advanced state of development and that most of the females 
had apparently hatched their brood. 
The larva of Atyaephyra was described by Joly in 1843 
(loc. cit.) and we have little to add to his observations, which 
are fully illustrated by good figures. Indeed, larvae from the 
neighbourhood of Tiberias agree with these in every respect, 
except that their tails are more distinctly bilobed and that 
their rostra are more delicate and less prominent. He gives an 
excellent description of the appendages, which closely resemble 
those of the larvae of Caridina wyckii (=nilotica) as described 
by Von Daday ! and of Xiphocaridina compressa as described by 
Ishikawa.? The Tanganyika Atyid larvae described by G. 0. 
Sars* and attributed by him with a query to the genera 
Limnocaridina and Atyella are apparently hatched at a some- 
what earlier stage. 
Atyaephyra desmaresti occurs all round the Mediterranean, 
in N. Africa as well as in Europe. It has been recorded from 
‘Portugal and appears to be widely distributed in France, but 
is not included by Keilhack + among the German freshwater 
Malacostraca. 
In the Lake of Tiberias it is scarce. Barrois®, however, 
obtained a few specimens from a depth of 5 to 8 metres at 
the south end, probably in the channel of the River Jordan 
in which there are submerged beds of Vallisneria. In the 
immediate vicinity of the lake it is, as Barrois states, ex- 
the banks, while in the others it was only noticed among water- 
weeds, especially, but not exclusively, Ranunculus aquatilis.
