great, the ocular tubercle differ in most of the specimens; the length of 
the tarsus and propodus is variable, even in the same individual, but the 
differences are not very great and the relations between the two joints 
approximately preserved. The setose character of the limbs is ac- 
centuated in some specimens. On the whole N. antarcticum Miers, only 
differs in that the tarsus is distinctly longer than the propodus. In N. 
meridionale I find it even more difficult to decide. 
Chaetonymphon villosum. 
Chaetonymphon villosum Hodgson. Discovery, 
This is a stoutly built species, with the lateral processes close to- 
gether and long coarse setae 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 propodysy is longer 
than the tarsus. 
31. XII. 1902. 385 m. One specimen. 
Chaetonymphon polare. 
Another stoutly built species with lateral processes distinctly se- 
parated and fringed with spines. Spinous setae fringing each segment. 
Palps, three terminal joints as 6—2,75—35. 
Oviger specialized spines few, each with 5 or 6 lateral teeth. 
Legs armed with spines arising from dermal papillae. 
Propodus shorter than tarsus, auxiliary claws small. 
7.—8. II. 1903. 350 m. 
Chaetonymphon longisetosum. 
Body with narrowly separated lateral processes, imperfect seg- 
mentation and long setae. 
Palp, three terminal joints 5—1,8—2,75. 
Very long setae on the principal joints of the leg, a very definite 
specific character. 
14.—16. VI. 1902. 385 m. 
Chaetonymphon typhlops. 
Body stout and entirely clothed with fine as well as coarse setae, 
the latter are arranged in a linear manner on the limbs, for the most 
part on raised papillae. There are no eyes but the ocular tubercle exists 
as a short cone. This species DENTS u to the group in which the tarsus 
is longer than the propodus. 
Auxiliary claws are absent. A few specimens were taken.
