The rami of third uropod broadly ovate, 24 times as long as wide, 
apices rounded (cf. those of A. pacifica Holmes). 
Length: 10 mm. (S.A.M. No. A159.) 
AMPELIsca sp. ? No. 2. 
This specimen (Beacon E. of East London N. } E., distant 10 miles. 
52 fathoms. s.s. “ Pieter Faure.” 12/7/01.) differs from A. brevi- 
cornis only in the non-produced 4th joint of Ist peraeopod, the quad- 
rate postero-inferior angle of 3rd pleon segment, with a slight notch 
and shortly produced point, and the broadly ovate rami of 3rd uropod, 
with apex of inner ramus hook-like and incurved. Mandibular palp 
with 2nd joint linear, 5rd equal to 2nd. 
Length: 8mm. (S.A.M. No. A2748.) 
It bears some resemblance to A. californica Holmes.

These specimens resemble the description and figures of Sars except 
in the following points: 2nd joint of mandibular palp of nearly same 
width throughout, the basal half being only slightly wider, 3rd joint 
not half as long as 2nd; outer plate of maxilliped with only 9 broadly 
lanceolate (instead of 14 narrow lanceolate) spines; 6th joint of Ist 
and 2nd peraeopods proportionately longer, being almost twice as long 
as 5th, 7th longer than 5th but shorter than 6th; transverse rows of 
‘spines on 5th joint of 3rd and 4th peraeopods fewer and containing 
fewer spines in each ; postero-inferior angle of 2nd joint of 5th peraeo-
