160 Anna!* of the South African. Museum. 



Third peraeopod resembling '2nd (chelate in 3 , simple in 2 ) but 

 the keel oil posterior (upper) margin of 2nd joint, indented in middle, 

 more strongly so in $ than 2 , a seta in the indent, the whole margin 

 of keel minutely crenulate, 4th to 6th joints rather densely setose 

 in $ . 



Fourth and fifth peraeopods similar to 1st, keel on 2nd joint 

 crenulate and emarginate in middle, 4th to 6th joints densely setose 

 in <? . 



Branchial lamellae narrow, apically rounded, margins not setose. 



Marsupial lamellae oval, apically rounded, setose. 



First to third pleopods in both sexes decreasing in size posteriorly, 

 but not at all degenerate, peduncles with inner apices produced as 

 narrow lobes (longest in the 1st pleopod) bearing 4 hooked spines. 



First uropod, peduncle straight, cylindrical, ramus shorter than 

 peduncle, narrow, apex with a short blunt spine, upper outer margin 

 very finely and regularly pectinate, inner apex of peduncle with a 

 short blunt tubercle probably representing the inner ramus. 



Second uropod in $ reaching as far as 1st, peduncle stout, upper 

 margin concave, a blunt lobe at upper outer basal angle, another at 

 lower apex and another at upper inner apex, this latter bearing a 

 tubercle (representing the inner ramus), ramus short and very stout, 

 apically rounded, upper margin of peduncle and ramus with a few 

 setae ; in 2 not quite as long as 1st uropod and not stouter, only the 

 lobe on inner apex present, ramus as in 1st uropod with marginal 

 pectinations and apical spines. 



Third uropod reaching just beyond other uropods in $ , not quite 

 as far in 2 , rapidly tapering to an acute apex, limits of peduncle and 

 ramus observable on the margins, but no trace of a transverse suture, 

 margins setulose, 1 apical seta. 



Length : (Pleon flattened out) 3 7 mm., 2 4 mm. , breadth : 

 (including side-plates) $ 3 mm., 2 2 mm. 



Colour : Pale salmon or buff with numerous circular pink spots, 

 each with a pale centre and a darker circumference, on head, side- 

 plates, lateral portions of peraeon segments, pleon and basal joints of 

 limbs, the largest being the submediaii row on the peraeou, and of 

 these the two on the 4th segment are the most conspicuous. Eyes 

 black. 



Locality : St. James and Kalk Bay (False Bay). July, 1896. 

 2 nonovigerous 2 2 (Dr. W. F. Purcell) and 11/8/12. $ $ and 2 2 

 with ova and embryos (K.H.B.). On underside of boulders at low- 

 tide. (S.A.M. Nos. 8828, A114 and A2893).
