282 PROCEEDINGS OF SOCIETIES. 



will appear in the next number of this Journal. Specimens of ap- 

 parently similar insects described by Mr. Tatem as Acarelliis Muscm, 

 to which allusion was made in Mr. Mclntire's paper, were sent to the 

 meeting for comparison by Mr. Tatem, and were exhibited under the 

 microscope by Mr. T. Curties. 



The thanks of the meeting were unanimously voted to Mr. 

 Mclntire for his paper. 



The President, after remarking that the paper seemed to open up 

 questions as to the relationship of supposed distinct species of Acarelli, 

 announced that the Society would hold a scientific evening on 

 December 10th. 



The meeting was then adjourned to December 3rd.

October 7, 1873. 



Captain Lang exhibited the so-called Gomphonema coquedense, 

 which appears to be merely the sporangial form of G. geminatum, 

 being sparsely scattered amongst a gathering of that species. He 

 also exhibited a ten-angled Triceratiiim favus, a recent Omphalopelta 

 versicolor, and an Adinoptychus trilingulata. All these had been 

 kindly sent by Mr. Kitton, who states that the last has never (he 

 thinks) been found except by himself and Mr. Brightwell in some 

 West Indian material. Captain Lang, however, showed valves from 

 Singapore shell-cleanings which Mr. Kitton, to whom they were 

 sent, thinks identical. In the opinion of Captain Lang, Omphalopelta 

 versicolor must certainly belong to the same genus as Actinoptychus 

 trilingulata; and now that the absence, presence, or number of the 

 processes is allowed to be immaterial, he would suggest that the 

 genus Omphalopelta should be abolished, as it has been by Professor 

 H. L. Smith in his new Conspectus of the Diatomaceae. 



Mr. Tatem exhibited gizzards of insects mounted as opaque 

 objects on white-spot groimd, viz. those of the cricket, cockroach, 

 Carahus nemoralis, Carahus violaceus, Hydrophilus, Goerius olens. 



Mr. Austin exhibited small fungi, Didymium cinereum, Diderma 

 vernicosum, Helminthosporium TilicB, Helminthosporium Smiihii, section 

 of Peziza leporina, and growing tip of root of Poa annua, stained with 

 carmine.
