Besides this species was talven by the "Albatross " in 1899 at a single place : — 

 Hyd. Sta. 3789. Sept. 9, 1899. Lat. 2° 38' N., long. 137° 22' W. Surface. 

 3 specimens. "Albatross." 



Distribution. — This slender and small species, which has only been taken 

 at the surface, is known from the Bay of Bengal (the author), is common in the 

 Indian Archipelago ("Siboga"), and from here it is, according to the literature, 

 distributed across the Pacific in its tropical area; Sars has mentioned it from 

 the North Pacific. It has never been taken in the Atlantic.

Butaritari, Gilbert Islands, Jan. 6, 1900. Lagoon. Surface. Light. 9 specimens (1 adult male, 

 8 immature specimens). "Albatross." 



Remarks. — The presence of an adult male rendered it possible to determine 

 the species. The strong setae of both rami of fourth pair of pleopods agree in 

 every main point and even in most of minute particulars with my drawings 

 (figs. 3e and 3f) in the paper quoted. The proximal joint of each exopod of 

 the uropods with only 13 spines. The male is 9.5 mm. long. 



Distribution. — S. media was hitherto known only from seven places in 

 the Indian Archipelago ("Siboga").

Sta. 4592. Oct. 13, 1904. Lat. 18° 20' N., long. 103° 40' W. Surface. 1 specimen. 



Sta. 4619. Oct. 20, 1904. Lat. 7° 15' N., long. 82° 8' W. Surface. 7 specimens. 



Hyd. Sta. 3789. Sept. 19, 1899. Lat. 2° 38' N., long. 137° 22' W. Surface. 1 adult female. 



Remarks. — A couple of specimens are adult males, and the largest is 10.4 

 mm. The sexual setae on the endopod of fourth pleopods nearly as on fig. Ih 

 in the "Siboga" paper, but the longest inner seta slightly overreaches the 

 terminal, consequently intermediate between fig. Ih and fig. If.
