SUMMARY OF CURRENT RESEARCHES RELATING TO 
lias also a considerable share in the constitution of the epimera. In the 
later stages of development the parts in question cannot be distinguished 
in the ventral wall of any segment. This share of part of the appendage 
(probably a homologue of the epipodite) in the formation of the ventral 
wall appears to be general in Isopods. 
Urothoe and Urothoides.* * * § — The Rev. T. R. R. Stebbing gives a 
monographic account of these genera of Amphipods, the second of which 
is new and is established for Urothoe lachneessa, described by the author 
in his £ Challenger’ Report. Of the former, eight species are recognized, 
which are more remarkable for their likeness to one another than for 
any differences that can be discerned. The size of the eyes and the 
structure of the lower antennae vary greatly with the age and sex of the 
animal : the most constant feature is the possession by the female of a 
two-jointed flagellum on the antennae. One characteristic of the genus 
is a vast number of gland-cells found all over the body, while others 
are the transparent caps to the tips of all the fingers, a peculiar spine- 
row on the wrist of the first gnathopods, and the long plumose setae on 
some of the appendages. 
New British Amphipods. f — The Rev. T. R. R. Stebbing and 
Mr. D. Robertson give descriptions of four new species of British 
Amphipods, which are called Sophrosyne Bobertsoni, Syrrhoe fimbriatus, 
Podoceropsis palmatus, and Podocerus cumbrensis ; they were all found in 
the Clyde. 
New and Rare French Crnstacea.j; — In the thirty-eighth of his 
communications on this subject M. Hesse describes a new Lepadid which 
he calls Cirrhipedes pedunculatus laciniatus , and in the thirty-ninth a 
Lernean found in the mouth of Cottus bubalis ; in the latter he offers some 
observations on the metamorphoses of Cirripeas during their embryonic 
period. 
Goniopelte gracilis— a new Copepod.§ — Prof. C. Claus describes a 
new member of the family Peltidiae — Goniopelte gracilis — characterized 
by the seven-jointed anterior antennas, the unjointed simple outer branch of 
the first pair of legs, and the marked reduction of the accessory branch 
of the posterior antennae. The similar form described by Brady as 
Goniopsyllus rostratus and referred to the Harpacticidae, is insufficiently 
characterized, and with it the species which Lazar Car described as 
Sapphir rostratus and referred to the Sapphirinae, is identical. 
New Pelagic Copepoda.|| — Dr. W. Giesbrecht continues his list of 
pelagic Copepods collected on the “ Yettor Pisani ” expedition, adding 
four new genera, Mornwnilla, JEgisthus , Consea, and Corina , and forty new 
species belonging to the above and other genera.
