190 PUSIA. 



T. NICOBARICA, Frauenfeld. PI. 56, fig. 612. 



Shell chocolate-brown, aperture also chocolate. H., 16 mill. 



Nicobar Isles. 

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



Dark chocolate-brown, more or less shouldered and distantly 

 longitudinally ribbed, sometimes crossed by revolving striae, 

 which become more distinct towards the base ; aperture chocolate 

 within. Length, *7 inch. 



Philippines ; Solomon Is. ; Australia ; Galapagos Is. 



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

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

 revolving sculpture except at the base. 



T. ZEBRINA, d'Orb. PL 56, figs. 630, 616. 



Smooth, dark chocolate with white longitudinal strigations. 



Length, 10-12 mill. 



Canary Islands. 



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. SEMEk, Reeve. PL 56, fig. 618. 



Smooth ; yellowish white and chestnut-brown in alternate 

 longitudinal narrow waved lines. Length, '5 inch. 



Philippines ; Polynesia : Sandwich hies. 



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

 flammulata, Pease, and T. zebrina, Garrett, both unfigured, will 

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

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

 shape. 



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



Finely granulated by decussating lines; dark chocolate, with 

 a narrow white superior band ; sometimes with a few white spots 

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



Paumotus and Society Islands. 



T. TRUNCULUS, Sowb. PL 56, fig. 619. 



Polished, ventricose, chestnut-brown. Length, -25 inch. 



Habitat unknown. 

 Described from a single specimen.
