Habitat.—Firth of Forth, in surface tow-net east of Inchkeith; not 
very common; December 1890. This species has also been recorded for 
St Andrews Bay by Professor M‘Intosh.

DULICHYID#. 
Dulichia porrecta (Spence Bate). 
1857. Dyopedos porrecta, Spence Bate, ‘ Ann. Nat. Hist.,’ 2nd ser., 
vol. xix. p. 151. 
1868. Dulichia porrecta, Bate and Westwood, ‘ Brit. Sess.-Eyed 
Crust.,’ vol. 1. p. 21. 
Habitat.—Off Musselburgh, Firth of Forth, among trawled material 
(weeds, zoophytes, &c.) ; a few specimens only; April 1891. The pro- 
podos of the second Gnathopoda are armed with the two prominent for- 
ward-directed teeth characteristic of the species.

1888. Leptaspidia brevepes, Robertson, ‘ Amphipoda and Isopoda 
of the Firth of Clyde,’ p. 76. 
Habitat.—Off 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, Loch Fyne ; but it does not appear to 
be a common species anywhere. There is no danger of mistaking it for 
Munna, though it seems to be nearly allied to that genus.
