Hahitat. — Loch Katrine and Loch Achray. This species, 

 which does not appear to be very rare, was described in 1895 

 from specimens found in some Shetland lochs. It has not 

 yet been recorded from England or Ireland.

1 The Alona intermedia recorded from Shetland in the Thirteenth F. B. 

 Report is not Sars' species of that name, but the Alona rectangula of G. 0. Sars, 

 I have no record for this species from the Forth basin, but as it is not rare, 

 especially in ponds and marshy places near the sea, it may yet be found in 

 the district.
