bears only a small, conical tooth near hinge, and a smaller conical one 
lower down as in 4, defining angle with 2 spines. 
Telson, ventral plate with 2 submedian spines, dorsal conical process 
bearing 3 large spines on each side of the median one. 
Third uropod as in P. hystrix. 
Length: 9mm. 
Colour: In spirit, pale yellowish, eves brownish.

The above-mentioned characters are constant in the few specimens 
which are available, and would seem enough to separate this form 
from the closely allied New South Wales form P. hystriz. 
PopOCERUS AFRICANUS Qh, Sp. 
(Plate XXVIII. Figs. 24, 25.) 
As the South African specimens agree very closely with Dana’s 
brasiliensis, it will be needful to mention only the points of difference. 
The ultimate peduncular joint of 2nd antenna is a little shorter 
than the penultimate ; 5th joint of lst gnathopod as long as or a trifle 
longer than 6th joint in both sexes ; 4th joint of 2nd gnathopod in ¢ 
strongly and acutely produced ; 6th joint as in P. variegatus Leach, 7.e. 
with 2 strong palmar teeth near the finger hinge; Ist and 2nd peraeo- 
pods with a lobe on anterior distal margin of 2nd joint; 3rd to 5th 
peraeopods with 2nd joint expanded and widest at base, as wide as 
long, distally narrowing ; telson with only 2 spines on dorsal conical 
process (none on ventral plate). 
Other characters as in brasiliensis : flagellum of both antennae 4- 
jointed; pleopods with 2 coupling spines. 
Eyes about in the middle of the lateral margin. Antero-lateral 
angle of Ist peraeon segment quadrate, not produced. 
Length : 5-6 mm. 
Colour : Uniform pale claret.

This species combines the characters of the two species variegatus 
and brasiliensis. These two are closely allied and may eventually be 
united under Leach’s name. The present specimens, however, seem to me 
to be quite distinct in the character of the 2nd joints of the peraeopods.
