St. 4. 30. i. 25. Off Tristan da Cunha, 40-46 m. i specimen. 



St. 399. 18. V. 30. Off SW point of Gough Island, 102-141 m. 10 specimens.

St. 941. 20. iii. 32. 40° 53' S, 174° 47' E, Cook Strait, New Zealand, 128 m. 2 specimens. 



St. 1 187. 18. xi.33. Off Tristan da Cunha, 1 17-106 m. Several specimens.

I do not see any possibility of distinguishing the Amphipholis from the Magellanic 

 region from the cosmopolitan A. sqiiamata. Studying the descriptions given of A. pata- 

 gonico I cannot find any other differences pointed out than that the scales of the dorsal 

 side of the disk are somewhat coarser in A. patagonica. But in this regard specimens of 

 A. sqiiamata vary rather considerably, so that it is impossible to base a specific distinction 

 upon this character. A direct comparison of the fine specimen from the Magellan Strait 

 (St. 724), the type locality oi A. patagonica, with specimens oi A. sqiiamata from England 

 or Iceland does not reveal any difference at all. Nobody would be able to distinguish 

 specimens from the Magellanic region from A. sqiiamata, if subjected to him for identi- 

 fication without knowing whence they came. The only reasonable course then is to give 

 up a " species " which cannot be distinguished, and acknowledge it as identical with the 

 cosmopolitan A. sqiiamata. 



Amphipholis nudipora, Koehler

 figs. 15-16. 



St. 279. 10. viii. 27. Off Cape Lopez, French Congo, 58-67 m. 3 specimens. 



Like the specimens on which Koehler based his description of this species, the present 



specimens lack the disk, the character of which thus still remains unknown. But the 



characters of the mouth frame and the arms are quite sufficient for recognizing this very 



distinct species.

I do not see any possibility of distinguishing Lyman's Ophiostigma africanum from his 

 Ophiocnida abnormis. This may sound rather peculiar, since they are referred to two 

 separate genera; but, as set forth by Verrill {op. cit.), the genus Ophiocnida as used by
