462 Mr. E. A. Smith on Mollusca from the 



India, in 28 fath. ; off Mangalore, in 26-30 fath. ; off south 

 coast of Ceylon, 34 fath. ; Station 237, off Andaman Islands, 

 90 fath. 



Some variation exists among the series of specimens from 

 these localities ; those from off Honawar have the principal 

 spiral ridges dotted with red and only very slightly tubercu- 

 lated, whereas the examples from off Ceylon exhibit more 

 distinct tubercles and no dotting, but instead a very faint 

 brownish or reddish zone around the base of the body- whorl. 

 The apical portion of the spire is also more produced and the 

 sculpture of the first three normal whorls rather different. 

 They are more rounded and more finely cancellated. 



Murex Troschell, Lischke. 



Murex Troscheli, Lischke, Jap. Meeres-Conch. i. p. 41, pi. i. figs. 1,2; 

 ii. pp. 29, 164. 



Hab. Station 237, off Andaman Islands, 90 fath., stones. 



The largest specimen is 110 mm. in length. This is small 

 in comparison with the type from Nagasaki, yet the shell 

 appears to be mature. The spines also are rather longer 

 and more slender. The whorls are rufo-liueated, but the 

 spines are more slender and longer than as shown in Lischke's 

 iigures. Pilsbry* has pointed out a similar variation in 

 Japanese specimens.

 Murex niindunensis, Kobelt, Conch.-Cab. p. Ill, pi. xxxiv. fig. 8. 



Hab. Off Mangalore, Malabar coast, 26-30 fath. 

 One specimen only, rather young, 40 millim. in length. 

 The type was originally described from the Philippine Islands. 



Murex axicornis, Lamarck. 



Hab. Station 237, off Andaman Islands, 90 fath.; off 

 south coast of Ceylon, 34 fath. 



The Andaman examples are quite typical, as represented 

 by Kiener's figure (Icon. Coq. Viv. pi. xlii. figs. 2), but 

 those from Ceylon have shorter spines and generally three 

 instead of two nodulous costse between the varices.
