var. subcingulata, nov. 



Distinguished from L. scahra and all its allies by the rounded 

 thin columella which is not in the least thickened or appressed ; 

 the coloration is much as in L. scahra var. punctata, Phil. ; 

 the^ spiral ribbing more numerous and less raised than in 

 typical L. filosa. 



Long. 17, diam. 10 mil.

Agree exactly with original figures ; Mr. H. F. Blanford 

 also possesses four, probably typical (?) specimens from Tenas- 

 serim [Mergui ?].

ain 



Perhaps the most beautiful marine shell, when living, that 

 I have ever seen. The colours fade terribly after death; it is 

 most difficult to get perfect specimens and it appears to be 

 remarkably local. The variety can be distinguished by its 

 extreme fragility, by the much less developed peripheral keel, 

 less obsolete sculpture, and especially by the more rounded 

 columellar margin at base; it varies wonderfully in colour, 

 from a beautiful rose to the typical straw colour, oftentimes 

 marbled or striped. I had separated the above from the 

 following specimens as a distinct sub- variety, when I found two 

 tubes in Dr. Stoliczka's collection, marked " $ and $ " ; that 

 marked ? contained six of the preceding and one of the fol- 

 lowing specimens [the last probably inserted erroneously ?] ; 

 the other tube marked J contained eight, all of the following form!
