D)\ H. Woodward — British Carhoniferous Cod; roaches. 55 



I have much pleasure in dedicating this species to the memory of 

 its discoverer, the late Mr. Henry Johnson, F.G.S., Mining Engineer 

 of Dudley, than whom I have never known a more earnest and 

 enthusiastic worker, a more assiduous collector, or one who more 

 willingly lent his specimens for scientific purposes to those who 

 requested their loan. 



The specimen was obtained from an ironstone nodule from Coseley 

 near Dudley, and is now preserved as a part of the " Johnson 

 Collection" in the British Museum (Natural History).

This specimen consists of a single detached left wing presei'ved on 

 the surface of a piece of thin purple shale from "Bed No. 33 " in 

 the Upper Coal-measures near Meithil, on the coast of Fifeshire. 

 This shale-bed, which overlies the lower coal and thin limestone, con- 

 tains, with rootlets, rare specimens of species of Neurojiteris, Peco- 

 pteris, and Cydopteris, along with an Antliracomya? 



Although the border of the wing is somewhat imperfect, sufficient 

 is preserved to show its general form, and the venation of the wing 

 stands out in distinct relief on its surface. 



Outline of wing pointed-ovate, slightly flattened on its superior 

 border ; length of wing 15 mm., breadth 8 mm. The ' mediastinal ' 

 vein occupies rather more than a fourth of the entire area of the 

 wing ; it extends to about two-thirds of the length, where it unites 

 with the superior margin of the v/ing ; it branches six times, one of 

 these branches has three forks. The ' scapular ' vein extends nearly 

 to the extremity of the wing; it remains single for over one-fourth of 

 its length, and then branches into three veins, the middle one of
