HABITATIONS OF MOLLTJSKS. 1 7 



example, the first tinting in its Bulla form, is pale yellow, 

 with wavy bands ; in a second stage the waves become agglo- 

 merated, and leave the yellow in triangular flame-like spots ; 

 the teeth, meanwhile, are fully developed, and the sides are 

 thickened by means of a rich dark brown coating, thinly 

 spread over the dorsal surface, aud forming irregular reticu- 

 lations, as if by the admixture of some oily liqidd. 



A uniform pure, clear milky orange colour, designates the 

 first growth of the Scott's Cowry, C. Scottii. It then assumes 

 a bluish tinge, disposed in obscure bands, and begins to 

 show a few bright tortoise-shell brown blotches, which 

 rapidly accumulate, as seen in the adult, long before there 

 is any indication of teeth. This arrangement differs from 

 that of most Cowries, in which the teeth are cliiefly deve- 

 loped before the last layer of colouring matter is deposited. 



Lastly, the sides and base become thickened with an 

 extremely rich and dark brown coating of enamel, and the 

 extremities are compressed and turned upwards. This 

 curious shell was introduced to the knowledge of concholo- 

 gists by Mr. Broderip, to whom it was transmitted, about 

 fourteen years since, by the Eev. xlrchdeacon Scott, from the 

 island of Java, and since then several fine specimens have 

 been received from the Swan Eiver, New Holland.
