466 Part I1T.—Twentieth Annual Report 
as in Cletodes. The copepods for which I have instituted this genus do 
not correspond to any described form known to me. The genus is named 
in compliment to Dr. T. Wemyss Fulton, Superintendent of the Scientific 
Work of the Fishery Board for Scotland. ‘ 
Fultonia hirsuta, T. Scott (sp. nov.). Pl. XXITT., figs. 5-12. 
Description of the Female.—Length about -63 mm, (+, of an inch). 
Body somewhat slender and sub-cylindrical, the posterior margins of 
abdominal segments fringed with short projecting hairs, which give to this 
part of the animal a peculiarly hirsute appearance, caudal furca short, 
rostrum small (fig. 5), 
Antennules rather slender, and shorter than the cephalo-thoracic segment, 
eight-jointed ; the first three joints are moderately large, but the others are 
short; all the joints, with the exception of the first, are more or less 
setiferous; an elongated and slender asthetask springs from the upper 
distal angle of the fourth joint (fig. 6). The approximate proportional 
lengths of all the joints are shown by the formula—

The antenne are similar to those of Cletodes; the secondary branches 
are very small, and one-jointed, and furnished with a single terminal 
hair (fig. 7). 
Mouth organs somewhat similar to those of Cletodes ; the second max- 
illipeds, which are moderately elongated, are provided with long slender 
terminal claws (fig. 8). 
The thoracic feet are all moderately slender; the outer branches of the 
first four pairs and: the inner branches of the second, third, and fourth 
pairs are all three-jointed, while the inner branches of the first pair are 
only two-jointed. All the inner branches are short; those of the first 
pair are just about half the length of the outer branches and carry three 
small terminal setze or spines (fig. 9). The inner branches of the 
other three pairs are scarcely more than a third of the length of the outer 
branches (fig. 10). The outer branches of the same three pairs are 
rather more elongated than those of the first pair. 
In the fifth pair the basal consists of a narrow plate articulated to the 
last thoracic segment, and bearing one or two small marginal sete; the 
exterior extremity of the basal joint is produced into a very narrow lobe 
which forms the base of a small seta. The secondary joints are narrow 
and sub-cylindrical, and about four times longer than broad, and 
furnished with about half-a-dozen small marginal and terminal setz 
(figce 1): 
Habitat.—Station VI., Firth of Forth (off St. Monans), dredged 
in 13 to 15 fathoms, on May 22nd, 1901. 
Remarks.—This species somewhat resembles Cletodes irrasa, T. Scott, 
in its hirsute appearance, but in that species the antennules are six-jointed, 
the inner brancbes of all the first four pairs of thoracic feet are only two- 
jointed, while the caudal] furca are moderately long and slender. The 
species does not resemble any described form known to me.
