and having a similar pair, but much larger ones, on tlie first 

 coxse ; the second coype nre extremely long. A. hrachyura, 

 Bouvier, is closely allied, but stouter; lateral processes closer 

 together, and the neck is shorter. 

 Several specimens, winter-quarters. 



Ph ox ich iiidi u m a us tra le . 



The presence of a small process or spur on either aide of 

 the proboscis serves to distinguish this species. 

 A few specimens from winter-quarters. 



Palhnopsis pilosa. 

 Phoxichilidium pilosum, Hoek, * Challeoger ' Report. 



This species, first described by Dr. Hoek, has since been 

 found at various points in the antarctic regions by most of 

 the recent expeditions. 



Winter-quarters, 20. iii. 02. 



Pallenopsis vanhoffeni. 



This species is conspicuously setose, but readily distin- 

 guishable from the foregoing by the coarseness of the setre. 

 The cephalic segment is longer than the two following. The 

 abdomen is shorter than the first segment and clavate, with a 

 group of long setpe. 



Three specimens, winter-quarters, 7. ii. 03 and 3. iv. 02. 



Pallenopsis gaussiana. 



This may fairly be called a' conspicuously setose species, 

 and the distinctive feature is the presence of a spine near the 

 antero-lateral margin of the cephalon. Spines also occur on 

 the lateral processes. The abdomen is longer than the first 

 segment. The legs are clothed with long coarse setae, but 

 these vary great! v in length. 



7. iv. 02. 



Pallenopsis meridionalis. 



Body with widely separated lateral processes, wliich, with 

 the first coxas, bear small spines. Segmentation fairly 

 distinct. Long, coarse, and curved seta3 are scattered along 

 the legs, chiefly dorsally. 



Winter-quarters, 7. iv. 02.
