REPORT ON THE AMPHIPODA. 1513 



ramus not very elongate, but having several setae below the cleft spine ; joints of the 

 rami twelve or thirteen in number. 



Uropods. — Peduncles of the first pair much shorter than the rami ; the rami long, 

 three-sided, strongly pectinate on two edges, the outer narrower than the inner but 

 about equal to it in length, the apex of each acute, free from teeth ; peduncles of the 

 second pair a very little shorter than those of the first, much shorter than the rami ; 

 the rami thinly laminar, smooth, with rounded apices, reaching beyond those of the first 

 pair ; the peduncles of the third pair not longer than broad ; the rami like those of 

 the second pair, but the outer rather shorter than the inner, and the apices more broadly 

 rounded. 



Telson broad at the base, arched in outline, longer than broad, about two-thirds 

 the length of the inner ramus of the third uropods, the acute apex not quite reaching the 

 apices of the first uropods. 



Length, about nine-twentieths of an inch. 



Localities. — October 5, 1873, South Atlantic; lat. 29° 1' S., long. 28° 59' W. ; sur- 

 face, night ; surface temperature, 65 c> 2. 



Station 230, April 5, 1875; North Pacific, south of Japan; lat. 26° 29' N., long. 

 137° 57' E. ; surface; surface temperature, 68°"5. Two specimens, the one examined a 

 male. 



Remarks. — The specific name refers to the markings of the pleon-segments. The 

 specimen from the Pacific was nearly two-fifths of an inch in length, and differs from the 

 Atlantic specimen very slightly, as in having the elbow more exaggerated in the first 

 joint of the first gnathopods, and in having a still broader first joint to the fifth peraeo- 

 pods. Claus' Eupronoe maculata is from Zanzibar. 



Eupronoe pacifica, n. sp. 



The species bears a general resemblance to Eupronoe minuta, Claus. The first two 

 segments of the perseon are dorsally coalesced, the side-plates of all the seven segments 

 distinct. The postero-lateral angles of the first three pleon-segments are all more or 

 less blunt, those of the third segment well rounded ; the fourth segment about as long 

 as the composite segment which follows it. On many parts of the animal hexagonal 

 markings are conspicuous. 



Upper Antennse. — The three joints of the peduncle successively shorter ; the first 

 joint of the flagellum equal in length to the second and third of the peduncle, broad at 

 the base, rapidly tapering, carrying two transverse bands of four filaments apiece, the 

 second joint cylindrical, shorter than the first, with two filaments, the third joint filiform, 

 much longer than the second.
