AMPHIPODA— STEBBING. 627 



peduncle of the second pair rather shorter than the inner ramus 

 of the first, but much shorter than the inner ramus of the second 

 -at its greatest extension, the outer ramus of the second pair a 

 little shorter than that of the first. As indicated, there is some 

 amount of variability in these lengths, probably due to loss and 

 recuperation, which would naturally most affect the longest 

 ramus, the inner of the second pair. The third pair have in all 

 three forms a short broad peduncle, strongly produced on the 

 inner side. In this species the outer ramus extends beyond the 

 produced part of the peduncle, and may even considerably exceed 

 the whole peduncle in length. This is so different from what is 

 seen in the other two Australian forms that I distrusted my 

 figure and description in the " Challenger " Report, supposing 

 that the rather elongate ramus there given must be the inner. 

 Accordingly in " Das Tierreich" I stated that the outer ramus was 

 " not shown in fig. 125, p. 707," whereas it is certainly the inner 

 ramus that is missing, not only from the figure, but from all the 

 specimens which have come under ray hands. Dana says that in 

 /. ovalis these rami are " quite unequal." His figure shows two 

 rather long slender branches, of which the inner is considerably 

 the shorter. Dana describes the telson as " small ovate," and so 

 it is here, with some minute spinules in notches leading to an 

 acute tip. Length, from front of head to telson, not including 

 uropods, 7 or 8 mm. 



Locality. — Off Manning River, and off Wata Mooli, from 54 to

In this form there are no medio-dorsal projections of the body 

 segments and the postero-lateral angles of the first two pleon 

 segments are only minutely produced. The fifth peraeopod has 

 the second joint not longer than broad as in the preceding 

 species, but with a proximal breadth equal to the length, the hind 

 margin making a broadly rounded bulge at the upper part and 

 then descending rather obliquely but straight to the apical tooth, 

 which is scarcely so much produced as the adjacent tooth of the 

 lower margin. The fourth joint is broad and well furnished with 

 plumose setfe and spines. 



The pleopods have broad peduncles, reaching on the inner side 

 considerably beyond the bases of the rami. Their lateral mar
