26 Mr. A. Murray on Coleoptera from Old Calabar. 



Didymograpsus Moffatensis. 



This is the most elegant of the British species of this genus. 

 The base terminates in three distinct spinous processes. The 

 zoophyte bifurcates from the 

 base. The general appearance 

 is like the figure ; or occasion- 

 ally the lines form an acute 

 angle for about a quarter of 

 an inch, then suddenly ex- 

 pand in slight curves, almost 

 at right angles, for a short 

 distance, when they again recur 

 to their original direction. The 

 branches are united for about 

 a quarter of a line by a slight 

 web, which in some specimens 

 is terminated in a fine process 

 of short length, taking the 

 direction of a line bisecting the 



angle. The cells are arranged on the outer margins ; they are 

 very remote, and penetrate the polypidom to scarcely one-fourth 

 of its breadth ; they form slight openings on the margin of the 

 polypidom, first entering at a right angle, and then suddenly 

 turning downwards. These openings are lengthened ovate 

 pouches, answering exactly in shape and size to the cell-serra- 

 tures of the margin. The number of cells in an inch is about 

 twenty. The breadth of the polypidom is about two-thu'ds of 

 a line. 



This species is found in the shales at Hartfell. 



The specific name is derived from the locality where it is 

 found, which is in the neighbourhood of Moffat.
