320> 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 

 4 finest of the British Harpacticidae.' It has, somewhat like Alteutha 

 dejyressa, 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.
