Vol. 6S.'] THE MIDLAND AND SOUTH-EASTERN COAL MEASURES. 317 



I was strongly inclined to refer the species to the genus Athy- 

 modictya — a conclusion, however, with which Dr. Handlirsch does 

 not agree, as he is of opinion that the wing does not possess the 

 reticular intermediate venation of that genus. What the inter- 

 mediate venation is like I am unable to determine. If it consists, 

 as Dr. Handlirsch surmises, of single transverse veins, its affinities 

 may well lie near the Homoiopteridae, or, as I believe, still nearer 

 the Lithomantidae. It does not fall within either of these families, 

 however, nor can Dr. Handlirsch place it in any family with which 

 he is acquainted. It is inevitable, therefore, that a new family 

 should be formed in which to place it; and to this new family 

 I would give the name of Cryptoveuidse. 



Family Crypt ovenidae. 



Characters. — Wing twice as long as broad; inner and outer 

 margins gently convex ; apex rounded. Subcostal weaker than 

 costal, and merging in the latter before reaching the apex of the 

 wing. Eadius giving oi¥ a radial sector below the middle of the 

 wing, the tAvo enclosing a wide area, liadial sector and median 

 comparatively simple and with few divisions, the former ending on 

 the wing-margin in five rami, the latter in four. Cubitus with five 

 marginal rami. Anal veins strongly arcuate. 



Genotype : Cnjptovenia. Characters as above. 



I propose the specific name of moyseyi in honour of Dr. L. 

 Moysey, to whom I am indebted for the opportunity of describing 

 these insect-wings from the Middle Coal Measures. 



Horizon and locality. — Some 30 to 40 feet below the Top 

 Hard Coal, Middle Coal Measures, Shipley Clay-pit, Ilkeston 

 (Derbyshire). 



Lying at a lower level in the nodule, and partly obscured by 

 the wing of Cryptovenia moyseyi, was what appeared to be a 

 second wing. The position occupied by this structure will be 

 «een by reference to fig. 5 (PI. XXXII). The obscuring layer 

 was an extremely thin film of ironstone, which, as it bore the 

 impress of Gr. moyseyi, could not well be chipped away. By the 

 kindness of Dr. A. Smith Woodward, P.E.S., the specimen was en- 

 trusted to Mr. E. Hall, of the Geological Department of the British 

 Museum (Natural History), who succeeded with remarkable skill in 

 lifting, undamaged, the upper ironstone film and wholly exposing 

 the structure beneath. 



To Mr. Hall I am indebted for means of examining what 

 appeared to be a wing when partly exposed, but which, when fully 

 seen, resolved itself into a pinnule of JSfeuropteris. My inability to 

 regard it as a wing caused me to submit the question to Dr. Hand- 

 lirsch, who suggested that it might belong to Dictyojpteris or 

 J^eurojptetis. Dr. E. A. Newell Arber, who has seen the specimen 

 unhesitatingly refers it to the latter genus.
