204 PROFESSOR CHARLES CHILTON ON THE 



peraeopods. lu these cliarcacters it difFers from L. consanguinea, which has been taken 

 off South Africa and at Kerguelen and Heard Islands. 



Another species, L. lequahilis, described by Stebbing, 1910a, pp. 588 and 638, 

 from Australian seas, seems to be closely allied, and all three species present many 

 points of resemblance to L. fissicornis (Sars), found in the Arctic and North 

 Atlantic Oceans. 



L. duhia is now known from Australia, New Zealand, South Victoria Land, the 

 South Orkneys, and South Africa. 



From Mangareva Island, Gambler Archipelago, M. Chrvreux has described a 

 species, L. proxima, 3 mm. long, which is, he says, very near to L. pallida (Sp. Bate) 

 and L. brevicornis (Bruzelius). It seems also to be very close to L. duhia or to L. 

 xquahilis, the latter of which is, according to Stebbing, in close agreement with 

 L. hrevicoryiis. 



Genus Epimeria. 



Epimeria macrodonta Walker. 



Epimeria viae rodon.ta Walker, 190G, [i. 10, and 1907, p. 24, pi. viii. fig. 14. 



Coats Land, Station 411 ; trap, IGl fathoms; lat. 74° 1' S., long. 22° W. 

 10th March 1904. One specimen, 25 mm. long. 



This specimen must, I think, undoubtedly belong to \yALKER"s species, but it differs 

 a little in the arrangement of some of the numerous teeth. The first segment of the 

 peraeon has a short dorsal tooth and a small lateral tooth ; there are no teeth on the 

 short second segment ; the other segments of the perason and those of the pleon bear 

 dorsal and lateral teeth as described by Walker. The first segment of the urus bears 

 a strong dorsal tooth as described, but on the second segment there is a tooth placed a 

 little laterally on each side on the posterior margin, and there is a lateral carina ending 

 in sharp teeth on the third segment. The first joint of the peduncle of the first antenna 

 bears a long tooth on the under side at the extremity, in addition to the two lateral 

 teeth ; the inner tooth on the second joint is much longer than the outer one. The eye 

 is large, round, and projects as a hemisphere from the side of the head ; in the spirit 

 specimen it is yellowish in colour. 



This species seems to come near to E. loricata Sars, which is widely distributed in 

 northern seas, and appears to difier only in the arrangement of the teeth on the pleon 

 and urus, and in tlie acuteness of the dorsal teeth — points which are probably subject 

 to variation. 



Mr Walker's specimens were from the Winter Quarters of the Discovery in 

 M'Murdo Strait, South Victoria Land.
