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- 

 cysts. 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-

 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)

 M 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

 Newman says that the first dorsal of this fish is a slender, flexible spine, unaccom-

 gives in his account of the fish, and which account has been universally followed.
