XXXVl PROCEEDINGS OF THE 



Mr. James Steel exhibited a species of Cyclostoma, recently- 

 received by him, along with other shells, from Mr. John 

 Farquhar, Port Elizabeth, South Africa, a former member of 

 the Society. Mr. Steel stated that on examining the shell the 

 animal appeared to be still alive ; and when immersed in tepid 

 water it revived and crawled about, apparently little the worse 

 for its long imprisonment. 



Mr. Steel also made some remarks on the viviparous repro- 

 duction of Sphceriuin corneuin, L. On 20th April last, when 

 watching the siphons of several of these molluscs embedded in 

 sand at the bottom of his aquarium, he observed that one of 

 the largest was producing movements of an unusual character. 

 These could not proceed from fear, as the animal, when 

 alarmed, withdraws its siphons entirely within the shell. After 

 a number of expansions, contractions, and swayings to and 

 fro, of the siphons, which had now assumed a yellowish colour, 

 the true cause of the movement became apparent — a small shell 

 being suddenly shot out from the shorter or ejecting siphon. 

 Mr. Steel stated that Avhile this species is well known to be 

 ovo-viviparous, he had never seen the actual manner described 

 in which its young are launched into active life. 



The Chairman exhibited a fine specimen of HyiJiium Halleri, 

 L. fil., gathered by him on Ben Lawers on 13th inst. ; also, for 

 comparison, a fertile plant of the same species from the Swiss 

 Alps. He also showed specimens of the following Lichens, on 

 which he made some remarks, viz. : Spiloneina 2^(^i'(^doxii, 

 Cladonia jpu?i(7e?i.s, Rainal'uia farlnacea, Lecanora ventosa, and 

 Ox>egra2')lia citra, var. denlgraia.
