300 General Notes. {March, 
title ofa little book by W. F. White, published by the London 
Religious Tract Society. The prolonged existence of Ichneu- 
mon in the pupa state is noticed by W. McRae in the Ent 
gist,p. 188. Several interesting papers on the Collembola, by6. 
Brook, have appeared during the past year in the Jou the 
Linnean Society of London; among others a revision of the 
genus Entomobrya, of which Degeeria of Nicolet is a synonym. 
Packard’s Degeeria 10-fasciata, a common U. S. species, is referred 
to the common European Entomobrya muttifasciata, of which 
Say’s Pedura fasciata is also regarded by Mr. Brook as ô 
synonym. 
ZOOLOGY 
OTES ON Mepusm — (Continued from February number) 
Stomatonema reticulatum, n. g. and s.—I have given the name 
Stomatonema reticulatum to a new Discophore from the South 
Atlantic, which has affinities with Cassiopea, Aurelia, and others 
and seems to me to throw considerable light on the homolog 
of certain peculiar bodies called “crests,” found on the pou | 
inder of that curious genus from the Florida Keys, knoe 
Stomolophus. i bell- 
he body isan inch and a half in diameter, 1$ rounded, , 
shaped above, with thick gelatinous walls. Th a 
bell is much thinner than the central region, and on were 
a fine reticulation of anastomosing tubes. The region os the bl 
work of tubes forms a narrow zone, whose outer edge 1s oe 
margin. There are no marginal tentacles as 1n Casstop 
some other related genera of Discophora. i i 
The marginal tin are more closely allied to a] 
Aurelia than to the same structures in Cyanea or jar inte l 
The sense-bodies are eight in number, placed at reg® z q wibi 
about the rim of the bell. Each sense-body 15 oo eyo! 
hood, and on either side, continued for a short ees gens 
the sense-bulbs, is a lappet similar to like structures 1M pt 
Aurelia. In addition to the zone of anastomosine Sis ss
