SOME NOTES ON RUMINA DECOLLATA LINN. 



BY C. W. JOHNSON. 



In March, 1897, Mr. T. L. Montgomery, Librarian of the Wagner 

 Free Institute of Science, brought from Bermuda some live specimens 

 of Rumina decollata. Some of these were given to my young friend, 

 Mr. H. S. Viereck, while the others were placed among some plants 

 kept in the museum of the Institute. Mr. Viereck placed them in 

 his yard in Philadelphia. They flourished and increased greatly in 

 numbers during the summer and survived the winter of 1897-98. 

 During the summer of 1898 they again thrived, but in the following 

 spring only dead shells could be found ; the blizzard of February, 1899, 

 was probably too severe for them. 



The specimens kept at the Institute are still vigorous, but produced 

 only one brood. Through the kindness of Mr. Viereck, I obtained, 

 in September, some live European Helices, including Helicella erice- 

 tonim, collected by his sister in Germany. An old aquarium was 

 quickly turned into a snailery ; thinking that the Rumina would en- 

 joy new quarters, a few were also placed in the snailery. A day or 

 so afterwards, when giving the Helices some cabbage leaves, I noticed 

 that the Rumina seemed very close to the Helicella. On picking up 

 a specimen, I was greatly surprised to find the former greedily de- 

 vouring the poor ericetorum. I could not blame the carnivorous fel- 

 low, for it was probably the first "square meal " it had had since it 

 was taken from its island home. The lesson to be learned is, do not 

 put your carnivorous and herbivorous shells in the same quarters, if 

 you want to keep both alive.
