T. AUREoLATA, Swaiiisoii. PI. 55, tigs. >)00-HOfi. 



Orange-brown, with a small white superior zone. mihI some- 

 times one oi- niort' thread-like inferior bands ; sometimes white 

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



Length, "75 inch. 



P7iilipj)inet< ; 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 tliat 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 baud. T. mKlticostafn, 

 Swains, (tig. ()02), and T. crocea. Reeve (tig. 003), are examples 

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

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

 venustula,, Reeve (fig. (504), the revolving sculpture is darker 

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

 are so marked, giving the shell a l)right, banded appearance. 

 T. affiniSj Reeve (tig. 606), is also a synonym. 



T. PLK^ATissiMA, Schroter. PL 55, tig. 607. 



Grayish white, apex and base tinged with l)rowii ; two dark 



bands on the body- whorl. Length, 20 mill. 



Habitat iniknowii. 

 Perhaps a variety of T. aureolata. 



T. RUBRA, Swainson. PI. 55, tigs. 608, (>0t). 



Light pink and darker banded, or roseate witli a liglit band, 

 sometimes interrupted by dark tints in the interstices of the 



ribs. Length, -25 inch. 



Paumotus ; Neir Zealand? 



The specimens l)efore 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. BiooLOR, Garrett. 



An unfignred species, cinereous witii two rose-colored ])ands. 



Length, 8 mill. 



Samoa and Paumotiis Isles. 



Appears to be closely allied to T. rubra.
