344 DE. H. J. HANSEN ON THE 



2. CiROLANA GALLICA, B. Sp. (PL 33. figS. 1 «-l d.) 



Eyes black, seen from tlie side slightly or scarcely longer 

 than deep, with the upper margin rather convex. 



Frontal plate, clypeus, and antennulse much as in C. horealis. 



Antennae shorter than in the preceding species, reaching almost 

 to second thoracic segment ; flagellum with about twenty-two 

 joints. 



Epimera of second and third thoracic segments with a long, 

 slightly curved, and somewhat oblique furrow besides the sub- 

 marginal one ; epimera of fourth to seventh segments shaped as 

 in C. horealis, but furnished with a very oblique furrow which 

 on fourth to sixth, not on last segment, reaches to their posterior 

 margin. 



Seventh thoracic legs have the second joint strongly flattened 

 and extremely expanded, nearly two-thirds as broad as long, 

 with both lateral margins and the longitudinal ridge on the 

 lower side very closely set along their whole length with long 

 plumose setse. Fourth joint very conspicuously longer than the 

 fifth and slightly shorter than sixth. 



Last abdominal segment with the lateral margins convex, not 

 angular at the beginning of the terminal third ; only two pairs 

 of spines on the distal margin ; the end is sharply angular. 



TJropoda slender. The endopod, which, when parallel with the 

 axis of the animal, reaches a little beyond the end of abdomen, 

 is somewhat more than two and a half but not fully three times 

 as long as broad, without distinct notch near the end of the outer 

 margin. Exopod at least four times longer than broad and 

 considerably shorter than the endopod, with a few (two or 

 three) spines along the outer margin. 



Length : — One of the largest specimens, a male, measures 

 20 mm., but whether the animal is really adult or not cannot be 

 settled. Female with marsupium unknown. 



Occurrence. — Eoscoff, or perhaps Gruernsey or Jersey. A large 

 number of specimens belonging to the maritime station of 

 Eoscoff have been kindly sent to me by Professor Tves Delage. 



MemarJcs. — This species is rather closely allied to C. horealis, 

 but it is easily distinguished by a number of characters, among 

 which those used in the conspectus are very easily observed. 

 C. gallica has in all probability been seen before now and 

 confounded with C. horealis. I think it very likely that it 

 will be found ou the southern coasts of England and Ireland, 

 and on the western coasts of France, Spain, and Portugal.
