June 23, 1886.— Prof. J. W. Judd, F.R.S., 

 President, in the Chair, 



The following communications were read : — 



1. " On the Decapod Crustaceans of the Oxford Clay." By 

 James Carter, Esq., F.G.S., &c. 



The Author commented on the paucity of these fossils as indicated 

 in British lists, only three or four species having hitherto been re- 

 corded. 



The discovery of considerable numbers of Decapod Crustaceans in 

 the Oxford Clay of St. Ives has enabled the Author to increase the 

 list materially. Many have been collected by Mr. George, of 

 Northampton. These fossils occur in the clay immediately beneath 

 the St. Ives rock, and therefore presumably in the uppermost zone 

 of the Oxford Clay. Many of the specimens are more or less muti- 

 lated, but some fifteen or sixteen distinct species have been made 

 out. None of these have been recorded as British except Enjma 

 Baheaul, mentioned by Mr. Etheridge as having been found in the 

 Kimmeridge Clay. Seven species are identified as foreign forms, 

 and seven are new to science. They are distributed as follows : — 



Eryon 1 species. 



Eryma 5 or 6 ,, 



Glyphea 2 „ 



Magila 2 or 3 „ 



Mecochirus 2 „ 



Goniochirus 1 ,, 



Undetermined 3 ,, 



Nearly all the forms belong to the type of the Macrura, the Bra- 

 chyura being doubtfully, if at all, represented. 



2. " On a new Emydine Chelonian from the Pliocene of India." 

 By E. Lydekker, Esq., B.A., F.G.S. 



The Author described the shell of an Emydine Tortoise from the 

 Siwaliks of Perim Island, Gulf of Cambay, wbicli he regarded as 

 decidedly distinct from any of the previously-described Siwalik 

 species, and proposed to refer to the genus Clemnv/s, with the name 

 of C. Watsimt, in compliment to the donor of the specimen. 



November 3, 1886,— Prof. J W, Judd, F.R.S., 

 President, in the Chair, 



The following communications were read: — 



1, " On the Skull and Dentition of a Triassic Saurian, Galesanrus 

 plankeps, Ow." By Sir Richard Owen, K,C.B., F.K.S., F.G.S,, &c. 



The Author referred to a fossil skull from the Triassic sandstone of 

 South Africa, which combined dental characters resembling those of 

 a carnivorous Mammal with the cranial structure of a Saurian. 

 The structure was described and figured in Owen's ' Catalogue of 

 the Fossil Reptilia of S. Africa,' under the generic title of Gale-
