30 LAND AND FRESHWATER 
Stoliczka (l. c. p. 237) thus describes the animal :— 
“The animal is of a dull whitish colour ; the larger warts of the 
body, often possessing a pink tinge, are arranged in oblique rows ; 
the pedicles are grey, and this colour also extends over a part of 
the back ; ridge of the posterior part of the foot ashy grey; mantle- 
lobes light, or sometimes pinkish grey ; inner part of mantle, form- 
ing the pulmonary sac, with spots and stripes of dark pigment, 
giving the shell, when the animal is retracted, a spotted appearance. 
“ The mantle-lobes [Pl. VIII. fig. 2 ¢] are very slightly extensible ; 
those covering the shell are somewhat thickened near their margins, 
the left shell-lobe being slightly reflected over the edge of the outer 
lip, so as to just cover it. The right dorsal lobe is much larger than 
the left, which is represented by a mere thickened rim. 
“ The general anatomy of the digestive and nervous organs and 
of the muscular system is exactly as in Rotula. 
“ The generative organs [fig. 2 | have a large and long uterus ; 
the terminal swollen end of the seminal receptacle is imbedded in a 
soft tissue at the anterior end of the prostata; vas deferens short 
and extremely thin, widened before it enters the penis, the ex- 
panded portion being filled with a granular colouring pigment, in 
which, however, no calcareous particles were discernible. The 
penis is rather thick, posteriorly prolonged and attached by thin 
muscles to near the end of the prostata. The amatorial gland [D] 
is a very strong, tough, twisted tube, enclosing a pointed flagel- 
“The jaw [fig. 2d] is semicircular, slightly projecting in the 
centre of the concave edge, smooth, about the median part indis- 
tinctly and very finely concentrically striated. .... The radula 
[fig. 2¢] is very large, consisting of about 100, nearly straight or 
slightly undulating transverse rows. In a full-grown specimen I 
counted 405 teeth in a row, the formula being 
2004+2.1.2+4+200= 
202.1. 202 
and the total number of teeth about 40,000. 
‘‘The four median teeth are conspicuously larger than those fol- 
lowing on either side; all have a sharp pointed cusp at the anterior 
end. The centre tooth has besides two smaller cusps at each side 
and is symmetrical; the following are gradually more and more 
turned on either the right or left side, and the smaller cusps are 
therefore developed only on one side; the last lateral tooth is 
styliform. 
“The shell of Conulema attegia is subject to a large amount of 
variation. The original specimen described from Tenasserim was a 
thin horny shell, and probably not quite mature. Young shells 
have the periphery always very sharply carinated, and the spiral 
ribs or striz on the whorls, as well as on the somewhat inflated 
base, are distinct. Specimens which live on foliage or other kind 
of vegetation on low land retain the thin horny structure of their 
shells, even when fullgrown ; hut the spiral striation of the whorls
