I go H. B. Preston -. New species of Shells. [Vol. II, 



Allied to T. jenestrata, Hinds'; the transverse costae in the 

 present species are, however, closer together and not so coarse, the 

 spiral strife are also more numerous and not so well defined. 



Terebra unicoloy, sp. nov. 



Shell rather bluntly, elongately subulate, pale brownish orange 

 throughout ; remaining whorls 17, sculptured with a coarse infra- 

 sutural spiral crenate rib and five smaller spiral crenate ribs, the 

 interstices finely punctate ; aperture smaU ; columella recurved, 

 twisted ; canal short. 



Altitude . . • • 44 mm. 



Diam., major .. ' .. 7"25 ,, 



Aperture, alt. . . . . 6 ,, 



,, diam. . . 2'5 ,, 



Habitat — Andaman Islands. 



Allied to T. alhouiarginata, Desh., of which species I was at first, 

 inclined to consider it a variety, but its much blunter form, lack^ of 

 white edging to the whorls, coarser ribbing and finer punctation 

 lead me to think that it is specificahy distinct. 



Conns cdwardi, sp. nov. 



Shell turbinate, coronate, white, the upper whorls tesselated 

 with reddish brown ; the body whorl painted with four irregular 

 bands of bright reddish brown, the first much interrupted, the 

 intervening spaces streaked, tesselated and very indistinctly lined 

 with the same colour, faintly and regularly spirally striate ; spire 

 bluntly exserted ; interior of shell whitish, except at the base where 

 the reddish brown colouring is again apparent. 



Altitude . . . • 58 mm. 



Diam., major . . . . 28 ,, 



Aperture, alt, .. .. 49*5 ,, 



,, diam., minor . . 3 ,, 

 Habitat — Andaman Islands. 



Allied to Conus zonatus, Hwass ; it is, however, narrower and 

 less pyriform in shape, the spire is more exserted and the beautiful 

 reddish brown colouring readily distinguishes it from that well- 

 known species, in which the bands are purplish gray, and which is 

 so conspicuously lined with orange. 



Pleurotoma rimata, sp. nov. 



Shell turreted, yellowish brown ; whorls 11, the upper bearing 

 two spiral ridges between which is a row of coarse tubercles, 

 the intervening spaces sculptured with minute spiral and trans- 

 verse striae, the last whorl bearing five spiral lirse in addition to the
