Anomalocera Patersonii, Templeton. — East Loch Tarbert and Loch 

 Fyne (Calderwood). This copepod is at times moderately common in 

 Lower Loch Fyne. 



Parapontella brevicornis (Lubbock). East Loch Tarbert and Loch 

 Fyne (Calderwood). 



Acartia Clausii, Giesbrecht. — Head of Loch Fyne, between Carndow 

 and Ardno. Off Inveraray, and in the vicinity of Minard (G.). Upper 

 Loch Fyne, in 30 to 70 fathoms, as Dias longiremis (M.). ?East Loch 

 Tarbert as Dias longiremis (Calderwood). I have examined speci- 

 mens of Acartia from various parts of Upper and Lower Loch Fyne, and 

 A. Clausii is the only species that has yet been observed in this part of 

 the Clyde area. 



Paramisophria, nov. gen. — Somewhat like Misophria in general ap- 

 pearance. Antennules short, and composed of about twenty-one joints. 

 Antennae, with the primary branch short, three-jointed ; secondary 

 branches longer than the primary, and two-jointed ; mouth organs as in 

 the Calanidce. Swimming feet nearly as in Pseudocyclops ; both branches 

 three-jointed. Each part of the fifth pair consists of a more or less simple 

 two-jointed branch. 



This genus, though apparently a true member of the family Misoph- 

 riadai, differs from the two genera Misophria and Pseudocyclops, most 

 closely allied to it, in the structure of the antennae and of the fifth pair of 

 thoracic feet. 



Paramisophria cluthce, nov. spec. (PI. II., figs. 3-8; PI. III., figs. 13- 

 16). Description of the female — length, 1'4 mm. (j^th of an inch). 

 Body, robust ; abdomen, short ; only about one-fourth of the length of 

 the cephalothorax (fig. 13, PI. III.). Antennules short; twenty-one 

 jointed ; joints very short (fig. 14, PI. III.). The formula shows approxi- 

 mately the proportionate lengths of all the joints : —

Antennae short, three-jointed, end joint small ; secondary branches con- 

 siderably longer than the primary branches, and composed of two 

 elongate sub-equal joints (fig. 3, PI. III.). Anterior foot-jaws four-jointed, 

 stout, the second and last joints short ; the first and second joints, with 

 a few small papilliform and setiferous appendages on the inner aspect ; the 

 end joint is furnished with a number of long plumose setae (fig. 4, PI. II.). 

 Posterior foot-jaws elongate, moderately stout, (?) seven-jointed, first two 

 joints large and sub-equal, the third, fifth, and sixth small, and of nearly 

 equal length, fourth joint about one and a half times the length of the 

 preceding joint, the (?) seventh is very minute ; the three last are strongly
