PULMONATA 261 



(Mr Musson thinks it possible that L. megalodontes, described by 

 MM. Quoy and Gaimard in 1824, from Port Jackson, was this 

 species.) 



Amalia gagates, Draparnaud 



Reported from Ohaupo and Auckland by Mr Musson, and in 

 Hawke's Bay by Mr Colenso. Mr Suter states that this is a very 

 variable slug and quite a number of varieties can be distinguished. 



(Mr Musson thinks that Limax maurus, described by MM. Quoy 

 and Gaimard in 1824, from Port Jackson, was this species.) 



Amalia antipoda, Pfeiffer 



Amalia fuliginosa, Gould 



Amalia emarginata, Hutton 



All these three species, according to Mr Suter, have to be included 



in the gagates group, and are found in New Zealand, but he gives 



no localities for them. 



Hyalina crystallina, Miiller 

 Mr Suter records this species as occurring in Auckland. 



Hyalina alliaria. Miller 

 In conservatories and hot-houses ; Mr Suter does not record any 

 particular locality. 



Hyalina cellaria, Miiller 

 Mr Suter records it as occurring in gardens, meadows, etc., mostly 

 hiding under stones, at the Bay of Islands, Auckland, Napier, and 

 Wanganui. Mr Musson reports it from Auckland "under stones, 

 especially about the various volcanic mounts." 



Family Helicid^ 

 Helix aspersa, Miiller 



According to Mr Suter this species is common at most of the 

 sea-coast towns in New Zealand, where it is a great nuisance in 

 gardens. Writing to me in 1917, he informed me that it was much 

 more abundant in the north than it was at Christchurch, or farther 

 south. Mr Hutchison states that "this common garden snail is 

 greedily devoured by rats at Napier, while the next mentioned 

 species {H. kortensis}), which is also in the gardens, is not appreciated 

 by rats for some reason." A reference to this will be found at p. 83. 



Thrushes are very fond of this snail, which they carry to some 

 hard surface, where they break the shell with the bill and eat the 

 animal. Mr Musson, writing in 1890, says that examples from Opua 

 in the Bay of Islands are exceptionally thin-shelled, whilst shells
