MELVILL AND STANDEN : MARINE MOLLUSCA OF MADRAS. 37 



Conus (Lithoconus) virgO L. — Typical. Red Sea, East Africa, 

 Ceylon, Philippines, New Caledonia, Polynesia. 



Conus (Chelyconus) adansoni Lm. — According to Tryon, this 

 is but a variety of C. mediterraneus Hwass, " Shell more cylindrical." 

 It occurs likewise at Senegal. 



Conus (Cylinder) omaria Hwass. — Typical. Red Sea, Ceylon, 

 Philippines, Australia, Polynesia. 



Conus (Hermes) nussatella L. — Small, typically marked 

 specimens. Red Sea, East Africa, Ceylon, Java, Philippines, North 

 Australia, Lifu, Polynesia. 



Pleurotoma amicta E. Sm.* — Also common at Bombay. 

 Described originally from the Sandwich Islands. 



Pleurotoma (Surcula) tornata Dillw. — Generally known as 

 P. javana L. ; but that author's description is of a ribbed shell, better 

 known as P. nodi/era Lm., which this is not. One example, and that 

 a fine albino. Also from Java and East Indies. 



Pleurotoma (Turris) marmorata Lm.— Five, in good condi- 

 tion. Red Sea, Malacca, Japan, Australia, Polynesia. 



Pleurotoma (Turris) variegata Kien. — Two, well marked.

Pleurotoma (Gemmula) ceylonica E. Sm. — Characteristic, 

 but imperfect at the mouth. 



Pleurotoma (Gemmula) multiseriata E. Sm. — Two shells, 

 both in fine condition, and better than the type. There is consider- 

 able resemblance between this and one or two of the Eocene species 

 from Barton. Ceylon, Persian Gulf, China Sea. 



Pleurotoma (Drillia) crenularis Lm. — Four, all typical. 

 Bombay, Tranquebar, Singapore, Australia. 



Pleurotoma (Drillia) major Gr. — Three specimens of a very 

 distinct species, the habitat of which has, apparently, hitherto been 

 unknown. 



Pleurotoma (Drillia) nodifera Pease. — Many, all typical and 

 fine. Recorded from the Sandwich Islands. 



Pleurotoma (Drillia) regia Beck. — Similar to Lifu examples. 

 Also recorded from Amboina and Moluccas. 



Pleurotoma (Drillia) tayloriana Rv. — This, and P. major Gr., 

 are perhaps only forms of P . crenularis, but are very distinct, and 

 always recognizable. Bombay, Tranquebar, Singapore, Australia. 



Pleurotoma (Clavus) echinata Lm. — Fine, quite typical. 

 West Coast of Africa.
