very common; December 1890. This species has also been recorded for 
St Andrews Bay by Professor M'Intosh.

Habitat— on Musselburgh, Firth of Forth; rare; April 1891. This 
species, seen from above, is broadly ovate ; it is also considerably 
depressed. The species is a very small one, being little over the one- 
twentieth of an inch in length. It was first obtained by Mr Robertson 
at Cumbrae, and described in ' British Sessile-Eyed Crustacea.' I have 
observed it in East Loch Tarbert, lioch Fyne ; but it does not appear to 
be a common species anywhere. There is no danger of mistaking it for 
Miinna, though it seems to be nearly allied to that genus.
