2S() THE SCHIZOPODA. 



Remarks. — It may be Dieiitionwl that one of the specimens from Sta. 

 4637 has an Epicarid on the lower side of the thorax between the posterior legs. 



Distribution. — The list of Stations shows that *S'. longicornc is rather com- 

 mon in some parts of the area explored in 1904-1905, but seems to be wanting in 

 other parts, for instance near the Galapagos, in a rather large field Southwest 

 and South of these Islands, and in a broad longitudinal belt along the coast of 

 South America. Tlie specimen from the Hawaiian Islands referred (1905) 

 by Ortmann to S. suhniii belongs to S. longicornc. This species was gathered 

 by the "Siboga" at nine Stations in the Indian Archipelago. Sars's type was 

 taken South i)f the Cape of Ciood Hope, and Sars states that he had some speci- 

 mens from the Mediterranean. In the Atlantic it is evidently not uncommon 

 and has been captured as far northwards as South of Iceland, Lat. 63° 08' N., 

 long. 21° 30° W. ("Ingolf " Exp.). — It has very rarely been taken at the surface.

Sta. 4689. Dec. 12, 1904. Lat. 24° .5' S., long. 100° 20' W. 300 fm.s. to .surface. 1 specimen. 



This slender species is easily recognized by its extremely long sixth abdomi- 

 nal segment. Sars's description and figures are imperfect as to some particulars, 

 but a new representation based on good material must be postj^oned for the 

 report on the Monaco material. 



Distribution. — Only the single above-named sj^ecimen is hitherto known 

 from the Pacific, and it is unknown from the Indian Ocean. Sars's two speci- 

 mens were from the South Atlantic. Ortmann had it from se\'eral areas in 

 the Atlantic, viz. : — the Floritla current. Sargasso Sea, Northern equatorial cur- 

 rent, Guinea current and Soutliern equatorial cm-rent. In 1905 I enumerated 

 a number of localities in the Eastern Atlantic between Lat. 36° 17' N. and Lat. 

 27° 43' N. 



c. Species with the elongated pair of legs terminating in real chelae ivith a loell- 

 developcd immovable finger from the pcnidlimatc joint.
