwise

457. MULTILINEATUS, Soiverlnj (f. 662). — C. testa turbinata, 

 flavescenti-fusca, lineis fuscis punctatis multi-cingulata, zona 

 lutescente subcentrali balteata, antice paulo attenuata, valide 

 costata, postice ItBvi, subacute angulata, ad angulum tuberculis 

 parviusculis coronata ; spira concavo-acuminata ; anfractus 2, 

 planato concavi, tuberculis parvis marginati, apertura albida. 

 Long. 40, lat. 20 mill. 



A turbinated species of rather solid structure, yellowish- 

 brown colour, encircled with numerous fine brown dotted 

 lines, and a sub-central belt of pale yellow ; spire rather con- 

 cavely acuminated, crowned with smallish tubercles, which 

 are made conspicuous by intermediate brown blotches. 



Hab. unknown. Specimen unique in Mr. Melvill's col- 

 lection. 



458. Thomasi, Sowerhy (f. 663). — C. testa elongata, solida, 

 albida vel pallide carnea, late pallide aurantio bifasciata, 

 antice leviter costata, deinde la?viuscula, minute cancellata ; 

 spira obtusa, vix elevata, sutura impressa ; anfractus planius- 

 culi, spiraliter minutissime striati, ultimus supra angulatus, 

 infra angulum aliquanto convexus, deinde prope rectus ; 

 apertura modica, supra et infra subeequaliter lata, fauce pallide 

 carnea. Long. 75, lat. 35 mill. 



Compared with G. ferehellumy to which this species is 

 allied, it is a smooth shell, with a shorter spire, and a more 

 decided angle. The species has been confounded with 

 Lamarck's C. pistinaica ; that of Reeve presenting a somiewhat 

 similar appearance is only a worn specimen of G. virgo. 



The type is in the collection of M. Thomas at Brest. 

 Other specimens I have seen are smaller, and have rather 

 more of a bluish or faint lilac tinge of colour. 



Hab. Red Sea.
