170 COSTELLARIA. 



T. CUMINGII, Reeve. PL 50, figs. 435-439. 



Longitudinal ribs rude, rounded ; crossed by revolving rounded 

 riblets, the interstices between the latter deeply impressed except 

 where they cross the ribs. Whitish, sometimes spotted with 

 brown, and usually brown-banded in the middle. 



Length, 11 '5 inches. 



Ceylon, Philippines, Polynesia, Mauritius. 



Besides a copy of Reeve's type (fig. 435), I give one from 

 Sowerby's Thesaurus (fig. 436), which corresponds more nearly 

 with the richly-colored specimens lineated with brown, found by 

 Mr. Garrett at the Paumotus Isles. With this species must be 

 united T. clathrata. Reeve (fig. 438), and T. dimidiate, Sowb. 

 (fig. 437), which is now admitted by him to be a synonym. 



T. rugosa, Sowb. (fig. 439), of which only a single specimen is 

 known, appears to differ only in the somewhat greater promi- 

 nence of the revolving sculpture on the body-whorl. I think it is 

 the same species : if it is, then its priority of publication must 

 cause the adoption of its name instead of that of Gumingii. 



T. MONTROUZIERI, Souv. PI. 50, fig. 440. 



Yellowish brown, lighter at the angle of the shoulder. 



Length, 1 inch. 



New Caledonia. 

 T. LUCIDA, Reeve. PI. 50, fig. 441. 



Ribs swollen at the upper part, transversely elegantly ridged ; 

 transparent white. Length, '66 inch. 



Philippines. 

 T. NODULIFERA, A. Ad. PI. 50, fig. 442. 



The figure given by Sowerby is white, but Mr. E. A. Smith 

 describes a specimen from the Solomon Islands as pale pinkish 

 with white ribs, the aperture orange. Length, 11-5 mill. 



It possibly equals T. lucida. 



T. MODESTA, Reeve. PI. 50, fig. 443. 



White, slightly tinged with pink towards the base, aperture 

 pink. Length, -8 inch. 



Isle of Ticao, Philippines. 



"A very chaste pink-white shell, with a highly relieved latticed 

 sculpture."
