256 Southern Cross. 



Maxillipede. Inner margin of masticatory lolje straight, distal 

 and outer margins rounded. Distal part setose, the lateral and outer 

 setae being comparatively long and slender, those near the inner 

 angle being stout and spinose. Palp of the normal number of 

 joints, the meros enormously broad. The carpus bears a large 

 ploughshare-like expansion on its inner margin ; the edge of this, 

 and to some extent the sides, bear stout setae. The propodos and 

 dactylus are normal, and both bear setae distally. 



The epignath is large, roughly semicircular. 



Thoracic appendages. The first is missing. The three following 

 are more distinctly ambulatory, and increase in size passing poste- 

 riorly. They are slender, and the first is almost devoid of setae ; the 

 second is provided with long setae throughout its length, and has 

 the basis, ischium and meros somewhat swollen. The third is 

 attenuated, and is poorly provided with small setae, except at 

 the extremity of the various joints. The ischium, however, bears 

 numerous delicate spines. 



The three posterior appendages present a different appearance, 

 and are sub-equal in length. In the first the basis, ischium and 

 carpus are much swollen ; in the second the carpus only is thus 

 modified ; both limbs are provided with long setae. The joints 

 of the last appendage do not present any striking feature. 



The uropods are minute, and are concealed from the dorsal aspect 

 l»y a slight projection of the pleon. 



Two specimens of this species were obtained off Cape Adare, in 

 26 fathoms. Temperature 28*8° Fahr. 



COPEPODA. 



Two genera of Calanids were taken with Euinlmuda glacialis in 

 lat 65° 52 S., long. 162° 32 E., between the ice floes ; temperature, 

 31° r. They were in a terribly bad state of preservation, much 

 macerated and unfit for description. 



PYCNOGONIDA. 



Of the large number of specimens obtained by the ' Southern Cross ' 

 Expedition, all may be referred to a single species, and that, as might 

 be expected from the locality, a new one.
