TEREBRA. 17 



white band below the middle of the whorls, and whitish on and 

 just below the band. Length, 3-4 inches. 



China, Japan. 



Too close!}' allied to T. duplicata, Lam. The white band, 

 however, is rather broader, the plications narrower, sharp-edged 

 and partially obsolete on the band which is somewhat concave. 

 T. evoluta, Deshayes (fig. 47), described from a single specimen 

 in the Cumingian Collection, appears to be only a slight varia- 

 tion of the typical form ; another variety is T. Bernardii, Desh. 

 (fig. 48). 



T. DUPLICATA, Linn. PL 4, figs. 49-51. 



Flatly longitudinally ribbed, divided by an impressed line 

 below the sutures, forming a sutural band ; grayish or blush- 

 white to chestnut or chocolate, with a single narrow median 

 white band. Length, 2'5-3*5 inches. 



Moluccas, Singapore, Zanzibar, Madagascar, 



China to Viti Islands, etc. 

 T. Eee^ei, Deshaj'es (fig. 50;, is a colorless example. 



Yar. JJAMARCKII, Kiener. Fig. 51. 



The white band filleted with chestnut or purplish spots in a 

 single somewhat distant series. 



T. ANOMALA, Gray. PL 12, fig. 36. 



Smooth, polished, whorls plicate above, divided by an im- 

 pressed, punctate line near the suture; cinereous or fawn-color, 

 lighter on the sutural band, with a whitish band on the periphery. 



Length, 1*5 inches. 



Singapore, 7 fms. (Cum ing). 



Reeve confounded this species with the shell which he erro- 

 neously refers to aciculina, Lam., and which must stand as 

 wirulina, Reeve Lamarck's shell being a synonym of T. 

 dnerea, Born. The -present species is readily distinguished by 

 its sutural band. 



T. SPECTABILIS, Hinds. PL 4, figs. 52-57. 



Ribs distant, thin, subnodulous above and below a deep 

 groove which divides oft' a sutural band ; leaden or chestnut-
