Habitat. — Largo Bay, frequent. This species is rather robust, with 
short caudal segments; these and one or two of the last abdominal seg- 
ments are more or less covered with close-set short hairs. 
Cletodes limicola, var. gracilis, Brady. 
Gletodes limicola, var. gracilis, Brady, op. cit., vol. ii. p. 96. 
Habitat. — Largo Bay, off St Monance, and other parts of the Forth in 
company with the type. The caudal segments in this form are long and 
slender, and have a prominent jointed (?) spine arising nearly at right 
angles from the upper surface and near the middle of each segment. I 
have observed both male and female, the latter with ova, in material 
dredged off St Monance in from 12 to 14 fathoms. With the exception 
of the long caudal segments (which are fully two-thirds the length of 
those of C, longicaudata), very little difference can be observed between 
this variety and the typical G. limicola.

Cletodes longicaudata, Brady, op. cit., vol. ii. p. 92, pi. lxxix. figs. 
13-19. 
Habitat. — Off St Monance, rare. This species has long, slender, caudal 
segments, and differs from the G. limicola, var. gracilis, by the form of the 
fifth feet and anterior antennae ; the caudal segments are also longer. 
Enhydrosoma curvatum (Brady and Robertson).

figs. 12-15; pi. lxxxii. figs. 11-19. 
Habitat. — Largo Bay, not uncommon; the extremities of both branches 
of the first feet are furnished with two long slender setae, at the ends of 
which are a few fine flagellum-like hairs. 
Thalestris serrulata, Brady. 
Thalestris serrulata, Brady, Mon. Brit. Cop., vol. ii., p. 133, pi. 
lix., figs. 2-11 (1880). 
Habitat. — East of Inchkeith, several specimens taken with surface net. 
This species was described by Dr Brady from a single specimen — a male 
— dredged on a bottom of muddy sand in New Grimsbay Harbour, Scilly. 
Last year (1889) another specimen — a female — was observed by I. C. 
Thompson in a tow net gathering from Puffin Island.* The Forth 
specimens comprised both male and female, and were of a dark brick-red 
colour, which made them very conspicuous in the tow-netting. Some of 
the coloured copepoda, as Alteutha, retain their colour for a considerable 
time after being in spirit ; but in the case of this Thalestris not a trace of 
colour remained after a few hours immersion. I have obtained this species 
also in Dornoch Firth. This seems to be the first record of it for Scotland.
