 lineation. Two specimens in the Museum collection, collected 

 in shallow water at the Andamans by Lieut. A. W. King 

 and Capt. Francis Hamilton^ have much brighter markings.

Hah, Off south coast of Ceylon, 34 fath. {' Investigator ') ; 

 Philippines (A. Ad.); Mauritius [RobiUard, in Brit. Mus.). 



The type of this species has been so overcleaned that the 

 very beautiful transverse sculpture is almost obliterated. It 

 consists of very numerous fine lirse, which are minutely 

 squamose and undulating. The two specimens from Ceylon 

 are of a delicate rose tint within the aperture and have a 

 series of flattened hollow spines upon the lower angle of the 

 body-whorl. They do not curve upwards like those above, 

 but stand out horizontally. The columella is coated with an 

 erect pink callus which unites with the labrum above. 



A specimen from Mauritius obtained by the late Victor 

 Hobillard is larger than the typical form and differs also in 

 being totally white, and the second keel upon the body-whorl 

 is ornamented with very numerous hollow, short, somewhat 

 upcurved spines. Also between this series and the squamose 

 crest at the base there is another series of smaller scale-like 

 spines. The fine, delicate, transverse sculpture which covers 

 the entire surface is of the same character as in the other 

 examples.

The single small example differs from the typical form in 

 having more distinct longitudinal plicpe and finer spiral stri;«, 

 the surface of the body-whorl being minutely reticulated. It 

 consists of four normal and two and a half apical whorls, the 

 latter being smooth and convex.
