Genus Cyprcea. 203 



bright orange red. Length normal, i to i^ inch. Air. J. 

 M. Williams, of Liverpool, has a magnificent specimen, 

 3 J^: long., ij.4:iat. 



Native of all Eastern Seas. Abundant. 



{a) Williamsi {var. nov.). — Base suffused with orange 

 red, pattern on dorsal surface much blurred with fawn 

 colour. Length 2 in., lat. i]^. In JMr. Williams' coll. A 

 striking colour variety. 



{b) Caledotiica (Crosse). — Distorted var., with extremities 

 elongated, and unequally produced. Rare. New Cale- 

 donia, cf. Tryon, Man. Conch, pi. xiv. f 98. 



C. tessellata (Swb.). — Dorsal surface tawny, with three 

 broad bands ; sides squarely marked with black-brown 

 blotches bordered with white, and two chesnut-brown spots ; 

 base pale tawny and white, banded transversely ; teeth 

 orange ; mouth straight, narrow. Length i ^ inch. Rare. 

 Eastern Archipelago. New Zealand has been recorded, but 

 I doubt its occurrence there. Only very few specimens are 

 known otherwise than in a decorticated state. Those belone:- 

 ing to Miss Saul and the late J\Irs. De Burgh surpass all others. 



C. Childreiii (Gray). — Transversely ribbed throughout, 

 pale coloured, extremities angularly expanded below. This 

 last development does not occur in any other species. 

 Native of Polynesia. 



G. Adainso7iii (Gray). — To the unique peculiarities of 

 this species, as recent, I have already referred. As Mr. 

 Sowerby aptly observes, young specimens of Cyprcea 

 piistidata (L.) are allied to this. It is a native of the 

 Philippines and Mascarene Islands. 



C. irrorata (Solander). 



The prominence of the anterior columellar teeth dis- 

 tinguishes this species from any other, hence Dr. Gray created 

 a new genus for it, Naria (Descr. Cat, Cyp., p. 12, 1832). 

 Native of the Low Archipelago, Paumotus, etc. I think 

 there are several points of connection between this somewhat 

 isolated species and fimbriata, inicrodon, etc.
