sions -of fresh- water amphibians * * * Megapez'm (?) color- 

 adensis [Lull, 1918], and Exocam/pe (?) delicatula [Lull, 1918]. 

 Some of the tracks are distinct impressions of the feet, and others 

 are mere strokes of the toes. In these same beds also occur plant re- 

 mains in very fragmentary condition which were badly macerated 

 and coated with a slime of red mud during their entombment. They 

 are therefore difficult to determine, but after much effort Dr. David 

 White tentatively identified them as CaUipteris sp., cf. C. conferta, 

 Walchia cf. W. gracilis^ Gigantopteris^ and cf. Sphenophyllum'''' 

 (Schuchert, 1918). The footprints are of little value in determining 

 the age of the deposit, but the plants led Doctor AVhite to consider 

 the Lower Permian as most probable. " The condition of preservation 

 of the fragments is so bad that caution is necessary in basing con- 

 clusions of any kind on the material submitted. However, the pres- 

 ence of Gigantopteris^ Walchia, and probably of GaTlipteris, if my 

 tentative generic classification of the latter is correct, points to the 

 Lower Permian age of the flora " (Schuchert, 1918). 



In 1916 Doctor Noble made a second collection of plant material 

 from the beds at the Hermit Trail. This collection was again ex- 

 amined by Doctor White, who determined the species as Pecopteris 

 (?) species, AlethopteHs (?) species, and CaUipteris (?) species, 

 which once more indicated that the beds were Permian age, or possi- 

 bly the very latest Pennsylvania. In 1920 Noble again collected at 

 the Hermit Basin, in addition to a few other plants, a well-preserved 

 specimen of a species of CaUipteris. In connection with this speci- 

 men Doctor White said : " * * * This evidence practically con- 

 firms conclusively the opinions based on fragments previously col- 

 lected * * * and is of itself probably adequate to prove the 

 Permian age of the Hermit Shale " (Noble, 1922). 



The rock containing the insect is clearly from the " fine grained 

 friable sandstone," ratlier than from the shale bed, and is a poor type 

 of rock for the proper preservation of an insect. The surface is 

 very rough and irregular, and the wing shows signs of maceration, 

 as in the case of the plants examined by Doctor White. The con- 

 dition of the specimen is rendered even worse by the lack of the 

 reverse, which appears to have broken away with the obverse half 

 of the center of the wing. Had the fossil represented a new group 

 of insects, it would have been impossible to determine its affinities 

 with any degree of satisfaction. Fortunately, the species is easily 

 recognized as belonging to the Order Protodonata, and may be placed 

 in a genus already established by Sellards. 



Family MEGANEUPvIDAE 



The subfamily Typinae, to which this new species unquestionably 

 belongs, consists of two genera from the Lower Permian of Kansas :
