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. 



DECAPOD! 



CRANGONIDiE. 



Crangon fasciatus, Basso.* 



1816. Crangon fasciatus, Risso, 'Crust, de Nice/ p. 82, t. iii. 



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. 



Niha edidis, Risso. 



1816. Nikaedulis, Risso, 'Crust, de Nice,' p. 85, pi. lxxxiii. fig. 3. 



1853. Nika edulis, Bell, ' Brit. Stalk-Eyed Crust.,' p. 275. 

 Habitat. — 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. 



Bullion. 

 Cylichna nitidula, Loven. 



1846. Cylichna nitidula, Loven, ' Ind. Moll. Scand.,' p. 10. 

 1853. Cylichna nitidula, F. and H., ■ Brit. Moll.,' vol. iii. p. 



515, pi. cxiv. fig. 6. 

 1867. Cylichna nitidula, Jeffreys, 'B Conch.,' vol. iv. p. 412; 

 vol. v. pi. xciii. 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.
