274 DISCOVERY REPORTS 



Remarks. Firstly, it seems reasonable to assume that the ? and £ of no. 2 are con- 

 specific, though it is not certain. The most striking feature of both is the very broad 

 peduncles and inner rami of uropods 2 and 3 ; that of the S agrees with Bovallius' figure 

 of a <J. Both specimens further agree with one another in the 2nd gnathopods, though 

 the spines are rather stronger in the $, and in having the postero-inferior angle of pleon 

 segment 3 rounded. 



Apparently the only known $ specimens are those reported by Norman (1900) who 

 says that according to the 1st and 2nd 

 gnathopods both sexes belong to the spini- 

 gera form. The present S of no. 2 has the 

 1st gnathopod as in Bovallius' fig. 34; but 

 the $ has the antero-inferior angle of the 5th 

 joint more rectangular, and with fewer and 

 weaker spines on the 4th-6th joints, in fact 

 quite like that of latreillei as figured by 

 Bovallius (pi. x, fig. 4). 



With these specimens before me, I see

maintaining Bovallius' species as distinct 

 irom galba. 



Bovallius regarded spinigera as an Arctic form, and the most southerly locality yet 

 recorded is the south coast of England. The present specimens extend the known dis- 

 tribution very far to the south. 



It would seem that antarctica is synonymous with spinigera rather than with galba, 

 although one cannot be sure because Spandl merely said the uropods were completely 

 unarmed and showed "keinerlei charakteristische Form". It is just the characteristic 

 form of the uropods which induces me to maintain the distinctness of spinigera. 



Distribution. Spitsbergen; Labrador; West of Ireland; South coast of England; 

 Antarctic (antarctica).

Remarks. In the Terra Nova Report it was stated that this species appeared to be a 

 more Antarctic species than antarctica, as only one of the recorded localities lay north
