AMPHIPODA. 
A. Bceck (/. c.) gives a full account of the northern Amphi- 
poda ; but, owing to the late receipt of the paper, an abstract of

The so-called Leydigian organs on the first pair of antennae, 
first observed by La Valette in Gammarus puteanus, and after- 
wards accurately described and stated to be sensitive organs by 
Leydig, are the subject of a paper by P. Jarschinski (/. c.), 
who has observed them in various genera of Amphipoda.
