 tures, the Actinocycli and Coscinodisci found in the 

 stomachs of crabs from the west coast of Scotland, 

 of muscles from Scarborough, and of Pectens from 

 Brighton, occur equally in the waters of the Baltic, 

 in the sediments of the Mediterranean, and in the 

 guanos of Ichaboe, and Peru. Biddulphia pul- 

 chella has been found on our own coasts, in the 

 Mediterranean, on the shores of Long Island U.S. 

 at the Phillippine Islands, and at Cuba. 



The Foraminifera bring us to analogous con- 

 clusions. Globigerina bulloides is found on both 

 the coasts of America, at the Canary Islands, 

 in the Mediterranean, and in the Indian Sea.* 

 Bulimia elegantissima ranges from Patagonia to 

 the coasts of Chili and Peru.f Four other species 

 are common to Cape Horn and the Malvinas.J
