182 PROFESSOR CHARLES CHILTON ON THE 



1904 Mr Walker added another species, A. tenuipes, from Ceylon, for which 

 he established a new genus, Vijaya; but Mr Stebbing (1910a, p. 570) has pointed out 

 that the difference in the male and female antenna3 on which the genus was founded 

 occurs also in Amaryllis, and that the new genus is therefore not required.

Station 414, lat. 71° 50' S., long. 23° 30' W. ; 8 ft. vertical net, from the surface 

 to 1000 fathoms. 15th March 1904. One specimen, total length 20 mm. 



This specimen in all probability belongs to this species, although it diflers from the 

 description given in Das Tierreich in several minor points. The first segment of the 

 perseon is more produced in front and much more acute than is shown in Stebbing's 

 figure of the Challenger specimen ; the antennse have more numerous joints in the 

 flagella ; there is no accessory flagellum to be seen in either of the up23er antennae — 

 possibly it has been broken off, though I can detect no trace of this. The first and 

 second perteopods (fig. 3) are simple or almost so, the propod being only very slightly 

 widened and the finger apparently not folding back upon it. The basal joints of the 

 third to the fifth perseopods have the margins less serrated. 



The gnathopods (figs. 1 and 2), the uropod, and the telson agree fairly well with 

 C anonyx, which has been already recorded from Tristan da Cunha in the South Atlantic, 

 and I think the Scotia specimen is only a larger and more fully developed specimen 

 of that species. The whole integument is soft, there is no sign of eyes, and the animal 

 was probably taken at a considerable depth. It is interesting to note that in 1903 

 Mr Walker stated that this species would probably be found to occur in Antarctic seas. 

 It is also found in the seas of the northern hemisphere.
