AMPHIPODA. 9 



EUTHEMISTO GAUDICHAUDI. 

 Euthemisto gavdichaudi, Gruerin. 



Abundant from lat. 54° 01' S., long. 170° 49' E. to lat. 63° 04' S., long. 175° 43' E., 

 mostly young — a female with ova measured 15 mm. 



FAM. ANCHYLOMEEIDtE, Bovallius. 



EUPRIMNO MACROPA. 

 Euprimno macropa, Guerin. 



One specimen, length 16mm., 26 Feb., 1904. 



FAM. HYPERIOPSIDiE, Bovallius. 

 Hyperiopsis australis. (PL 4, fig. 3.) 



Hyperiopsis australis, A. 0. Walker, Ann. and Mag. Nat. Hist. XVII. (1906), p. 454. 



W.Q., 16 June, 1903, 15 fm. ; one. 



Differs from //. Voringii, G. 0. Sars (Norweg. N. Atlantic Expn., p. 231), in the 

 following points : — 



The lower margin of the head is oblique. 



The first segment of the urosome has a deep dorsal depression ; the second 

 segment is the longest of the three. 



The third joint of the first and second perseopods is not quite twice as long as the 

 next two united, and is about the same width, i.e., the margins are parallel, the distal 

 three-fourths of its length. 



In the last perseopods the jointing is indistinct, the very long third (or fourth) 

 joint is finely serrate and spinulose. 



The first and second uropods are biramous. In his definition of the genus Sars says 

 that they are " simple, two-jointed," but as the rami cling closely together this might 

 easily be an oversight. 



The single specimen was not dissected (nor, probably, was Bars'), but the 

 maxillipeds are evidently of the Gammarid type. Bovallius (Amphipoda Synopidea) 

 has placed the genus in his tribe of Synopidea under the family Hyperiopsidse.
