It appears that alcyonarians were secured from 75 stations during 

 the cruise. The greatest yield was from station 4936, at a depth of 

 103 fathoms, where 16 species were secured; the next best haul being 

 from station 4894, with a yield of 11 species. This last was almost 

 equaled at station 4935, where 10 species were dredged. Other good 

 hauls were from station 4893, where 8 species were secured; and 

 station 5070, yielding 8 species. All of these extraordinarily suc- 

 cessful hauls were from depths ranging from 95 to 108 fathoms, and 

 all were in Japanese waters. 



The deepest haul was near Bermg Island, where Helicoptilum 

 rigidum, a species for which a new genus of pennatulids is described, 

 was secured from a depth of 2,700 fathoms. At station 4766, near 

 Koniuji Island, one of the Aleutian Group, in a depth of 1,'^66 fathoms 

 Pennatula acuUata and Bathygorgia profunda were secured. At sta- 

 tion 4765, Anthoptilum murrayi was dredged from 1,217 fathoms, and 

 at station 4780, Plumarella spicata and Leptogorgia heringi from a 

 depth of 1,046 fathoms. These were the four deepest hauls at which 

 Alcyonaria were obtained. Of the 6 species from these depths, 3 are 

 pennatulids, and 3 belong to the Gorgoiiacea, while all belong to families 

 of wide distribution in the deep seas.
