622 Reports and Proceedings — 



most nearly related to the Mantidse, the characters of the head and 

 thorax especially being to some extent paralleled in the existing genus 

 BlepJiaris. The author proposed to name the species Lithomantis 

 carbonarius, and suggested that Gryllacris (Corydalis) Brongniarti 

 probably belongs to the same genus. 



4. " On the Discovery of a Fossil Scorpion in the English Coal- 

 measures." By Henry Woodward, Esq., F.E.S., F.G.S. 



The author commenced by noticing the various European and 

 American localities in which fossil Arachnida have been found in 

 the Coal-measures. Hitherto no true Scorpions have been recorded 

 from the English Coal-measures ; but in 1874 the author received 

 from Dr. D. E. Eankin a specimen from the Coal-measures near 

 Carluke, which he regarded as the fossil abdominal segment of a 

 Scorpion ; in April last he obtained (through Mr. Hy. Johnson, C.E., 

 Dudley) a fossil Scorpion from the Sandwell Park Colliery ; and in 

 August Mr. E. Wilson forwarded to him two specimens of similar 

 nature in Clay-ironstone nodules from Skegby New Colliery, near 

 Mansfield. The specimens are all very imperfect ; but the author 

 states that they most closely resemble an Indian form which is 

 probably Scorpio afer. He refers the English species provisionally 

 to the genus Eoscorpius, Meek and Worthen, and proposes to name 

 it jEJ. anglicus. 



Discussion. — Mr. Charlesworth inquired whether the few Cretaceous fossils found 

 in the deposit which had furnished the New Zealand Crah descrihed might not he 

 the result of the degradation of pre-existing rocks. 



Dr. Hector replied that on stratigraphical grounds this could not be the case. 



Mr. Charlesworth stated that he had been unable to ascertain the precise locality 

 of the fossil Orthopterous insect described, but that he was informed by the gentle- 

 man from whom he received it that the nodule containing the specimen was picked 

 up by a lady near Airdrie, Scotland. 



Prof. Morris remarked that the New Zealand Crab was of especial interest. All 

 the previously described species of Harpaetocarcinus had been obtained from Num- 

 mulitic deposits in the south of Europe, and the same concurrence was observed in 

 New Zealand. Similar phenomena occurred in Australia, where many species resem- 

 bling European forms had been discovered by M'Coy. 



Mr. Etheridge said that one of Mr. "Woodward's papers demonstrated the value 

 of the Sub-"Wealden boring. He had examined the cores, and had come to the con- 

 clusion that the Oxford Clay was reached at 500 feet ; but in this he was mistaken, 

 owing to his having wrongly identified the Ammonite discovered at that depth with 

 Ammonites Jason. The occurrence of the same species of Crustacean at Boulogne 

 and in Sussex was of great interest, as marking the identity of the deposit in the 

 two localities. Lingula ovalis occurred with other fossils throughout the Eamme- 

 ridge Clay of the boring. 



Mr. "Woodward thanked Mr. Charlesworth for his endeavours to ascertain the 

 locality from which his Lithomantis was obtained. There could, however, be no 

 doubt as to its geological horizon. 



5. " The Drift of Devon and Cornwall, its Origin, Correlation with 

 that of the South-east of England, and Place in the Glacial Series." 

 By Thomas Belt, Esq., F.G-.S. 



The author described the general characters of the drift in the 

 district under consideration, and stated that on the uplands the drift 

 consists of undisturbed gravels and travelled boulders, which occur 

 only in isolated remnants on the lower ranges, and that in the low- 

 lands and valleys within 100 feet of the present level of the sea the
