148 Part I11.—Fifteenth Annual Report 
setiferous (fig. 5, Pl. II.). Swimming feet are somewhat like those of 
Pseudocyclops, both branches are three-jointed and furnished with 
numerous plumose sete on the inner margins; in the first pair the mar- 
ginal spines are slender (fig. 6, Pl. IL.). In the fourth pair the spines are 
short, stout, and sabre-like (fig. 7, Pl. II.). The fifth pair consists each of a 
single two-jointed branch, the first joint is short, but produced interiorly 
at the distal end into a cylindrical process about as long, and half as broad 
as the joint itself, and provided at the apex with a small spine and an 
elongate plumose seta ; second joint sub-cylindrical, and fully three times 
the length of the first joint, and armed with five stout spines, arranged 
along the outer margin and apex (fig. 8, Pl. II.). Abdomen composed of 
four segments, the last two being together scarcely equal in length to the 
preceding segment; caudal stylets rather longer than the entire length of 
the last two abdominal segments (fig. 16, Pl. IIL). Male unknown. 
Habitat—Off Largabruach, Upper Loch Fyne; dredged. 
Misophria pallida, Boeck.—Dredged near Largabruach, Upper Loch 
Fyne (G.). 
Thorellia brunnea, Boeck.—Head of Loch Fyne between Carndow and 
Ardno ; off Largabruach and Loch Gair, Upper Loch Fyne (G.). This is 
not an uncommon copepod in the Clyde in dredged material. 
Cyclopina littoralis, G. S. Brady.—In the vicinity of Carndow, near 
the head of Upper Loch Fyne; aud also near Largabruach; in 
dredged material (G.). 
Cyclopina gracilis, Claus.—This species has been obtained in Loch 
Gair ; aud also off Inveraray, Upper Loch Fyne (G.). 
Oithona (2) similis, Claus.—East Loch Tarbert and Loch Fyne (Calder- 
wood). O#f Inveraray ; and between Carndow and Ardno (G.). Upper 
Loch Fyne, in 30 to 70 fathoms (M.). 
Notodelphys Allmani, Thorell.—East Loch Tarbert, and Tarbert Bank, 
Loch Fyne, in 20 to 25 fathoms; in branchial chamber of large Asci- 
dians (Mihi). 
Notodelphys agilis, Thorell.—Also found in the branchial chamber of 
large Ascidians collected at extreme low-water in East Loch Tarbert. 
Notodelphys prasina, Thorell.—With the others in the branchial - 
chamber of large Ascidians (Mihi). This species has short caudal 
stylets. 
Doropygus porcicauda, Brady.—A copepod, belonging apparently to 
this species, was obtained in the branchial chamber of Ascidians from 
fast Loch Tarbert, and also from Largabruach, Upper Loch Fyne (G.). 
Though slightly imperfect, the Largabruach specimen resembles this, and 
no other described British species. 
Botachus cylindratus, Thorell.—Obtained in the branchial cnamber of 
Ascidians collected in East Loch Tarbert. 
Notopterophorus papilio, Hesse.—This curious copepod was of frequent 
occurrence in the branchial chamber of large Ascidians from East Loch 
Tarbert (Mihi),
