436 Prof. J. Buckman on Libellula Brodiei. cesses from the succeeding lumbar and caudal vertebrae are plainly continuations of the parapophysial series. This repetition of a piscine structure^ although an exceptional one in the fish-like mammalia, has appeared to me to be so in-teresting a fact, as to be worth recording. I am not aware, at least, that it has been previously noticed. XLIII. — Remarks on Libellula Brodiei (Buckman), a Fossil Insect from the Upper Lias of Dumbleton, Gloucestershire. By Professor Buckman, F.G.S., F.L.S. As our associate, the Rev. P. B. Brodie, is leaving this district, I have much pleasure in calling the attention of the Members of the Cotteswold Club to the interesting discoveries of fossil insects from the Lias, which he has principally made within the limits of our more immediate operations, namely in the county of Gloucester ; and this I think right to do now with the more immediate object of settling a question of nomenclatiu'e, and in order that our 'Proceedings ' may perpetuate his name as attached to one of the most beautiful and perfect specimens he has yet dis-covered, to whom the following remarks will show that it was originally dedicated. In order to render this the more clear, it will be necessary to state that while Mr. Brodie was prosecu-ting his inquiries in the Lower Lias, in a band of which, termed by him the ' Insect Limestone,' he succeeded in exhuming re-mains of almost every class of Insecta, I had the pleasui'e of finding among others a fine wing of Libellula in a thin band of limestone in the Upper Lias : this discovery was announced to the Geological Society in a short paper " On the occurrence of Remains of Insects in the Upper Lias of the county of Glou-cester ;" and in vol. iv. part 1. page 311 of the ' Proceedings ' of the Geological Society will be found the following remarks: — " The remains of insects comprise one species of Libellula, which, from the reticulations of the fine wing, seems to belong to the genus jEshna, and has been named by Mr. Buckman jEshna Brodiei in honour of Mr. Brodie." Between this (June 21, 1848) and the publication of the 2nd edition of the ' Outlines of the Geology of the neighbour-hood of Cheltenham,' in 1845, 1 had the pleasure of discovering another fine wing, and this and the previous one were first figured in that work, tab. 8. figs. 1 & 2, with the following de-scription : — " Fig. 1. Posterior wing of jEshna Brodiei. " Fig, 2. Anterior wing of ditto." showing that I had arrived at the conclusion, that these two wings should both be referred to the same species.
