A single specimen comes from Cultra; and one problematical example from 
Carland. This species is found in the Lower Carboniferous strata of Fifeshire, 
Linlithgowshire, Ayrshire, Roxburghshire, Northumberland, Westmoreland, and 
Yorkshire.

This fine large form, from Carland, is probably a Macrocypris, allied to the 
apparently variable species Macrocypris Jonesiana. It is higher (broader) relatively 
in the middle, more arched on the back, and higher and more broadly rounded 
on the anterior (blunt) extremity, than Kirkby’s typical figure. It is much more 
highly arched than Jones’s figure, and its end more unequal. It is higher than 
the latest of the figures, and has not the hinder end so sharp and tapering. 
This species is known from the Lower Carboniferous strata of both the South 
and the North of England, and from the West and the East of Scotland; also from 
the Permian of Durham and the Wetterau (now in the province of Hesse-Nassau).

(Plate xu., figs. 17, 18a, 4.) 
In looking for published analogues of these specimens from the Cultra Shales 
(having none in our own possession), we readily find some neat, elongate, sub- 
cylindrical forms in Dr. G. 8. Brady’s monographs, which attract our notice, such
