entirely absent, and the penis has two cxcal appendages, which 
have not been observed in Conulema.” I give Stoliczka’s descrip- 
tion in full :— 
“Shell conoidal, thin, consisting of many, usually spirally ribbed 
or striated whorls; base convex, narrowly or indistinctly umbili- 
cated ; margin of the aperture thin, not expanded, outer simple. 
“ Animal narrow, long, generally equal to twice the greater dia- 
meter of the shell; pedicles long, tentacles much shorter, lateral 
line distinct, the margin below it smooth; gland at the end of 
foot large, superseded by a distinct horn; sole grooved ; two shell 
and two dorsal lobes to the mantle, all of them small and with no 
separately produced appendages, but slightly extended on either 
end; genital organs with or without an amatorial gland; a single 
appendage to the penis, produced into the penis retractor, recepta- 
culum seminis terminating with a bulging end, attached to the 
anterior portion of the prostata. Jaw thin, transparent, smooth, 
indistinctly or finely concentrically striated in the middle. Radula 
large, consisting of numerous (about 100) transverse rows, each 
with very numerous (300 to above 400) teeth, a few median teeth 
being conspicuously larger than the laterals, which are narrow, 
pectiniform, and very gradually decreasing in width.”

‘Formerly indicated as H. turbiniformis, mihi, in the ‘ Journal 
of the Asiatic Society of Calcutta.’ This name being used by Pfeiffer 
for another species, I have altered it for one of nearly similar signi- 
fication. H.infula occurred to me in 18385 on the leaves of trees 
and shrubs at the two places above noted. The animal has a caudal 
protuberance like Nanina, but no expansion of the mantle, and is
