Eucalanus elongatus (Dana). 
1849. Calanus elongatus, Dana, Proc. Amer, Acad., vol. ii, p. 18. 
A single specimen—a female—was obtained in the same gathering with 
the last. This is a larger species than Hucalanus crassus; the specimen 
referred to here measured fully 6mm. in length (about a quarter of an 
inch), In this species the last thoracic segment has the sides produeed 
posteriorly into short pointed processes. The presence of Hucalanus 
elongatus in the Moray Firth is also of interest as bearing on the question 
of the distribution of species. These copepods are probably carried into 
the estuary by regular tidal currents or by temporary currents set up by 
the wind, should it happen to blow from one particular direction for a 
more or less lengthened period. 
Neither of the two species named have yet been observed in the Firth 
of Forth or the Firth of Clyde. These two estuaries, though extending 
for a considerable distance inland, are comparatively narrow, and the 
entrance to each is obstructed to some extent by an island; the Moray 
Firth, on the other hand, presents an extensive opening to the North Sea 
and narrows very gradually westwards. Such a difference in the general 
contour of these inlets has probably a more or less distinct influence on 
the distribution of their local faunas. 
Paracalanus parvus (Claus). 
1863. Calanus parvus, Claus, Die freileb. Copep., p. 178, Pl. 
XXVI, figs. 10-14; Pl. XXVII, figs. 1-4. 
This small species has been observed in gatherings collected during 
the past year both in the Clyde and Loch Fyne, and usually in bottom 
tow-net gatherings. It was, for example, observed in a bottom-gathering 
from Station V. (Whiting Bay, Arran), collected September 8th, and in 
another from Station XVII. (near the head of Loch Fyne), collected 
September 29th. 
Stephus fultont, T. and A. Scott. 
1898. Stephus fultont, T. and A. Scott, Ann. and Mag. Nat. 
Hist. (7). vol. 1, p. 185, Pl. X., figs. 1-8; Pl. IL, figs. 1-4. 
Stephus fultont has apparently not yet been observed outside the Clyde 
area. It was first observed in 1896 in some material dredged in Kil- 
brennan Sound, and subsequently in a small gathering of crustacea 
collected near the Spit, Loch Fyne, in 1897. I have now to record its _ 
occurrence for the second time at this Loch Fyne Station ; the material 
in which it was obtained on the present otcasion was collected during the 
early part of this year (1899), and a few ‘specimens only were observed. 
Stephus fultont, which seems to be a rare species, 1s comparatively easlly 
distinguished from the other members of the genus by the somewhat 
larger size of the female and by the male having the fifth thoracic feet 
conspicuous and furnished with horn-coloured processes. 
Bradyidius armatus (Vanhoffen). 3 
*1897. Bradyanus armatus (Vanhoffen in:) Chun, Arkt. antarkt. 
Plankton, p. 28. 
It was pointed out in my “ Notes” last year that Bradyidius armatus 
was one of the more widely diffused of the Clyde copepods, and that it 
was also occasionally observed on the East Coast. During the past year
