142 FAUNISTIC NOTES 



CRUSTACEA 

 Trichoniscus (Philougria} roseus. No. 12 Green-house, 1896. 



MOLLUSCS 



Physa acuta and P. hypnorum are stated to have been taken 

 in the Lily House in 1902. 



A foreign species of Bulimus was discovered on the 

 Water-lilies in the tank by Mr. G. D. Carpenter, and 

 from the same source Sir Ray Lankester used to obtain 

 Paludina for his embryological researches, including among 

 others the demonstration of the coincidence of blastopore 

 and anus. 



Sir Ray Lankester also informs me that he once procured 

 thirty great orange-coloured Slugs, Arion rufus from Germany, 

 and tried to keep them in a large cucumber-frame, but they 

 all escaped into the Garden, unfortunately without establish- 

 ing themselves there ! 



The Roman Snail, Helix pomatia, was to be found in the 

 Garden some years ago (A. H. C.). It is so no longer, for the 

 gardeners, who in virtue of their manhood " have dominion 

 over every living thing that moveth upon the earth," do not 

 pause to consider Cowper's teaching : 



An inadvertent step may crush the snail 

 That crawls at evening in the public path ; 

 Yet he that has humanity, forewarned, 

 Will tread aside, and let the reptile live. 



WORMS 

 (For a list of the Earthworms^ see p. 260.) 



That most interesting terrestrial Flat-worm (Planarian) 

 Bipalium kewense^ first discovered crawling on damp surfaces 

 in Kew Gardens, turned up in the Banbury Road, in 

 J. T. Filsell's Orchid House, in 1898, but I can find no certain 

 record of its having appeared in the Botanic Garden.
