MOLLUSCA OF INDIA. O17 
erepuscular.” Which may be a Parmacella, for there is no mention of 
the mucous pore. It is thus described in J. A. 8. B. 1849, p. 649 ; 
Arch. Naturg. 1852, p. 239 :—-‘ Animal bright gamboge-yellow, 
with four tentacles; posterior portion of the body behind the shell 
keeled ; shield strengthened internally with a shovel-shaped shell of 
a pearly or nacreous appearance, obtuse and globose at the apex, 
with a deep sinus, covered with a thin, transparent epidermis, 
transversely wrinkled by the lines of growth; colour white. 
Length 4, breadth about 4 of an inch.” 
Since writing the above I have happily received from Mr. M. 
Ogle, of the Indian Survey Department, who has sent me many 
shells from time to time, a slug-like form from the ranges on the 
Kandahar and Khelat frontier. This, from its keeled foot and 
shovel-shaped shell, cannot be anything else than this species, 
rutellum of Hutton, or one allied to it. It has no mucous pore ; 
it thus belongs to a group very distinct from Girasia. I have ex- 
amined the animal; it is unlike any of the eastern forms with which 
I am acquainted, and must be put in a new genus, which I propose 
to call Canpawaria, which I shall describe and figure later on. 
2. Girasia extranea, Férussac. Habitat unknown. Hist. Moll. ii. 
96.—“ Shell a thin horny pellicle, without any appearance of a 
spire. Mantle with a circular opening showing the brownish 
pellicle. Foot truncated behind, with a subcaudal pore the whole 
length of the truncation, with a very strong keel above to the back 
of the shield. The body encased in a nick in the back.” This 
agrees well with the form of the typical species. 
3. Girasia? problematica, Férussac, Hist. Moll. ii. p.96. Habitat 
unknown.—“ Mantle much produced, forming a collar in front. 
Body convex and raised behind. Foot small, short. Shell yellow, 
convex externally, concave internally, like a half egg-shell.”—Des- 
hayes, from Ferussac’s figure. This is very unlike the type. 
About the same period Fischer described the genus Parmarion, 
in the Actes Soc. Linn. Bordeaux, 1855. (The paper bears 
date June 1855, the part March 1856; so that Mr. Gray’s 
title would have priority.) Fischer places in it the following 
species :— 
infumatus, Fér. (Gray, Fig. Moll. plate 286. fig. 1). Hab? 
(Placed in Drusia, by Gray.) 
extraneus, Fér. (Gray, Fig. Moll. plate 286. fig. 2). Hab. ? 
rangianus, Fér. Bourbon and Madagascar. (Placed in Drusia? 
by Gray.) 
problematicus, Fér. (Gray, Fig. Moll. plate 286. fig. 4). Hab. ? 
From the drawing of infumatus by Férussac, one would be led 
to suppose that the shell is very rudimentary, and entirely eon- 
cealed by the mantle-lobes. Unfortunately the habitat of this 
species and extraneus is unknown and never likely to be satisfac- 
torily established. 
Dr. Semper, in his fine work, Reis. Arch. Phil. 1870, p. 9, 
places in Parmarion two specimens, pupillaris, Humbert (proble- 
matica, Fér.?), from Java, and eatraneus, Fér., obtained through
