AMPHIPODA. C HILTON. 85 



The first gnathopod with merus ending acutely at the 

 distal angle; carpus slightly shorter than the propod, 

 posterior margin somewhat lobed and bearing 6 or 7 tufts 

 of long setules; anterior margin with a row of six short, 

 stout setules; propod oval, narrowing distal! y, palm very 

 oblique, slightly concave, defined by a blunt tooth and 

 having an acute tooth about the centre; finger with inner 

 margin serrate. The second gnathopod similar to the first 

 but with carpus shorter, propod rather longer and palm 

 more distinctly concave, with the central tooth small. 



Basal joints of the third to fifth peraeopoda rather 

 narrow, posterior margin in the fifth straight. Third 

 uropoda with rami subequal. Telson with dorsal surface 

 depressed in the median line, raised on each side into 

 narrow rounded lobe, tipped posteriorly with a stout 

 setule (Fig. 13 &). 



Length. About 12 mm. 

 Colo ur. Brownish. 



The mouth parts are normal and agree well with those 

 of the genus, the inner lobe of the first maxilla well 

 developed and bearing numerous long setules. 



I am very uncertain about the position of this species, 

 of which I have seen females only. In the hirsute 

 character of the appendages, the gnathopods and some 

 other points, it agrees with the description given by Stebbing 

 (1906, p. 615) of Eurystheus hirsutus (Giles), but that 

 species is considered by Walker to be the female of 

 Cheiriphotis megacheles (Giles) which differs in the very 

 small size of the inner ramus of the third uropod and in 

 other respects. 



AMPITHOE FLJNDERSI, Stebbing. 

 (Fig. 15 a-d.) 



Ampithoe flindersi, Stebbing, 1906, p. 635, and 1910, 

 p. 616. 



Locality. 40 miles west of Kingston, S'outh Australia, 

 30 fathoms. One female (Reg. No. E. 4862). 



I think this must be referred to Stebbing 's species, 

 although in the absence of male specimens the determina- 

 tion of the species of this genus is very uncertain. 

 Stebbing 's description was based on a single specimen
