V. Report on the Recent Foraminifera from the 

 Coast of the Island of Delos (Grecian Archipelago). 



By Henry Sidebottom. 



Read October I sth. Received Nove}nber 2yih, igoj. 



The material was procured by Mr. Nevill, of Bramall 

 Hall, Cheshire, in the course of two cruises on board the 

 S. Y. "Victoria" (Captain Lunham), in the years 1894, 

 1895, and consisted of anchor mud and dredgings ; depth, 

 eight to fourteen fathoms. The usual process of washing, 

 floating, spinning and sifting into various sizes has been 

 carried out. In the case of the dredgings very little 

 washing was required, as they consisted chiefly of fine 

 sand, shell debris, and Foraminifera. The anchor mud 

 was composed of finer material, and lost more in weight 

 in the process of washing, but the yield of Foraminifera 

 in both cases was extraordinary. My brother-in-law, Mr. 

 Nevill, very kindly examined a large quantity of the 

 finest siftings, the examination of the rest of the material 

 being done by myself Mr. Nevill has also placed at my 

 disposal a fine collection of Foraminifera from the coast 

 at Palermo, and as they agree to a great extent with the 

 Delos forms I have placed an asterisk before the name of 

 the Delos species if it occurs at Palermo. I am greatly 

 indebted to my friend, Mr. F. W. Millett, of Brixton, 

 Devonshire, to whom my best thanks are due, both for 

 his help in the determination of many species and for 

 much information as regards the Foraminifera. My 

 thanks must also be rendered to my friend. Dr. Chaster, 

 of Southport, Mons. Chas. Schlumberger, of Paris, and 

 Prof A. Silvestri, of Spoleto, Italy, for their assistance 

 and for their courtesy at all times.
