glass, so as to press out the green globules which it contains, in order to bring the 
fusiform bodies into view. To these bodies I propose to give the name of tricho- 
cvsts. As long as the animalcule continues free from annoyance, the trichocysts 
undergo no change; but when subjected to external irritation, as occurs during the 
drying away of the surrounding water, they become suddenly transformed into long 
filaments, which are projected from all parts of the surface of the animalcule, and 
it is these filaments which, being mistaken for cilia by Cohn and Stein, gave rise to 
the erroneous views just mentioned.” (J. Glaisher) Snow Crystals, in 1855 ; (J.

No. 150, April:—(Rev. W. H. Hawker, A.M.) On Local Lists. This paper 
has appended to it a list of the Lepidoptera— e.g ., the Rhopalocera and theHetero- 
cera, as far as the end of the Sphinges—which were taken in the neighbourhood of 
Horndean, Hants. (W. A. Bromfield) Note on the Economy of Saturnia Pyri; 
(J. Scott) Are the Psychidae to be considered Bombyces or Tineina ? This small 
group of moths is, doubtless, in a miserable state at not being legitimately disposed 
of by entomologists, and should be everlastingly obliged to Mr. Scott for taking so 
much trouble to find it a quiet resting-place among the Tineina. (H. Evans)

“ curious” piece of nonsense. A little shot, from the fowling-piece of some bad 
marksman, drilled a few small holes in the leg of a teal, through which it drew 
some feathers, in the place of the very best silk, and covered all with some patent 
adhesive plaster, made of its own clotted blood! Electric Property in the

Trout (Salmo estuarius) ; (E. Newman) Memorandum of the Tadpole Fish. Mr. 
Newman says that the first dorsal of this fish is a slender, flexible spine, unaccom¬ 
panied by any membrane, which is a ^%ry different account from what Dr. Parnell 
gives in his account of the fish, and which account has been universally followed. 
We could have wished Mr. Newman had mentioned if there had been any trace of
