rORALLIOPHlLA. 207 



C. PORPHYROLEUCA, (-rosse. PL 66, figs. 369, 370.

Length, -88 inch. 



Tahiti. 



C. BULBIFORMIS, Conrad. PI. 65, figs. 357, 359, 360. 



Colors as in last species. The spire is more raised and the 

 shell is longitudinally ribbed. Length, 1-1-25 inches. 



Sandwich Isles to Tahiti, New Caledonia. 



( 1 . ELABORATA, H. a i id A. Adams. 



Shell ovate-conic ; solid, white, obliquely longitudinally plicate; 

 with revolving scabrous line, the scales of which are produced 

 and aculeate on each side, making the lira? biserrate. 



Sandwich Islands. 



Not figured ; evidently allied to C. bulbiformis. 



C. CALLAOENSIS, Gray. PI. 65, fig. 358. 



Light brownish white, without and within. Length, 1 inch. 



Gallapagos Isles, Peru. 



In form not unlike C. neritmdm, but has not the violet aperture 

 of that species, and is very faintly longitudinally nodose or 

 ribbed. 



C. GALEA. Chemn. PL 65, figs. 363, 362, 364. 



Shell yellowish white externally ; white, frequently tinged with 

 light yellow or light pink within the aperture. 



Length, 1-2 inches. 



Philippines.^ Central Pacific, West Indies. 



There can be no doubt of the specific identity. of the West 

 Indian with the Pacific shells ; of the former, I have before me 

 numerous specimens from St. Thomas, St. Croix, Bahamas and 

 Nicaragua. Chemnitz is not a binomial author, and according 

 to priority his name should yield to C. abbreviata. Lam., but it 

 has become so well known that its displacement would become 

 an injury to science. 



The young shell is Murex plicata, Wood ; and in this stage the 

 spire is conically elevated, the shoulder of the body-whorl more 

 distinct, below which the shell rapidly narrows to the base, the 

 umbilicus and its ridge scarcely defined.
