Pycnogonida collected hy the '(Janss.^ 1 13 



the ranftc of variiition is great, the ocular tuljcrclc difTers in 

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

 is variable even in the same individual, but the diffcrenc s 

 are not very groat and the relations between the two joints 

 are approximatt'ly preserved. The setose character of the 

 limbs is arccnttiated in some specimens. On tho whole, 

 N. (iiitnrctii'um, Miers, only differs in that the tarsus is 

 distinctly longer than the propodus. 



In iV. merid'wnule I find it even more difficult to decide.
