large collection he had made the previous day in a locality near Chester, to which he hat been kindly introduced by Mr. Chantrell, the President of the Liverpool Microscopical Society, as a locality now abounding in a beautiful Rotifer Lacinularia socialis, and in a variety of fresh-water Polyzoa, of which Mr. Bolton also exhibited some specimens. The next day Mr. Bolton found on the same bit of weed the flower animalcule, (Floscularia cornula,) another Species of Ratifer, and afterwards Cephalosiphon limnins, and great numbers of the new collar-bearing flagellate monads, discovered and described by Mr. W. Saville Kent.—September 17th—Microscopical General Meeting. Mr. H. E. Forrest exhibited living specimens of Spirorbis nantiloides, a marine Annelid, showing compound ciliated tentacles, operenium, &c. Mrs. Robinson, a lady who has recently returned from India, exhibited and described a very interesting and extensive collection of specimens, consisting of ferns, butterflies, reptiles, &c.—24th September.—Geological Section}.—Mr. W. R. Hughes, on behalf of Mr. Councillor Pattison, showed interesting specimens of fossil wood and shells from Budleigh Salterton. Mr. W. Graham} exhibited some specimens of rocks collected during the excursion to Eastnor and Malvern. Mr. S. Allport mentioned that he had prepared a section of one of them, and it showed that the rock was a fine grained hornblendic rock greatly altered. Mr. W. Graham and Mr. C. Pumpbrey communicated an offer made by the Rev. W. G. Symonds of named specimens of the rocks of the Malvern district, for the purpose of microscopical and general examination. The Secretary was directed to accept the offer with thanks.—General Specimens exhibited by Mr. Levick and Mr. Forrest included (among others) from wear Barnt Green:—Lacinularia socialis, Deadrosoma radians, Chætospira Mülleri, Stephanoceros Eichkernii, and Polygarthra platypiera. By Mr. Slatter, Verbascum Blattaria, the fruit of the cherry laurel, Mr. Southall, Utricularia minor and U. intermedia, the latter being very rare. Mr, Wilkinson showed some monstrosities in radishes.—October 1st.—General Meeting, Mr. Bagnall exhibited same bladders of Utricularia minor, &c. Mr. W. Southall exhibited Phalaris arundinacea infected by ergot, (Clariceps pupurea.) Mr. S. Allport exhibited specimens of the Malvern rocks, consisting of contorted Mica-schist, hornblendic grieissoid rack, containing bitumen and sycuite from the North Hill. Mr. C. T. Parsons exhibited Lycium barbarum in fruit from Alton. Mr. T. Bolton exhibited Philodina roscola with Protacceus pluvialis, both in the motile and quiescent state, from Handsworth. Mr. H. E. Forrest exhibited living specimens of Zoothamnium, a lovely species of Vorticella, Stephanoceros Eichhornii, Lachinularia socialis, and other rare Rotifers all on one twig; also Sentor in the act of self division.—October 8th.—,Biological Section. A number of interesting objects were exhibited. These included mounted specimens of Carchesium polypinum, which had been killed by immersion in hot water, contributed by Mr. T. Bolton; branched colonies of Linnius ceratophylli, containing about twenty individuals, shown by Mr. H. E. Forrest; and a series of microscopic preparations of Utricularia, by Mr. J. B. Bagnall, showing the bladders in situ, and illustrating the structure of the valves and of the peculiar quadrifid processes. Mr. Bagnall accompanied the exhibition of his very interesting collection by notes on the geographical distribution of Utricularia, and by remarks on the structure and function of the bladders, recording the result of observations many of which were made previous to the publication of Mr. Darwin’s researches on the same subject. Mr. A. W. Wills exhibited the rare Rotifer Melicerta, or more properly Œcistes pilula, which he had shown under some disadvantage at a previous meeting, and referred to the classification of the thecated section of the Rotifers proposed by Mr. Cubitt, and to the structure of the genera Melicerta and Œcistes respectively, as justifying the inclusion of the species now referred to in the latter genus. Also a Rotifer belonging to the same genus, and secreting a large semi-transparent theca, also found in Sutton Park, and apparently identical with or closely resembling a species described by Mr. Oxiey at a recent meeting of the Royal Microscopical Society. As no name appears to have been proposed for this animal, Mr. Wills suggested that it should be called Œ. longipes, from the great length of its slender foot—October 15th—Microscopical General Meeting. Mr. Bolton exhibited Chætophora endiviafolia, one of the fresh-water alga, sent by Mr, Chantrell, president of the Liverpool Microscopical Society, Mr. Simcox exhibited a partition of Nautilus, ornamented by a native of New Caledonia; a large caterpillar, found with several others, three feet deep, in a creek near Sydney, N.S.W.; and a large operculum, and other parts
