in identifying, the different objects observed in the stomachs of fishes ; and 
therefore more satisfactory and reliable information respecting the food of 
fishes is now being collected. 
In preparing this paper the following among other works have been 
consulted : —

1868. Williamson, Recent Foraminifera of Great Britain.

Magazine of Natural History. 
1884. „ Foraminifera of the Challenger Expedition.

1870. „ and David Robertson, The Ostracoda of Tidal

I have also to acknowledge the kindness of Professor G. S. Brady, 
F.R.S., Dr H. B. Brady, F.R.S., the Rev. A. M. Norman, D.C.L., F.L.S., 
Rev. T. R. R. Stebbing, F.L.S., and Mr David Robertson, F.L.S., F.G.S., 
in naming obscure and difficult species. Indeed, but for the help of these 
gentlemen, this paper could not possibly have been so full or so valuable. 
FORAMINIFERA. 
I am indebted to Mr Robertson for indentifying a few of the species 
in this group mentioned below ; and also for notes of the occurrence of 
others which have not as yet come under my own observation. 
Miliolid^:. 
Miliolina tricarinata (d'Orbigny). 
Triloculina tricarinata, d'Orb., Ann. Sci. Nat., tome vii. p. 277, 
No. 7 a; Modele, No. 94 (1826). 
Miliolina tricarinata, H. B. Brady, Foram. Chall. Exped., p. 165, 
pi. iii. fig. 17, a-b (1884). 
Habitat. — ■ Vicinity of Bass Rock. This species is easily distinguished 
from M. trigonula by the three sharp keel-like ridges extending from end 
to end and about equidistant from each other. It is much rarer in the 
Forth then M. trigonula. 
Miliolina fusca, Brady. 
Miliolina fusca, Brady, Ann. and Mag. Nat. Hist., ser. iv., vol. vi. 
p. 286, pi. xi. fig. 2, a-c (1870). 
Miliolina fusca, Robertson, Fauna and Flora of the W. of Scotland, 
p. 51 (1876). 
Habitat. — Brackish water pools by the shore near Aberlady, common. 
This is an arenaceous species. It is much smaller than M. agglutinans, 
and frequently dark brownish in colour. It is considered to be a some- 
what rare species, and seems confined to water more or less brackish.
