436 On a supposed new Species of Land-Mollusk. 
portion above as in Damayantia Smithi and Microparmarion ; 
but the extreme contraction of the specimen may have 
produced this appearance. ‘This margin of the foot is quite 
pale in contrast to the very dark colour of the animal. 
The shell-lobes are continuous all round the margin of the 
shell, and would in life leave a more or less exposed apical 
area of the same; they are clearly divided into right and 
left lobes. There is a small right neck-lappet. 
Anatomy.—The visceral mass is globose and distinctly 
coiled about one and a half times, terminating bluntly. 
The jaw (fig. 8) is curved slightly, with a curvilinear 
cutting-edge. The lingual ribbon is long and of good breadth ; 
the central tooth is elongate, on a broad base, having a mode- 
rately long central point, with basal cusps on either side (as 
in Microparmarion pollonerai) ; the median teeth are also 
elongate, with a single cusp on the outer side. The laterals 
are narrow and elongate, with long, nearly equal, bicuspid 
points; they become short in length near the extreme margin 
and of very irregular blunt form (see figs. 9a-c). The teeth 
are arranged thus: +30—18—l1—18—30+. 
Generative Organs (figs. 5, 6, and 7).—The vas deferens 
is given off from the extreme free end of the male organ, 
there being no flagellum or kalc-sac; the position of the 
retractor muscle was not well made out, but appeared to be 
given off rather low down on the muscular sheath. The male 
organ is folded on itself in S-form, and contained a long 
spermatophore in process of formation (fig. 6), the short 
curved spines being observable. Neither the albumen-gland 
nor the hermaphrodite duct and gland were extracted, as I 
did not wish to destroy the visceral mass of the largest speci- 
men remaining, and in the small one I failed to find these 
parts. The spermatheca (fig. 5, sp.) was broken near the 
base, so whether it is ovoid or sessile or elongate is somewhat 
uncertain ; but, judging from the spermatophore, it is of the 
latter form. ‘The amatorial organ (D) was also incomplete at 
the free or posterior end, but fortunately the whole of the 
“‘sagitta’”’ was well preserved, and on this rested considerable 
interest ; it proved to be very long, rising from a funnel- 
shaped. base and terminating in a fine sharp point, being cut 
off obliquely like a pen, the total length being 2°6 millim. 
(figs. 7, 7a). It iscomparable with that of Parmarion pupil- 
laris of Java, figured by Heinrich Simroth (pl. vii. fig. 17) in 
his paperon this group of land-shells in ‘ Zoologische Ergebnisse 
einer Reise in Niederliindisch Ost-Indien,’ 1893. This form of 
the amatorial organ combined with the other characters 
places this species very satisfactorily in the genus Parmarion,
