to show that although a good deal has already 
been done towards working out the marine fauna 
of these islands, yet a judicious use of the dredge

taking investigator. The species observed by me 
that do not seem to have been previously recorded 
for these islands are as follows: 
Pontocypris acupunctata, Brady. 
Pontocypris acupunctata, Brady, Mon. Rec. Brit. Ostrac., p. 386, 
pl. xxiv., figs. 53-56 (1868). 
Brady and Norman, op. cit., p. 109, 
Habitat.—Near the mouth of Holm Sound; rare. 
The only other Scottish localities recorded for this 
species are the Minch; St. Magnus Bay, Shetland; and 
Firth of Forth. : 
Cythere robertsoni. Brady. 
Cythere robertsoni, Brady, Ann. and Mag. Nat. Hist., Ser. iv., 
vol. ii., p. 33, pl. iv., figs. 5, 8-10 (1868). _ 
Brady and Norman, op. cit., p. 139, pl. xiv., 
figs. 32, 33. 
Habitat.—Near the mouth of Holm Sound, south of — 
Deerness, in 12 fathoms; not common. 
This is a distinct though small species. With 
regard to its distribution, Drs. Brady and Norman 
say: “We have no record of this pretty and well- 
marked species from any part of the Scottish coast 
north of Loch Fyne.” *
