 front femora are almost like those of the male Pach i/lomera 

 femoralis, havinjj^ a tooth near tiie base connected by a 

 serrated carina with one of the two sharp teeth situated near 

 the articulation with the tibii, and the coxa is also toothed 

 in front. The <rreat broad front tibia is armed with four 

 teeth along tho anterior half of the outer edge, the inner edge 

 is serrated and above it is an upturned fringe of short hairs, 

 while the niiper face has also two small brushes of similar 

 hairs upm its anterior half. The middle and hind tibiie each 

 bear a blunt spatulate terminal spur, extending beyond the 

 tarsus in the middle legs, but ojily half its length in tlie hind 

 ones. The hind tibia has two parallel fringes of stitt" hairs 

 directed upwards, the inner one continuous and the outer 

 interrupted. Both pairs of tarsi are rather broad and the 

 ciaws are minute, short, straight, and n)t divergent.

December 4tli, li)lS.— Mr. G. W. Laraplugh, F.R.S., 

 President, ia the Chair. 



The following communication was read : — 



' The Carboniferous Succession of the Clitlieroe Province.' IJv 

 Lt.-Col. Wheelton Hind, M.I)., B.S., F.R.C.S., F.G.S., and 

 Albert Wilmore, D.Sc., F.G.S. 



The tectonic structure of the province consists of three dissected 

 jKiniUel anticlinal folds in beds of Carboniferotis- Limestone, Pendle- 

 side, and Millstone-CJrit age. The general direction of the axes of 

 these folds is east-north-east and west-south-west. Dissection has 

 exjKtsed the lower Ix^ds of Z, C, and S age, as the tect<»nic axes and 

 beds of D, P, and Millstone-Grit age occur on the flanks. 



The Limestone sequence shows all the zones from Z to D. 

 Modiola and Clcistopora phases have not l)een ex])o.sed, the base 

 <»f the Carboniferous not being seen. The Z beds are much thick- 

 ened, and not so fossiliferous as in the Bristol Province. C and S 

 beds are, as a rule, well-}).'d(U>d, with shales intercalated between 

 beds of limestone. There are crinoidal beds of considerable thick- 

 ness in places, and shell-breccias are common in S. Zophrentis 

 onui/ii/si indicates an im[)ortant horizon in Lower C, and these
