There is considerable variation in the painting of this species, as stated in the original 

 description, some specimens being nearly entirely covered by the confluent flammules; the colour 

 varies in being in most cases reddish or brownish, but some specimens are of a bright crimson ; 

 however they agree in other respects, and it seems not to be doubtful, that they are one and 

 the same species. Melvill and Standen (Proc. Zool. Soc. 1901, p. 352) mention this species or 

 an allied form, as being uniformly pink, but more finely striate, from lat. i8°58'N., long. 70°45'E., 

 which shows that it is widely distributed. Pilsbry (1. c.) cites L. supragranosus Smith (Journ. 

 Linn. Soc. XII, p. 558, PI. 30, fig. 15) as a synonym; this figure is far more characteristic than 

 the original one, displaying the beaded sculpture of the superior whorls. The radula has about 

 the same appearance, as that of L. Carpenteri Pils. and L. sangarensis Schrenck, as figured 

 by Pilsbry. The rhachidian tooth (R) has a narrower projection above, I could not detect a 

 reflected cusp; the first lateral (i) has a rather large cusp, turned towards the outer side, with 

 3 or 4 denticles on the proximal side, the proximal uncini seem to have long, simple cusps, 

 only the first one (U) having an elongate body, with a simple narrowly reflected margin; the 

 distal uncini are more or less serrated on both sides.

The specimen from Stat. 1 74 is somewhat intermediate between the type and var. atrata 



Chemn., by the shorter laciniate appendages and more rounded aperture; the specimens fr9m 



Banda are very young.
