142 BRITISH COPEPODA. 
ginal sete 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 setee ; 
the sete 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- 
seta longer than the abdomen, outer not much shorter. 
Length 3th of an inch (9 mm.). 
Dr. Baird’s specimens of Westwoodia nobilis were 
obtained in Berwick Bay, at Dover, and the North 
Foreland. JI have found it rarely on Laminarize 
near Sunderland, and in a depth of two fathoms 
at Cumbrae ; on weeds between tide-marks at Round- 
stone (Galway); Ventry 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.
