164 PANDA. 



Eggs large, white, hard-shelled. 



The special sculpture of the apex is generally worn off in adult 

 shells. The latter whorls are peculiarly variegated with chocolate 

 streaks and vermiculate lines on a yellow ground, and usually show 

 spiral bands of blotches. 



This genus is more nearly allied to Caryodes than to any other 

 group. These two Australian genera resemble Acavus, Helico- 

 phanta and Ampelita in their smooth jaws, unicuspid side teeth and 

 comparatively large eggs, but differ from them in the simple lip of 

 the shell, the presence of an appendicula, the insertion of the penis 

 retractor muscle on the main columellar retractor instead of on the 

 floor of the lung, and in the freedom of the ovotestis from the diges- 

 tive gland. The relationship between the Australian and the Indo- 

 Madecassine genera is therefore by no means intimate. Hedley, in 

 the important paper on these snails cited above, brought the Austra- 

 lian Liparns into the group he composes of Panda, Caryodes, Pedi- 

 nogyra and Anoglypta, but I am unable to follow his classification 

 to this extent. Liparns seems to me to belong to a distinct stock 

 I look to Otostomus, Placostylus, etc., for its kindred. 



The generic term Panda Heydeu, 1826, has not been used by re- 

 cent araneologists, and the definition given by Heyden in his 

 analytical table is not sufficient to rescue it from the status of a 

 nomen nudum. This antiquated use which can never be revived 

 should not prevent us from retaining Albers' name for the present 

 group.

The following genera, Macrocyclis, Solaropsi* and Chalepotaxis 

 are intercalated here in the Helix series provisionally, pending the 

 discovery of their true affinities by the examination of the internal 

 anatomy. The dentition of Macrocyclis, now for the first time made 

 known, is excessively peculiar, and comparable only to that of Heli- 

 cophanta and its allies. Of Solaropsis there is nothing known suffi- 

 cient to justify a guess at its affinities. Chulepotaxis has the
