Specimens from the third, fifth, and eighth stations are all 

 of comparatively small size and have reddish brown eyes, 

 while in specimens from the other stations, whether large or

 species N. longirostris, the dorsal teeth very numerous, to the 

 rear closely packed, but widely separated forward, where they

Ovum, and larvae from ova of Nematocarcinus, sp.

 rostrum, which measured 18 mm. Another specimen with 

 carapace 30 mm. long has a rostrum 14 mm. in length. This
