bcinj? a now species termed by the Author Dkustopora hrcmlolrnsis, 

 which has tubules simihir to those of D. ohelia. Those are the only 

 species in which tubules are known, and two modes of growth of the 

 fossil seem to show that those who united under Diustopora erect 

 and incriisting forms were right. 



The ovicell bj' the side of the zoarium oi Hornera serrata, described 

 in the paper, is in a position new for the Cyclostomata.

The following communications were read ; — 



1. " On the Occurrence of the so-called Viverra IlastingsicB of 

 Hordwell in the French Phosphorites." By li. Lydekker, Esq., 

 E.A., F.G.S. 



The Author shows that Viverra Hastingsice, Davies, is common 

 to the Oligocene of France and Hordwell, and finding that there is 

 no character by which the lower jaw of the type of the latter can 

 be satisfactorily distinguished from the type of V. amjustidens, 

 Filhol, he considers that V. Hastingsue is specifically inseparable 

 from V. angustideiis, and figures the cranium which is the subject 

 of the communication under the latter and earlier name. 



He gives a list of seven mammals known to be common to the 

 Headon beds of Hordwell and the Isle of Wight, and the French 

 Phosphorites.

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



In this paper the third right metapodial (metacarpal ?) and an 

 associated phalangeal of a Sauropodous Dinosaur, obtained by Mr. C. 

 Dawson from the bone-bed of the Wadhurst Clay, are described, and 

 referred with doubt to Mososaurus. 



The Author also discusses the relationship of Acantliopholis 

 platyims from the Cambridge Greensand.

The skull described in this paper is believed by Mr. T. Bain to 

 have been collected by himself near Beaufort West. The pre- 

 servation of the specimen leaves something to be desired, but not-
