(Plate L.) 



The shells treated upon in this paper form part of a series 

 recently presented to the British Museum by Capt. L. Worthington 

 Winner, by whom they were dredged whilst stationed at the Andaman 

 Islands. All, with one or two exceptions, were obtained at the depth 

 of a few fathoms off Port Blair. The collection contains about half 

 a dozen new forms, the most interesting of which is a remarkable 

 shell which I have provisionally located in the genus Fusus. 

 After each species I have quoted the locality first assigned to it, and 

 others have been added on the authority of specimens in the Museum, 

 in order to give at a glance the known geographical distribution, 

 which is always interesting, and calculated to assist materially in the 

 identification of the various forms. 



1. Conus andamanensis. (Plate L. figs. 1, la.) 



Shell subcylindrical, with somewhat convex lateral outlines, pale 

 pinkish white, marked irregularly with small brown spots and Hues, 

 and covered with a very thin, smooth, greyish epidermis : spire 

 elevated concave, composed of ten whorls ; the two nuclear ones 

 subglobose, semidiaphanous, smooth, the four following slightly 

 turreted, and the rest obliquely planulated, spirally sculptured with 

 two to three fine revolving striae ; the markings on the spire are in 

 the form of short brown lines following a radiating direction (that is, 

 across the whorls) : the last whorl has the upper angle rather 

 obtuse, and is sulcated at the base with about twelve transverse 

 grooves. Aperture rather narrowed above, and a little widened to- 

 wards the base, white within. Lip thin, with a small sinuation at 

 the upper extremity. Length 22 mill., diam. 11. 



This pretty little species, which I am unable to place as the young 

 state of any larger form, is remarkable on account of the fine brown 

 dots or lines, which are irregularly scattered over its surface of a
