Pycnogon'ida collected hy the 'Gauss.' 143 



the range o£ variation is gveat, the ociihir tubercle differs in 

 most of the specimens, the length of the tarsus and propod is 

 is variable even in the same individual, but the differenc -s 

 are not very great and the relations between the two joints 

 are approximately preserved. The setose character of the 

 limbs is accentuated in some specimens. On the whole, 

 iV. antarcdciim, Miers, only differs in that the tarsus is 

 distinctly longer than the propodus. 



In iV. meridionale I find it even more difficult to decide. 



CHiETONYMPHON. 



Chcetonymphon villosiim, 

 Cheetonymphon villosum, Hodgson, ' Discovery.' 



This is a stoutly built species, with the lateral processes 

 close together and long coarse seta3 distributed over the body 

 and especially on the tibia. The three terminal joints of the 

 palps 6 — 2 — 3. 



Specialized spines on the ovigers are few in number and 

 have .5-7 teeth. The auxiliary claws are small but distinct, 

 the propodus is longer than the tarsus. 



31.xii. 02. 3S5 m. 



One specimen, 



Chcetonymphon polare. 



Another stoutly built species, with lateral processes dis-

Oviger : specialized spines few, eacli with 5 or 6 lateral 

 teeth. 



Legs armed with spines arising from dermal papillae. 



Propodus shorter than tarsus, auxiliary claws small. 



7-8. ii, 03. 350 m. 



Chcetonymphon longisetosum. 



Body with narrowly separated Literal processes, imperfect 

 segmentation, antl long setse. 



Palp, three ttrminal joints 5 — 1*8 — 2"75. 



Very long setaj on the principal joints of the leg, a very 

 definite specific character. 



Propodus longer than tarsus, auxiliary claws small.
