TEREBRA. 37 



T. PLUMBEA, Quoy, PI. 11, fig. 7. 



Longitudinally plicate, plications straight ; fawn or lead-color, 

 white-banded at the suture ; sometimes a white band at the 

 periphery of the last whorl, below which the color is darker. 



Length, 1 inch. 



Moluccas, Philippines, China, Australia. 



The unfigured T. Bourguignati, Desh., is referred here by 

 Reeve. 



T. LISCHKEANA, Dunker. PI. 12, fig. 22. 



Distantly costate throughout, with an obsolete sutural band, 

 barely defined by a narrow sulcus, and punctations in the inter- 

 stices of the ribs ; yellowish, banded with chestnut, 



Length, 34 mill. 



Japan. 



Connects this group with those species having a sutural band, 

 and is evidently closely related to T. phimbea, etc. 



Subgenus EURYTA, H. and A. Adams. 



T. ACICULATA, Lam. PL 11, figs. 15-17. 



Spire and upper part of body-whorl plicate and shelving, 

 usually doubly nodose, the two rows separated by a sulcus on 

 the middle of the shelf, sometimes the lower row of nodules are 

 developed into spines, lower part of body-whorl with revolving 

 striae ; white, or broadly or narrowly banded with chocolate, or 

 uniform chocolate, or with close zigzag longitudinal markings. 



Length, '75-1 inch. 



Mazatlan, Cape St. Lucas, Panama, West Indies, 



? W. Coast of Africa, ? Mediterranean Sea. 



The American localities are certain, but the several records of 

 Mediterranean specimens refer to beach-worn shells, and it is 

 probable that they were introduced accidentally, and that the 

 species does not live there. The figures will show how variable 

 the shell is in its sculpture and coloring. It is by no means 

 certain that it is really the species intended by Lamarck, although 

 it is thus generally identified ; neither is its generic position
