1896, Amphilochoides intermedius, T. Scott, Fourteenth F. B. Rept., 

 pt. iii. p. 159, pi. iv. figs. 1-3. 



Bahitat. — Taken in various parts of the estuary, but 

 usually very sparingly. The latest records I possess of the 

 occurrence of A. intermedius in the Forth are for Station III., 

 where it was obtained on the 23rd and 25th of May 1901. 



Genus (29) Gitana, Boeck, 1870. 



46. Gitana Sarsi, Boeck. 



1870. Gitana Sarsi, Boeck, Crust. Amphip. borealia et arctica, p. 52. 



Habitat. — Taken very sparingly in various parts of the 



estuary. My most recent record of this species is for 



Station III., where it was dredged on 23rd and 25th May 

 1901. 



47. Gitana ahyssicola, G. 0. Sars. 



1892. Gitana ahyssicola, G. 0. Sars, Crustacea of Norway, vol. i. 

 p. 229, pi. Ixxviii. fig. 2. 



Habitat. — Dredged at Station VI. (off St Monans), 25th 

 May 1901. One of the characters which serves to distinguish 

 this small species from G. Sarsi is that the second pair of 

 coxal plates are rather narrow, and they exhibit only two 

 small serrations on the obtusely-pointed tips of these plates, 

 instead of three, as in G. Sarsi. 



Family Stenothoid^. 

 Genus (30) Stenothoe, Dana, 1852.

1862. Montagua marina, Bate, Catal. Amphip. Brit. Mus. , p. 56, 

 pi. viii. fig. 5. 



Habitat. — Various parts in the Firth of Forth from Inch- 

 keith to May Island, but not very common, 1889. Station 

 v., 24th April, and off the north-west end of Inchkeith, 

 23rd May 1901.
