ginal setae in the male being, however, stouter ; the 

 inner segment of the basal joint is broad and large, 

 and of about the same length as the outer segment, 

 which forms a subquadrate plate bearing five seta3 ; 

 the setse of the inner plate are three in the male (fig. 

 12) and five in the female (fig. 11). Caudal segments 

 short, about as long as broad (fig. 13). Inner tail-

Dr. Baird^s specimens of Westwoodia nobilis were 

 obtained in Berwick Bay, at Dover, and the North 

 Foreland. I have found it rarely on Laminarise 

 near Sunderland, and in a depth of two fathoms 

 at Cumbrae ; on weeds between tide-marks at Round- 

 stone ( Galway ) ; Yentry Bay and Mulroy Lough 

 (Donegal), fourteen fathoms ; Portincross, Ayr- 

 shire, ten to thirty fathoms ; also near St. Agnes 

 (Scilly), ten to twelve fathoms. Mr. Norman has 

 noticed it amongst weeds at Oban and at Tobermory 

 (Mull). This, though widely distributed, is one of the 

 less common of the British Copepoda, occurring 

 nowhere in any considerable numbers. Dr. Baird 

 states that the " whole animal is beautifully coloured 

 with green, red, and purple ;" this has not been by any 

 means usually the case with such specimens as I have 

 taken ; but in those sent to me by my friend, Mr. 

 Norman, from Oban where it was found amongst 

 weeds between tide-marks the head, last thoracic 

 somites, and tail are marked with deep brownish red; 

 the eye also is conspicuously large and red.
