as distinct from the outspread flattened contour of C. foliacea. 
Probably the real zoological significance of the character is not 
great; but it seems quite worth recognizing.

An extreme enfeeblement of Q. seminulum, Spiroloculine in 
aspect, and twisted on itself. Several small specimens of this 
have been found by Mrs. SHone in the Dee, but it is more at 
home in the deeper waters of the Mediterranean and other Seas. 
It also occurs fossil in the Lias Clay of Stockton, Warwickshire. 
Trochammina Shoneana, nu. sp., fig. 1, 2. 
Cuaracters.—Test spiral, subcylindrical, slightly tapering, narrow end 
rounded ; composed of a single series of close conyolutions of a non- 
septate tube on a linear axis. Sutural line more or less depressed 
externally. Aperture large, rounded, formed of the end of the tube, 
somewhat constricted. Texture finely arenaceous; colour light 
brown to rusty red. Length ai oth to doth inch.

This form is closely allied to Trochammina gordialis, and T’r. 
charoides. It differs from the former in its elongate regular 
habit of growth, and from the latter in the extension of the 
convolutions lengthwise in single series, instead of their super- 
position in several layers.
