Reeve, but niiieli Inrger, uari'ower, paler in color, and si^mcwlmt 



curved before. Tiengtli, 20 niill.

 T. KiiAtissi, Dimker-. 



All unlliiuicd species, reseinliliiig the pieceding, sonu'wiuif, 

 and also recalling the narrow variety of 7'. inicrozoniaH. It is 

 found in the .Fapanese seas. 



T. OROCATA, [jam. PI. 55, ligs. 5115-597. 



Reddish orange or yellowish brown, with a superior narrow 

 white band. Length. -75 -1-25 inch. 



PMllppiaes ; Polynesia. 



The type ligured by Kieiier, lig. 595, is even larger than the 

 size given in Lamarck's description — which is, length one and a 

 quarter inches. I have some doul)t whether the shell usually 

 identified with T. arocata^ and which is common enough in 

 cabinets, is really that species, for it is always much smaller and 

 less shouldered — sometimes without any superior angle on the 

 whorls. If this identification is correct, a large synonymy must 

 be added (p)rincipally on account of inconstant coloration), 

 including T. aareoJata. venuHtula^fiavesceni^. etc. I prefer to let 

 cToeata stand as a somewhat doubtfnl form, and include the 

 others under the name of T. aureolata. T. concinna, Reeve (fig. 

 597), is a smaller shell, varA-^iug only in the interstices of the 

 revolving ridges being darker colored. 



T. PYRAMiDALis, Reeve. PI. 55, fig. 508. 



Yellowish or orange-broAvn, with a white superior zone. 



Length, 1 "25-1 '5 inches. 



Isle of Annaa, Paumotus Group. 



Garrett obtained a specimen which is white with two orange- 

 yellow bands. The spire is more elegated and less angular than 

 in T. crocata : the ribs much more curved and more roughly 

 tuberculated. This is the aui-antia of Swainson, not Gmelin, 

 and Garrett proposes to revive that name ; Gmelin 's species 

 being a true Mitra and Turricula now generally accepted as a 

 distinct genns : in common parlance the Turricuh^, however, will 

 probably continue to be referred to as Mitrae, so that some con- 

 fusion might arise from reinstating T. aurantia.
