character of the following Silurian British spiral-bearing species of 

 Brachiopoda, and any one possessing duplicates available for that 

 purpose could not serve science better than by placing them in the 

 able hands of the Eev. Norman Glass: — Meristella f angustifrons, 

 M'Coy, sp. ; M. ? Circe, Barrande ? ; M. ? Maclareni, Haswell ; M. 

 ? crassa, Sow. ; M. f sub-undata, M'Coy ; Atrypa ? hemisphcerica. 

 Sow. sp. ; u£. ? Scotica, Dav. ; A. Headii, Billings. The so-termed 

 Triplesia ? monilifera, M'Coy ; Triplesia ? Orayics, Dav. ; Merista 

 ? camarium or cymhida, Dav. ; and the Bhyn. ? Pentlandica, also 

 require internal investigation. 



The Eev. Norman Glass has also recently been devoting much 

 attention to the loop and spiral -bearing species of British Devonian 

 Brachiopoda, with admirable results, which we hope to make known 

 in the sequel. 



III. — Two New British Cakboniferous Insects, with Eemarks 



ON THOSE ALREADY KNOWN. 



By Samuel H. Scudder, Esq. 



Assistant- Librarian, Harvard College Library, Cambridge, Mass., U.S.A. 



BY the kind communication of my friend, the Eev. P. B. Brodie, 

 M.A., F.G.S., I have been able to study two very striking 

 wing-fragments from the Coal-measures of Great Britain, which are 

 interesting, not only from the excessive rarity of such remains in 

 this country, but also from their relationship to the two or three 

 already known. 



"Wing of Brodia priscotincta, Scudder. Coal-measures, Dudley Coal-field, 

 Staftordsbire. 



The first, which I call Brodia, in honour of the distinguished 

 writer on the Insects of the Secondary rocks of England, is an 

 ancient form of Planipennia or true Neuroptera, the structure of 

 whose wings does not agree with that of any of the existing 

 families of the group, but rather shows a combination of features 

 which now distinguish separate families. It has the general aspect 

 of a gigantic Panorpa, borrowed from its form, its markings, the 

 presence of a few scattered, cross-veins, and the course of the 

 mediastinal nervure. When, however, its neuration is carefully 

 observed, the scapular vein is seen to be fundamentally different, 

 though its position and the origin of its main branch is similar ; for, 

 while in both cases the area it occupies is important, in the Panor- 

 pina the main branch divides dichotomously throughout, and its
