discussion, in which Prof. Bower, Dr. D. H. Scott, Mr. Carruthers, and 

 Prof. Marshall Ward took part. 



"A new revision of the Dlpterocarpea" was the title of a paper by 

 Sir Dietrich Braudis, K.C.I.E., who gave an excellent account of this order 

 of forest trees, and their structure and mode of growth, together with a 

 survey of the literature relating to them, and a clear exposition of his views 

 concerning classification. He pointed out that the order Dipterocarpece 

 consists almost entirely of large trees which do not flower till they have 

 attained a great size, with a spreading crown on a branchless stem often 

 more than 100 feet high. Hence it is difficult to obtain complete specimens 

 in flower and fruit ; and this explains why a large proportion of the genera 

 and species have only of late years become accurately known. Notable 

 species are the Sal tree of India, Shorea robusta, great forests of which 

 extend along the foot of the Himalayas and in Central India; the Eng 

 tree, Dipterocarpus tuberculatus, of similar growth, in Burma; and others 

 found in Cochin China and Borneo. 



Dec. %0th.— Mr. C. B. Clarke, F.R.S., President, in the chair. 



Mr. Peter Ewing, of Glasgow, was elected a Fellow. 



Mr. W. B. Hemsley exhibited a series of specimens and figures 

 illustrating the parasitism of Loranthus aphyllus and other plants from the 

 Herbarium, Kew. 



Mr. J. E. Harting exhibited a specimen of a small Siberian Warbler, 

 Phylloscopus superciliosus, which had been obtained near Beverley, York- 

 shire, in October last, and made some remarks on its haunts, habits, and 

 migrations, and upon the previous instances which had been noted of its 

 accidental occurrence in the British Islands. 



Mr. H. M. Bernard gave the substance of a paper on the spinning 

 glands in Phrynus, not previously known, and described their position and 

 their morphological importance in Arachuidan phylogeny. The penis was 

 described as a pair oi rudimentary filamentous appendages of the genital seg- 

 ment, and consequently of importance as bearing further testimony to the view 

 that the limbs on the abdomen of the ancestral form were not plates as in 

 Limulus, but appendages like those on the thorax. The presence of these 

 limbs explains the curious genital operculum of the Pedipalpi, which is not 

 a primitive feature derived from Eurypterine ancestors, as some would 

 maintain, but a purely secondary specialization acquired within the Arachnid 

 phylum. 



A paper was then read by Mr. Percy Groom, entitled " Contributions 

 to the Knowledge of Monocotyledonous Saprophytes," or plants which are 

 dependent for their existence on the presence in the substratum of decaying 

 orgauic matter. He observed that, like parasites, they may be divided into 

 those which possess chlorophyll (hemisaprophytes) and those which have none
