in colouring. The type is in the collection of the lady after 

 whom it is named. Several other specimens have been found, 

 but it is still extremely rare.

454. BoCKi, Soirerhy (f. G59). — C. testa turbinata, pallide 

 lutea, luteo-fusco transversim multifasciata, et longltudinaliter 

 strigata, hie illic nigro-fusco radiata; spira breviuscula albida, 

 promiscue luteo strigata, ad apicera leviter prominente ; an- 

 fractus leviter concavi, serie tuberculorum coronati, ultimus 

 supra angulatus, ad angulum tuberculis grandibus coronatus,

Eesembling the Chinese C. sulcatus in form, but a much 

 smoother shell, and more deeply coloured ; the chief difference 

 however is in the crown; G. sulcatus being characterised by a 

 sharp undulating keel at the angle, forming a raised ridge 

 round the depressed whorls of the spire ; while in C. Bocki 

 the crown is formed of slightly angular nodules, between 

 which the angle is rounded. 



Hab. Amboyna. Specimen in Mr. Melvill's collection. 



455. BACCATUS, Sowerhij (f. 660). — C. testa abbreviato- 

 turbinata, turgidula, minutissime decussata, conspicue seriatim 

 granulata, albida, maculis aurantiacis grandibus trifasciata ; 

 spira parum elevata ; anfractus concavi fere la3ves, ultimus 

 biangulatus. Long. 23, maj. lat. 15 mill. 



An interesting little species, delicately painted, and cha- 

 racterised by rows of neat gem-like granules. The double 

 angle at the top of the body whorl is peculiar, but this may 

 possibly prove to be an accident, and not a specific character, 



Hab. unknown. Coll, Melvill.
