On the Amphipoda of the Adriatic. By Camit HELLER. 
Whilst the Amphipoda of the northern seas, especially those of the 
Scandinavian and English coasts, have been treated of in works of de- 
tail, this cannot be said of those of the Southern European seas. 
The only work which treats the Amphipoda of the Mediterranean 
with some completeness is that of A. Costa. But scarcely anything 
has been hitherto known of the Amphipoda of the Adriatic. Pro- 
fessor Grube was the first to make us acquainted with some forms 
occurring at Quarnero. Professor Heller has now directed his par- 
ticular attention to this group of animals, and obtained an abundance 
of materials during his repeated visits to the Adriatic; and these have 
subsequently been increased by specimens sent him from various places. 
In this way he has been enabled to obtain a tolerably complete view 
of the Amphipodan fauna of the east coast of the Adriatic. In all, 
100 species have been observed by Grube and himself—namely, 
89 true Amphipoda, and 11 Lemodipoda; whilst, according to 
Costa, only 62 species are known from the Mediterranean, and, 
according to Bruzelius, only 77 frem the northern seas. This 
number, however, forms an unfavourable contrast to the British 
Amphipod-fauna, of which Spence Bate cites more than 200 species. 
The species observed by the author and characterized in his memoir 
are as follows :—
