small Crustacea, on the shore near low-water mark, to the east of Inver- 

 gordon, in the Cromarty Firth ; this he afterwards sent to me for exa- 

 mination. Several rare Copepods have been obtained in this gathering, 

 and one of them — Ectinosoma gracile — has already been referred to ; 

 another of these rare forms is the species under consideration. Only 

 four specimens of Huntemannia were obtained in this gathering 

 from Cromarty Firth, so that the species, which is very well marked, is 

 probably rare. The first pair of thoracic feet are stout, the outer branches 

 are three, and the inner one-jointed. They are armed with strong 

 marginal spines. The basal joint of the first feet carry each, interiorly, 

 a comparatively large thumb-like process, instead of a spine. This process 

 was quite conspicuous, even without dissection, in each of the four speci- 

 mens obtained. Probably the species is local as well as rare.

This somewhat remarkable species was described in 1898 from one or 

 two specimens obtained amongst some small Crustacea sent to me from 

 Lower Loch Fyne by Mr. F. G. Pearcey. They had been dredged from 105 

 fathoms. I have now to record the species from other two localities in 

 the Clyde district, and from moderately deep water — viz., from Station 

 XII., 40-43 fathoms, washed from mud brought up in the tow-net, 29th 

 August 1898 ; and from Station XVIL, Upper Loch Fyne, washed from 

 trawl refuse, 7th December 1898. Only one specimen was obtained in 

 each of these two gatherings.

This well-marked and somewhat rare species was described from 

 specimens obtained in the Firth of Forth. I have now to record its 

 occurrence in the Cromarty Firth, having obtained it in a gathering of 

 material dredged in the vicinity of Invergordon in 1896, but only recently 

 examined. 



Laophonte thoracica, Boeck. 



1863, Laophonte thoracica, Boeck, Overs. Norg. Copep., p. 54. 



What appears to be two forms of this species have been observed in 

 the Moray Firth district, one a deep-water form, which appears to be 

 the typical one. This was obtained in a gathering from Station XV. 

 (vicinity of Smith Bank), depth 24-49 fathoms, collected 20th November 

 1897. The other was obtained in the Cromarty Firth, and a little to 

 the west of Invergordon, where the depth of water is only a few fathoms, 

 and where there is usually a certain admixture of fresh water. 



Laophwiie serraia (Claus).

Laophonte serrata, which appears to be a rare species, occurred in the 

 same gathering in which the Huntemannia was obtained, and is now for 

 the first time recorded for the Cromarty Firth district-
