Pari III. — Eighth Annual Report 
Habitat. — Off St Monance, frequent. Dr Brady says that this species 
' must be looked upon as one of the rarest, as it is certainly one of the 
* finest of the British Harpacticidse.' It has, somewhat like Alteutha 
depressa, a broad reddish purple band across the thorax. 
(Family uncertain.)

Habitat. — Off St Monance, frequent. This species, which does not seem 
to have been previously recorded for Scotland, might be easily passed over 
as belonging to some other group than the Copepoda. Its comparatively 
long and cylindrical form and short swimming feet impart to it a somewhat 
close resemblance to a young Pseudatanais — a kind of Isopod. Both the 
genus and species were described from a single specimen dredged off 
Hartlepool, and from the structure of the mouth it was conjectured to be 
of parasitic or semiparasitic habits. All the specimens found by me have, 
however, been unattached to any other organism. I also found this species 
in East Loch Tarbert (Loch Fyne) in 1885, but it was not recorded. It 
has been observed by the Kev. A. M. Norman at Plymouth. 
Fifteen species of Copepoda are recorded above, which brings up the 
number observed within the area of the Firth of Forth to sixty. I 
expect that this number will be yet further increased. There are several 
forms that are doubtful, or that have not yet been identified with 
described species, which will be recorded later on. I am greatly indebted 
to Dr G. S. Brady for the trouble he has taken in examining and identi- 
fying doubtful species, not only belonging to this, but also to the following 
group, the Ostracoda. 
OSTRACODA. 
Thirty-two species of Ostracoda are here added to those recorded in my 
two previous papers. Four of these have not as yet been identified with 
known species, and are for the present provisionally named and described. 
I am also indebted to Mr David Robertson for notes of a few species not 
as yet observed by me in the Firth of Forth.

Habitat. — Bo'ness (David Robertson). A note of the occurrence of this 
rare and interesting species was communicated to me by Mr Robertson, 
who observed it among some material he had collected at Bo'ness some 
years ago. The only localities where it had previously been recorded from 
are Westport Bay, Roundstone Bay, and Birterbuy Bay, Ireland.
