VOLUME II, Part 11— MARINE HYDRACHNIDAE and 
HALACARIDAE. 
By Prof. H. Lohmaxn (Kiel). 
Pp. 151-154, with 2 figures in the text. 
Marine mites were found only at six stations, and only one 
specimen at each station. Indeed, these animals seem to be 
very scarce in these coastal districts, for, from a careful search 
of thirteen residues which appeared especially promising, no 
more than three specimens resulted. 
Of the four species, three belong to the Halacarids and one 
to the Hydrachnids. Two species were new. The other two 
species, Halacarus panopae and Agaue hirsula, show a wide 
distribution on the coasts of the warm water areas of the ocean, 
and have already been recorded from the south-eastern coast of 
Australia.

position of certain genera.

to families and subfamilies already treated in the First Pait of 
the Araneae (Vol. I, part 12), and then cotinues the enumeration 
and description of the species, going on with the family C lubiomdae , 
some subfamilies of which were treated in the final portion 
of the first part.
