18 TEREBRA. 



brown, usually nearly white on the sutural band, and with a 

 central white band on the body-whorl. Length, 1-25-2 inches. 

 Guinea (Humphreys); Sumatra (Cuming); 



Tasmania (Woods). 



T. Jukesii, Desh. (fig. 54), appears to me to be a synonym; 

 as are also T. addita, Desh. (fig. 55), T. geminata, Desh. (unfig- 

 ured), probably T. Kieneri, Des-h. (fig. 56), and T. gracilis, 

 Reeve, not Gray (fig. 57). 



T. LONGISCATA, Desh. PL 4, fig. 58. 



With a sutural band defined by a groove, strongly plicately 

 ribbed, the ribs rather angular, the interstices with elevated 

 revolving striae; livid fuscous gray. Length, 27 mill. 



Philippines, (Cuming). 

 T. TJSTULATA, Desh. PI. 4, fig. 59. 



Sutural band depressed, longitudinally ribbed ; pale chestnut 

 or whitish, the depressed band and lower half of the body-whorl 

 darker brown. Length, 32-38 mill. Tasmania. 



In coloring and form somewhat like the next species. 



T. GEMMULATA, Kiener. PL 4, figs. 61, 62. 



Shell longitudinally, narrowly, distantly plicate, plicae curved, 

 terminating in nodules below the groove of the sutural band, 

 the band also bearing a single row of nodules ; yellowish white, 

 the lower row of nodules white, with a rather broad white band 

 on the middle of the body-whorl, below which the whorl is 

 smooth and chestnut-colored. Length, 45 mill. Chili. 



Reeve, who saw the original specimen of the unfigured T. 

 Chilensis, Desh., adds it to the synonymy. Very probably T. 

 Patagonia, d'Orb. (fig. 62), should be added as a colorless 

 specimen. 



T. DISLOCATA, Say. PL 4, figs. 63-67, (',9 ; PL 12, fig. 31. 



Longitudinally plicate, spirally grooved ; sometimes the 

 grooves are only perceptible between the plic.ne, in others they 

 decussate the latter into granules; sutural band nodulous; colu- 

 mella recurved, ridged ; gray, brownish white or light yellowish, 

 with usually a white-banded periphery. Length, 25-35 mill. 



North Carolina to West Indies. 



The certain synonyms are T. rudis, Gray (fig. 69), T. Petiti.
