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. 



Cletodes 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 C. 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 C. 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, Stilly, 

 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.
