JSriDROMUS, 21 



In sculi^ture this species resembles T, disfortuSj but it is dis- 

 tinguished by the straight spire, the varices for apart instead of 

 in a continuous oblique series, and the revolving spots. 



T. testaceous^ Miivch (fig. 128), does not appear to differ in 

 any appreciable degree from the type ; it is the West Indian 

 manifestation of the species. T. comptus, Sowb. (fig. 15*1), from 

 China, is certainly the same species. 



T. NiTiDULUS, Sowb. PI. 14, figs. 130-132. 



Whorls smooth, polished, sometimes obsoletely granulated. 

 Light brown, belted and spotted with darker brown, sometimes 

 with longitudinal flame-like markings, sometimes with a white 

 median band. Varices twelve or fourteen, usually maculated 

 with brown. Length, I to 1'75 inches. 



Paumotus, Central Polynesia. 



Var. Ceylonensis, Sowb. PL 14, fig. 131. 



Decussating ribs more prominent, giving the surface a closely 



granulated ornamentation. 



Polynesia, Neio South Wales, Ceylon. 



In both forms the granules are equally prominent upon the 

 upper whorls of the spire, but in the smoother T. nifidulus this 

 nodulation is finally covered by or lost in a smooth enamelled 

 surface. T. Brazieri, Angas (fig. 132), inhabiting the coast of 

 New South Wales offers no important differential characters. 

 The lip and columella of the specimen described are tinged with 

 orange color. ^ 



T. RETicuLATUs, Blaiuv, PL 16, figs. 160, 161. 



Light brown, variously stained or banded with darker brown, 

 sometimes uniform dark brown. Length, 1 inch. 



Mediterranean Sea. 



T. pi/gmaeus^ Reeve (fig. 161), does not differ. Tlie Galapagos 

 Islands are given by Reeve as a locality for T, reticulata^, but 

 there is no su^bsequent confirmatory information. 

 T. LANCEOLATus, Meuke. PL 16, fig. 162. 



Yellowish white or flesh-color, more or less clouded and spotted 

 with brown ; varices eight or nine, bearing brown spots. 



Length, 1 inch. 



West Indies, under stones and pieces of coral, 



iu one or two feet water.
