stitute of Mining Engineers ; and an article by Dr. J. Leitch, de- 

 scriptive of "The Geological Formation and Fossils of the new 

 Silloth Dock," recording the beds excavated and the occurrence in 

 different parts of remains of Cervus elaphus, Bos primigenius, and a 

 species of Balcevwptera. Some of the bones of Bos primigenius are 

 figured on a plate accompanying this paper. 



The papers on subjects of recent Natural History are only four in 

 number. Mr. J. C. Smith furnishes " Contributions towards a List 

 of Plants found in the Penrith Neighbourhood," consisting of a 

 list of about 130 species of plants with localities ; and Mr. W. 

 Duckworth, the first part of a paper on " Wild Flowers around 

 Carlisle," a pleasant gossiping article on common plants, with many 

 notes upon popular names, and other local particulars worth perusing. 

 Under *the head of Zoology we have also two articles: one on 

 " Shrikes," by the Ptev.ll. A. Macpherson, giving a popular account 

 of the species of Lanius found in Britain, and illustrated with a 

 lithographed figure of Pallas' s Shrike ; the other, the fourth part of 

 Mr. George Dawson's Notes on " Local Entomology," which deals 

 with the moths of the group Cuspidatte, and embodies some useful 

 notes on the collecting and breeding of those insects. The " Local 

 Scientific Notes and Memoranda " are also of interest, especially 

 those by Mr. T. V. Holmes and Miss Donald's Additions to the local 

 List of land and freshwater Mollusca.

The following communications were read : — 



1. "On the Relationship of Uiodendron, Lindley and Hutton, to 

 Lepidodendron, Sternberg, Bothrodendron, Lindley and Hutton, 

 Sig ill aria, Brongniart, and Ithgtidodendron, Boulay." By Robert 

 Kidston, Esq., F.G.S. 



The Author commenced by expressing an opinion that the so- 

 called genus Vlodendron of Lindley and Hutton comprised specimens 

 belonging to several species and even to different genera. Unless 

 the outer surface of the bark is well preserved, stems of Clathrarian 

 Sigillarice and Lepidodendra are undistinguishable ; but species of 

 Ulodendron have been in several cases founded on decorticated 

 examples, and distinguished b3 r such characters as the size of the 

 Ulodendroid scar. The three species which have furnished most of 

 the specimens described as Ulodendron, and to ^the description of 

 which the present paper is chiefly devoted, are Lepidodendron Vel-
