third and fourth peraeopods (or one of them) is undulated. 

 This would separate the former from N. cursor, A. Milne- 

 Edwards, with which Alcock in 1901 suggests its identity. 

 Alcock in the same year refers to the close affinity between 

 Bate's N. tcnuipes and the same author's iV'. tenuirostris. But 

 in redescribing the latter he makes no mention of undulated 

 fingers, while of N. tcnuipes Bate expressly says that the 

 fingers are straight. Between his N. lanceopes and his N. 

 longirostris Bate draws the distinction that in the former the 

 eggs are large and oval, but in the latter small and round. 

 Whether the eggs observed were at the same stage of 

 development he does not state. In this genus the large size 

 of the second joint in the second maxillipeds may be worthy 

 of notice, though much the same character occurs in neigh- 

 bouring families. 



Specimens, differing much in bulk, all from considerable 

 depths, and all from the same area of the South African 

 waters, have been sent from the following stations : — 



1. Cape Point N. 81° E. 32 miles; depth 460 fathoms. 

 A 1312. No. 180. 



2. Cape Point E. by N. f N. 34 miles ; depth 480-600 

 fathoms. A 1242. 



3. Cape Point NE. f E. 6 miles; depth 600 fathoms. 

 A 1287. 



4. Cape Point Lighthouse N. 2f E. 36 miles ; depth 

 600 fathoms. No. 179. 



5. Cape Point Lighthouse NE. f E. 36 miles; depth 600 

 fathoms. No. 200. 



6. Cape Point N. 89° E. 36 miles; depth 700 fathoms. 

 A 1243. 



7. Cape Point NE. by E. ^E. 43 miles ; depth 900 fathoms. 

 A 1229. 



8. Cape Point N. 58° E. 49 miles; depth 900 fathoms. 

 A 1290. 



A specimen which has come to light from a ninth station 

 must be reserved for discussion at a future opportunity.
