188 PUS FA. 



\I T. AUREOLATA, Swainson. PL 55, figs. 600-606. 



Orange-brown, with a small white superior zone, and some- 

 times one or more thread-like inferior bands ; sometimes white 

 with an orange band below the suture and another at the base. 



Length, *75 inch. 



Philippines ; Polynesia. 



A very variable species in sculpture and coloration, and 

 therefore having a large synonymy. I have already, under T. 

 crocata, alluded to the fact that that species has usually been 

 identified with this ; it remains to figure the crocata of collectors 

 (fig. 600), which is a lemon-yellow variety of aureolata, with or 

 without a superior thread-like white band. T. multicostata, 

 Swains, (fig. 602), and T. crocea, Reeve (fig. 603), are examples 

 of shoulderless varieties of the type and of " crocata " respec- 

 tively ; they are both somewhat enlarged in the figures. In T. 

 venustula, Reeve (fig. 604), the revolving sculpture is darker 

 colored ; and in T.flavescens, Reeve (fig. 605), a portion of them 

 are so marked, giving the shell a bright, banded appearance. 

 T. affinis, Reeve (fig. 606), is also a synonym. 



T. PLICATISSIMA, Schroter. PI. 55, fig. 607. 



Grayish white, apex and base tinged with brown ; two dark 

 bands on the bod3^-whorl. Length, 20 mill. 



Habitat unknown. 



Perhaps a variety of T. aureolata. 



T. RUBRA, Swainson. PL 55, figs. 608, 609. 



Light pink and darker banded, or roseate with a light band, 

 sometimes interrupted by dark tints in the interstices of the 



ribs. Length, '25 inch. 



Paumotus ; New Zealand? 



The specimens before me, as well as the figures, show that it 

 is not an adult shell. Sowerby's fig. 393 (fig. 608) represents 

 the shell described by Garrett as T. exquisita ; it is at most, a 

 mere variety. 



T. BICOLOR, Garrett. 



An unfigured species, cinereous with'two rose-colored bands. 

 Length, 8 mill. 



Samoa and Paumotus Isles. 



Appears to be closely allied to T. rubra.
