AMPHIPODA — STEBBING. 589 



apical notch of each lobe. The outer lobe of the notch is not 

 longer than the inner. The telson itself is rather more than 

 twice as long as the greatest breadth. 



Length of one specimen about 9 mm.; of the other, a female, 

 about 14 mm. 



What value for specific distinction should be attributed to the 

 presence or absence of small dorsal cusps and similar minutiae 

 is still an open question''^. The question exercised a soporilic 

 influence on my mind, so that in describing Liljehorgia for " Das 

 Tierreich " it was only at the last moment that I thought of men- 

 tioning L. aequahilis. Again, in dealing with the " Thetis " 

 specimens I had chosen a new name for them before recalling 

 their agreement with the species already described from South 

 Australian waters. Thus, whatever my doubts, on two indepen- 

 dent occasions I have been led to regard this form as a distinct 

 species.

In 1906 Mr. Walker added to the genus the large species 

 (E. calmani, and in 1907, transferred the species which in 1903 

 he had described as (Ediceros neionesi to (Ediceroides. Both 

 these species differ rather strikingly from the three " Challenger" 

 species by the much less conspicuously developed frontal process, 

 and apparently by the more normal deve]o()Uieiit of the eyes.
