T. NICOBARICA, Frauenleld. 1*1. 56, fig. 612. 



Shell chocolate-brown. aperture also chocolate. II.. 16 mill. 



Nicobar Isle*. 

 T. FICULINA, Lam. PI. 56, figs. 613-615. 



Dark chocolate-brown, more or less shouldered :md distantly 

 longitudinally ribbed, sometimes crossed by revolving stria-. 

 which become more distinct towards the base; aperture chocolate 

 within. Length, '1 inch. 



Philippines; Solomon Is. ; Aiixtrnliii ; Galajtagos Is. 



I refer to this species T. gausapata, Reeve (iig. 614 . from the 

 Galapagos, and T. forticostata, Reeve (fig. 615); the latter without 

 revolving sculpture except at the base. 



T. ZEBRTNA, d'Orb. PI. 56, figs. 630, 616. 



Smooth, dark chocolate with white longitudinal strigntions. 

 Length, 10-12 mill. 



The type figured (fig. 630), is a narrower form than that 

 depicted by Sowerby ; the latter corresponds very well, however. 

 with a specimen before me, which I feel confident belongs to 

 this species. 



T. SEMEN, Reeve. PI. 56, fig. 618. 



Smooth; yellowish white and chestnut-brown in alternate 

 longitudinal narrow waved lines. Length, *5 inch. 



Philippines; Polynesia: S(tttt//r /'</> ./*/<- s. 



I add the localities following the Philippines, believing that T. 

 flammulata, Pease, and T. zebrina, Garrett, both un figured, will 

 prove to be synonymous with T. semen. It seems to he closely 

 allied to the typical form of T. zebrina, d'Orb., in coloring >uid 

 shape. 



T. PUTILLUS, Pease. PI. 56, fig. 617. 



Finely granulated by decussating lines; dark chocolate, with 

 a narrow white superior band; sometimes wit h a tew white spots 

 on the upper half of the shell. Length, *4 inch.
