system; they likewise manifest a distinct Palaearctic facies, 
although one species (Criodrilus lacwwm) apparently ranges far 
into the Oriental Region. 
Polyzoa. 
Only two kinds of Polyzoa are! reported from the lake: 
Fredericella sultana jordanica and Plumatella auricomis. Both 
belong to cosmopolitan genera and both were only known 
g , 
The Polyzoa of the lake would, therefore, appear to pos- 
sess eastern or central Palaearctic affinities. 
Arachnida. 
The only aquatic Arachnida as yet found in the Lake of 
Tiberias are water-mites (Hydrachnida). My own small collec- 
tion of this group is still in the hands of Mr. J. N. Halbert, 
who has as yet been unable to find time to prepare a report 
upon them. 
Koenike* has recorded two species from the Lake of Tiberias, 
namely Atax crassipes, O. F. Miillar and H ygrobates longipal- 
pis, Hermann. Both these species are apparently of wide dis- 
tribution, but I am unacquainted with the literature of the 
group and am unable to give precise details.
