Part III. — Fifteenth Annual Report 



setiferous (fig. 5, PL IT.). Swimming feet are somewhat like those of 

 Pseudocyclqps, both branches are three-jointed and furnished with 

 numerous plumose setae on the inner margins; in the first pair the mar- 

 ginal spines are slender (fig. 6, PI. II.). In the fourth pair the spines are 

 short, stout, and sabre-like (fig. 7, PI. 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, PI. 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, PI. III.). Male unknown. 

 Habitat — Off' Largabruach, Upper Loch Fyne ; dredged. 



Misophria pallida, Boeck. — Dredged near Largabruach, Upper Loch 

 Fyne (G.). 



Tlwrellia 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 ; and also near Largabruach ; in 

 dredged material (G.). 



Cyclopina gracilis, Claus. — This species has been obtained in Loch 

 Gair \ and also off Inveraray, Upper Loch Fyne (G.). 



Oithona(?) similis, Claus. — East Loch Tarbert and Loch Fyne (Calder- 

 wood). Off 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 

 East 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 bran "trial chamber of large Ascidians from East Loch 

 Tarbert (Mihi).
