of the Fishery Bourd for Scotland. 309 
Habitat.—East of Inchkeith. Rare. Specimens have been obtained 
from other parts of the estuary, but seldom more than one or two at a time. 
It is easily distinguished from the other two British species by the slightly 
forked telson. I have also obtained Mysidopsis angusta in Loch Fyne 
and in the Moray Firth. There are now twenty well-authenticated 
species of Schizopoda included in the Forth fauna. 
DECAPODA. 
CRANGONIDA. 
Crangon fasciatus, Risso.* 
1816. Crangon fasciatus, Risso, ‘Crust. de Nice,’ p. 82, t. i11. 
fig. 5. 
1853. Crangon fasciatus, Bell, ‘ Brit. Stalk-Eyed Crust.,’ p. 259. 
Habitat.—Off Musselburgh, Firth of Forth. Two specimens of this 
pretty little species were captured with the bottom tow-net in 4 to 5 
fathoms water. ‘The contrast of colour was very marked in these speci- 
mens, the cephalo-thoracic and fourth abdominal segments being dark 
chocolate brown, and a band of the same colour across the tail append- 
ages, while the other parts were nearly white. The squarely-truncate 
rostrum is a well-marked characteristic of the species. 
Crangon neglectus, G. O. Sars.* 
1882. Crangon neglectus, G. O. Sars. 
Habitat.—Largo Bay; several specimens among weeds dredged in 
about 8 to 9 fathoms water. This is quite distinct from the previous 
species, and also from C. nanus. The rostrum is broadly rounded in this 
species. It does not appear to have been previously recorded for the 
East Coast of Scotland. 
Nika edulis, Risso. 
1816. Wika edulis, Risso, ‘Crust. de Nice,’ p. 85, pl. lxxxiii. fig. 3. 
1853. Nika edulis, Bell, ‘ Brit. Stalk-Eyed Crust.,’ p. 275. 
Halitat.—-Seven to eight miles east of May Island; rare. It has been 
obtained by Edward in the Moray Firth, where I also observed it. It is 
recorded from Loch Fyne, and from Brodick Bay, Firth of Clyde, by 
Professor J. R, Henderson,+ but nowhere does it appear to be very 
common. 
MOLLUSCA. 
BULLIDZ. 
Cylichna nitidula, Loven. 
1846. Cylichna nitidula, Loven, ‘ Ind. Moll. Scand.,’ p. 10. 
1853. Cylichna nitidula, F. and H., ‘ Brit. Moll.,’ vol. iii. p. 
515, pl. exiv. fig. 6. 
1867. Cylichna nitidula, Jeffreys, ‘B  Conch.,’ vol. iv. p. 412; 
vol. v. pl. xciil. fig. 2. 
Habitat.— West of May Island; rare. A few specimens were obtained 
from the stomachs of haddocks—a source from which a few other rarities 
have been obtained.
