MELYILL & SYKES: MAPaNE SHELLS FROM THE ANDAMAKS. 43 



93. Terebka eaphanxtla, Lam. We think this distinct from the 

 forms of 1\ Se7iegalensis, Lam. The only specimen in this collection is 

 of a dark shining brown variety, most attractive in beauty. It is a rare 

 inhabitant of the East Indian Archipelago, and a welcome addition to 

 the Andamanese Fauna. 



94. Terebea solid a, Desh. This, which may be a variety of 

 T. hastata, has been hitherto reported from Japan. 



95. Teeebea nitida, Hinds, var. sictodes,^ n.var. PI. Ill, Fig. 8. 



T. testa aciculata, attenuata, nitida, Itete fulvo-brunnea, anfractibus 

 18, apicalibus?, cseteris longitudinaliter arete costatis, costis lajvibus, 

 nitidis, interstitiis planis, Isevissimis, sed apud medium transversim 

 profunde regulariter punctatis, ultimo anfractu recto, paullum 

 producto, apertura angusta, obliqua, labro extus tenui, simplici. 

 Long. 37, lat. 6 mm. 



A most interesting form, of a pleasing fulvous-brown colour, shining, 

 longitudinally ribbed, both ribs and interstices quite smooth. Each 

 interstice has a single, deep, ovate puncture placed exactly midway 

 between the ribs and a little above the middle of the whorl. The 

 mouth is narrow, oblique, outer lip simple. The shell is eighteen- 

 whorled, very long and attenuate. The typical form of T. nitida is 

 almost white, with a faint tinge of lilac ; the apex is brownish. 



It is not improbable that T. cernica, Sby., from the Mauritius, is 

 also a variety of T. nitida. 



96. Teeebba straminea. Gray. A beautiful species, nearly allied 

 to 2\ monilis, Quoy & Gaim., on the one hand, and T. Balylonia, Lam., 

 on the other. The revolving strife and sulcations are beautifully 

 chased. When originally described in 1834, its habitat was considered 

 to be China, but extending to the Philippine Islands ; it now, how- 

 ever, proves to have a much wider geographical range. Both the 

 varieties T. acuta, Desh., and T. circinata, Desh., occur in the 

 Andamans. 



97. Terebra TiGRiNA, Gmelin. Beautiful examples, with operculum ; 

 but not showing any variation. A not uncommon Polynesian form : 

 we have recently seen it from the Loyalty Islands, New Caledonia. 



98. Terebka TRICOLOR, Sby. The yellow and carnation hue of 

 this pretty shell, with orange-red transverse lines, always serves to 

 distinguish it. It is not a common species. 



We have not attempted to divide the species of Terehra into 

 subgenera. The genus as a whole is a natural one, and we think 

 the divisions proposed to some extent artificial and needless. 



99. Solarium (Heliacus) dorsuosum. Hinds. A small shell, 

 apparently having a wide range. 



100. *' CoNus Andamanensis, Smith. An endemic little species. 



' (Ti/cuciSTjy, ' like a gherkin or cucumber.'
