STRUCTURE AND AFFINITIES OF PANDA ATOMATA. — 1IEDLEY. 27 
affinities. Albers’ classification, “ Die ITeliceen,” p. 229, though 
more correct, is not in accordance with the views of the writer, ? 
who has recently enjoyed an opportunity of studying this,, 
interesting creature alive in the recesses of its native forests. 
The following is the first record of the soft parts of this-, 
snail. The animal so resembles the figure of Cary odes dufresni , 
appearing in the P.L.S., N. S* W. (2) vi. PL iii. f. 1. that this, 
sketch would almost as well represent the former as the latter 
species. Colour ; a pale oehreous yellow becoming redder on the 
head and tentacles ; a dark brownish-black dorsal stripe extends 
from between the tentacles to the mantle, a similar but fainter 
stripe extends on either side along the facial groove from the lips 
to the mantle ; sole of foot ashy-blue ; mantle ashy-blue shot with 
oehreous yellow. Some snails are paler and some darker than the. 
one described. Total length 70 mm., muzzle projecting 25 mm. 
in front, tail projecting 7 mm. behind the shell when crawling; 
tentacles 15 mm. long, bases 5 mm. apart; measured just in 
advance of the shell, the body is 15 mm. wide and 12 mm. high. 
Tentacles gradually tapering to one-third of the diameter of their 
bases, clad with fine longitudinal granulations; ocular bulbs 
asymmetrical, more swollen on the lower distal side, eye superior 
central in position. Two ill-defined grooves start from the 
mantle and enclose a series of rugae which compose the dark, 
median dorsal colour-band mentioned above; anteriorly these 
grooves are lost in the reticulations around the bases of the 
tentacles. From the median line, reticulating grooves extending 
outwards and downwards, intersect a series of prominent long 
narrow tubercles, from six to ten of which intervene between the 
dorsal band and the facial groove. The tail is rather flat and 
sharply pointed ; the sides and tail are covered by flat, irregular 
polygonal tubercles which become smaller on approaching the 
tail. On emerging from its shell, atomala has a habit of 
spreading the margin of the foot into a wide, fiat flange. I note 
that the left side of the mantle developes no rudimentary mantle 
lobes as in lfadra . When extended, the shell is carried slightly 
obliquely, the apex being a little to the right of the tail; when 
retracted, the animal does not usually shrink further back than 
the aperture, to which no epiphragm was observed. 
The living snails were colhcted by Dr. Oox and the writer in 
tolerable abundance in a “cedar-brush” adjoining Mr. Ashford’s 
estate on Sparke’s Creek, near Scone, N.S.W. Their habit was 
to nestle beneath decaying logs or in drifts of fallen leaves, where 
they would occur singly or by twos and threes ; one was taken in 
the act of ascending a tree a few feet from the ground. Specimens 
were obtained (April 1892) in all stages of growth. Dr. Cox 
informs me that on other occasions he has found this species 
to lay large, white, hard-shelled eggs.
