SUMMARY OF CURRENT RESEARCHES RELATING TO 
are Mysinfe ; four genera, one of whicli is new, and eight species are 
recognized ; of these last four are not yet known beyond the Caspian, 
while four are stated to inhabit also the Black Sea. The new genus 
Katamysis ( K . Warpachoivskyi sp. n.) is chiefly distinguished by the 
very remarkable reduction of the terminal part of the four posterior 
pairs of pereiopods, which look as if they had been mutilated. 
In the second part * of his report on the Crustacea of the Caspian 
Sea, Prof. G. 0. Sars deals with the Cumacea. Contrary to expectation, 
the group is very well represented, and several of the forms are a good 
deal larger than their oceanic allies. Some have a most peculiar aspect, 
in consequence of the strange development of dorsal crests on the free 
segments of the mesosome. All the species belong to the genus Pseudo- 
cuma. 
Entomostraca from Gulf of Guinea.f — Mr. T. Scott has a report on 
the Entomostraca obtained by Mr. J. Rattray in the Gulf of Guinea by 
net-gathering. One hundred and forty-eight species of Copepoda, two 
of Cladocera, and twenty-four of Ostracoda are enumerated ; great 
variations were observed, and due note has been taken of them in 
establishing new genera and species. 
Ostracoda of Naples.^ — Herr G. W. Muller has published a hand- 
some report on the Ostracoda of Naples and the Mediterranean. The 
■whole work is of the elaborate kind to which Dr. Dohrn has accustomed 
us, and there is, as usual, a great wealth of illustration. On the whole, 
Sars’ division of the order into the Myodocopa and the Podocopa is
