The species is apparently common on the shore of the Chilka Lake somewhere 

 near Satpara, where the beach is for the most part sandy. It is dug for bait by 

 fishermen. Specimens obtained from them in March, 1914 were not quite mature. 

 The corrected specific gravity of water from the lake at Satpara was in this month 

 1*026. In Palestine the worm lives in wet earth under stones at the edge of water. 



This is a well-known European species, which occurs throughout Central Europe, 

 in S. Russia, Syria and Palestine. It is interesting to find it in brackish water, since 

 it is a typically limnic form, and so far as I know has not hitherto been recognized 

 as littoral. That it can support a considerable amount of salt is, however, shown by 

 its occurrence on the margin of the Lake of Tiberias, the water of which is markedly 

 saline; and this being the case, it is perhaps remarkable that it has not so far defi- 

 nitely established itself as a littoral form.
