725 species belonging to 185 genera as compared with 843 species 

 belonging to 90 genera in Vol. VII., and 720 species belonging to 

 101 genera in Vol. VIII." 



This volume commences with a revised table of genera of the 

 subfamily Acronyctince and a folding diagram of the phylogeny ; 

 and pages 496-535 are devoted to additions and corrections to 

 Vols. VII. and VIII., and to a list of undetermined species pre- 

 sumed to belong to the Acronyctince. 



The execution of the letterpress and illustrations is similar to 

 that of previous volumes, and calls for no special comment. A 

 considerable number of species here dealt with belong to well-known 

 European genera, such as Gortyna, Apamea, Hydrcecia, Pyrrhia, 

 TpimorpJia, Calymnia, Dicyda, Arenostola, Ccenobia, Sesamia, Cala- 

 mia, Euterpia, Panemeria, &c, and also several exotic genera, such 

 as Psydiomorpha, Ovios, and Seudyra, which have generally been 

 (at least provisionally) referred by previous authors to the families 

 Agaristidae, Lithosiidao, &c.

January 26th, 1910.— Prof. W. J. Sollas, LL.D., Sc.D., F.R.S., 

 President, in the Chair. 



The following communications were read : — 



1. ' On a Skull of Megalosaurus from the Great Oolite of 

 Minchinhampton.' By Arthur Smith Woodward, LL.D., F.R.S., 

 F.L.S., Sec. G.S. 



The specimen was discovered and prepared by Mr. F. Lewis 

 Bradley, F.G.S., and shows for the first time the skull of Megalo- 

 saurus. It agrees closely with the Megalosaurian skulls of other 

 genera already discovered in the Jurassic and Cretaceous of North 

 America, and resembles Ceratosaurus in possessing a bony horn- 

 core on the nose. As in the jaws of Megalosaurus previously 

 known, the premaxilla of the new specimen bears four teeth ; but 

 these teeth are so different from those of the typical M. bucklandi 

 of the same horizon, that they prove the Minchinhampton fossil to 

 belong to a distinct species. 



2. ' The Vertebrate Fauna found in the Cave-Earth at Dog Holes, 

 Warton Crag (Lancashire).' By John Wilfrid Jackson, F.G.S., 

 Assistant Keeper in the Manchester Museum. 



The remains described in this communication were obtained 

 during the systematic investigation by the Author of a cave on 

 Warton Crag (West Lancashire) in 19u9. 



The cave, known as Dog Holes, is situated on the western side 

 of Warton Crag, and opens on a sloping < pavement ' of limestone. 

 It owes its origin to the erosion of a series of master-joints in the 

 Carboniferous Limestone.
