_ §planchnostrophus. Some notes on the latter genus, and on an Acarus, 
parasitic on Galvina rupium are added. Mr. Mörch has given a detailed 
account of the Mollusca of the Faroe Islands (Cephalopods, three spe- 
_ cies; Brachiopods, one species; Gasteropods, sixty-five ; and Bivalves, 
3 forty-two species), illustrated by an instructive tabular synopsis of the 
geographical distribution of the Mollusks of Iceland and Faroe.

4 Moose Tick.—On the 13th of April a pair of young moose were 
l brought through New York on their way to Europe. They were raised in 
E Nova Scotia, and being very tame, were allowed to run at large. The 
cow moose would ramble off in the woods, and while there, had become 
infested with ticks; the bull had escaped contact with these insects. 
When the cow arrived in New York, her sides and back were almost 
covered with adult ticks. The insects were removed very much to the 
to do so until the 25th of June, when 
they died. The eggs are forced out 
inlarge masses. On the 3d of July, 
_ the day after I sent the drawings to 
_ you, the entire mass of eggs seemed 
to hatch out at once, the shell open- 
- ing like a clam, and releasing a six- 
legged insect.—W. J. Hays
