1G8 TURRICtJLA. 



T. INTERMEDIA, Kieiier. PI. 50, fig. 430. 



Alternately zoned with ashy or chocolate-brown and white. 



Length, 2-2-5 inches. 



Moluccas. 



This species is entirely too intermediate for the satisfactory 

 separation of several other forms ; in its smoother varieties it 

 approaches very closely to chocolate-banded specimens of T. 

 vulpecula; its long, costate varieties are allied to T. costellaris, 

 Lam. and T. cinctella; its short, corrngated specimens are too 

 near to T. corrugata, Lam. (= 2\ I'uyosa^ Gmel.). 



T. CORRUGATA, Lam. PI. 50, figs. 429, 428, 427. 



Whitish or ash color, banded with chocolate. 



Length, 1'25-1*T5 inches. 



Indian Ocean, Philippines, Ifew Guine(t, Australia. 



It is too late to revive Gmelin's prior name (riigosa) for this 

 species. T. Jukesii, A. Ad. (fig. 428), is founded on juvenile 

 Australian specimens. T. fulvolij^ata, Sowh. (fig. 427), is very 

 close, if not identical. 



T. Berths, Sowb. PL 49, fig. 417. 



Ash or yellowish, encircled by narrow chocolate bands. 



Length, 32 mill. 



China Sea. 

 Appears to hold the same relation to T. corrvgata that 

 cinctella does to costellaris. 



T. Gruneri, Reeve. PI. 49, figs. 418, 419, 41G. 



White, more or less distinctly banded with ash, with a 



superior, and sometimes one or two inferior narrow chestnut 



revolving lines, shell sniootli between the longitudinal ribs. 



Length, •75-l'25 inches. 



Ceylon, Philippines, Polynesia. 



Resembles T. Be'rthae, but is distinguished by wanting its 

 revolving striae. T. cinctella, of which it might be suppposed 

 to be the young, has the earlier whorls closely ribbed, not 

 shouldered. It may be the young of a variety of 2\ jMcata, a 

 species from which it is only distinguished by the character of 

 its narrow bands. T. modesta, Pease (fig. 419), of which the 

 type specimen is now before me is certainly identical; and so is 

 T. Isevicoslata, Sowb. (fig. 416).
