viz., the respiratory apparatus at the end of the tail. Mr. Bousfield then 
gave the diagnoses of seven species, of which all are figured, four being new 
to Science. 
Mr. Stuart O. Ridley read a paper “On the Genus Lophopus, with 
Description of a New Species from Australia.” The latter was obtained by 
Dr. Von Lendenfeld near Sydney, N.S.W., and is distinguished from L. 
erystallinus chiefly by the great length of the tentacles, which equal that of 
the body of the polypide, and by the oval non-pointed outline of the 
statoblast. The new form, L. Lendenfeldi, is the fourth fresh-water Poly- 
zoon recorded from Australia, and the first species of its genus satisfactorily 
determined from the Southern Hemisphere. Staining with borax-carmine 
brings out certain multipolar nucleated cells in the ectocyst, which appear 
not to have been previously described in this genus. They perhaps indicate 
that the ectocyst contains mesodermal elements, and hence is something 
more than a mere epithelium. The characters of the species in question 
necessitate a modification of the old diagnosis of the genus as regards the 
shape of the statoblast.—J. Murtg.

the chair. 
The following gentlemen were elected Fellows, viz., Mr. Peter Cameron, 
of Sale, Cheshire; Mr. F. Archer, of Crosby, Liverpool; Mr. H. J. S. 
Pryer, of Yokohama, Japan; Mr. H. Norris, of St. Ives, Hunts; Mr. 
N. P. Fenwick, of Surbiton Hill; Mr. John Brown, of Cambridge; Mr. 
J. P. Tutt, of Blackheath ; and Mr. A. P. Green, of Colombo, Ceylon. 
Mr. K. B. Poulton exhibited a mass of minute crystals of formate of 
lead, caused by the action of the secretion of the larva of Dicranura 
vinula upon suboxide of lead. He stated that a single drop of the 
secretion had produced the crystals which were exhibited; and he called 
attention to the excessively high percentage of formic acid which must be 
present in the secretion, and to the pain, and probable danger, which would 
result from being struck in the eye by the fluid which the larva had the 
power of ejecting to a considerable distance. A discussion ensued, in 
which Messrs. White, Kirby, Slater and others took part. 
Mr. 8. Stevens exhibited a spécimen of Laphygma ewigua, recently 
captured by Mr. Rogers in the Isle of Wight. 
Mr. W. F’. Kirby exhibited, and read notes on,a specimen of Perilampus 
maurus, Walk., recently bred by Mr. Walter de Rothschild from Antherea 
tirrhea, Cram., one of the rarer South African Saturnide. 
Mr. T. W. Hall exhibited a number of specimens of Xanthia fulvago 
(cerago), somewhat remarkable in their variation, and showing a nicely
