the Ceylon
Branch of the Royal Asiatic Society, in which he has described fifty-six
species,--thirty-three belonging to the genus Doris alone--gives ample

_List of Ceylon Shells._

The arrangement here adopted is a modified Lamarckian one, very similar
to that used by Reeve and Sowerby, and by MR. HANLEY, in his
_Illustrated Catalogue of Recent Shells_.[1]

[Footnote 1: Below will be found a general reference to the Works or
Papers in which are given descriptive notices of the shells contained
in the following list; the names of the authors (in full or abbreviated)
being, as usual, annexed to each species.
