expressed an opinion that S. Powriei is a full-grown male, and 

 S. Scoticus a young female of the same species ; but Mr. Woodward 

 observed that if the sexes are not to be determined by the thoracic 

 plates, but by more general characters, then the two forms of plates 

 in Slimonia indicate two species of females, and the two forms in 

 Pterygotus minor ought to indicate two species of males. 



5. " On a new genus of Eurypterida from the Lower Ludlow 

 Rocks of Leintwardine, Shropshire." By Henry Woodward, Esq., 

 F.G.S. 



In this paper Mr. Woodward described a Crustacean alluded to by 

 Mr. Salter in the ' Annals and Magazine of Natural History ' for 

 1857, under the MS. name of Limuloides. It appears to form a 

 connecting link between the Xiphosura and the Eurypterida, but it 

 differs from the former in not having a cephalothorax — the cephalic, 

 thoracic, and abdominal divisions being distinct, and apparently 

 capable of separate flexure ; and from the latter in having only three 

 thoracic segments, &c. The name Limuloides not being allowable 

 as a generic appellation, the author applied it to the species, using 

 the generic term Hemiaspis.

 I. " On the Carboniferous Rocks of the Valley of Kashmere." 

 By Capt. H. Godwin-Austen. With Notes on the Carboniferous 

 Brachiopoda, bjr T. Davidson, Esq., F.R.S., F.G.S. ; and an Intro- 

 duction and Resume, by R. A. C. Godwin-Austen, Esq., F.R.S.,

 F.G.S. 



This paper was a continuation of one read before the Society last 

 year, in which the Carboniferous, Jurassic, and Post-tertiary de- 

 posits and fossils were described by Capt. God win- Austen, Mr. 

 Davidson, and Mr. Etheridge. In this communication Capt. God- 

 win-Austen confined himself to the Carboniferous formation, which 

 was shown by him to have, in the Valley of Kashmere, a thickness 

 of more than 1500 feet. The upper portion of this mass contained 

 but few fossils, except in one particular bed near the entrance of the 

 ravine above the village of Khoonmoo ; but the lowest portion, or 

 Zewan bed, is made up chiefly of the remains of Brachiopoda and 

 Bryozoa; and a higher stage, though still near the base of the 

 formation, contains abundant remains of Producti. The position of 

 a limestone containing Goniatites is not very clearly determined, 

 but it is probably a member of the Zewan series. 



The sections in which the relative positions of the different beds 

 were exhibited were described in detail, and plans and a map were 

 given showing their geographical relation. 



Mr. Davidsou described the Brachiopoda forwarded with the 

 paper, stating that they abound particularly at Barus and Khoon- 

 moo, but are rarely in a very good state of preservation. Among 

 them are several common and wide-spread European and American
