Crustacean Fauna of South Africa. 221 



Second peraeopod, 7th joint with a small tubercle in middle of inner 

 margin, uuguis scarcely halt length of 7th. 



Third to fifth peraeopods, 2nd joint expanded, its hind mai'gin in 

 peraeopod 4 nearly straight, in 5 slightly convex, distal part of hind 

 margin and inferior angle slightly serrulate and spinulose. 



First and second uiopods, rami respectively shorter and subequal to 

 peduncle. 



Third uropod, ramus subequal to peduncle. 



Length : 3 17 mni., ? 13 mm. 



Colour : Whitish, eyes dark brown. 



Locality : West and East coasts of the Cape Peninsula. (Dr. W. F. 

 Piircell and E. M. Lightfoot.) ,?<?,?? and young. (S.A.M. 

 Nos. 1527-9, 1284, A2460.) 



This species is very like T. brito Stebbing from the North Devon 

 coast, but possesses certain well-marked features of its own. The 6th 

 joint of the first gnathopod in $ has a narrower process and distal 

 margin is more strongly concave, the palm of the second gnathopod 

 in c? is more transverse, 2nd antenna in $ stouter and telson more 

 deeply incised and more spinose than in T. brito. 



TALORCHESTIA ANCHEIDOS u. sp. 

 (Plate XXVII. Figs. 35, 36.) 



Closely allied to the last species. Body not very broad. Eyes sub- 

 rotund, their distance apart less than their diameter. Side-plates not 

 very deep, 2nd with a strongly produced rounded lobe on upper 

 posterior angle, 5th as deep as 4th, lobes subequal in depth. Postero. 

 inferior angle of pleou segment 3 very slightly produced, posterior 

 margin slightly concave. 



Telson with apical incision, spinose. 



First antenna reaching to end of penultimate peduncular joint of 

 2nd antenna, 3rd joint in $ longer than 2nd (but not equal to 1st 

 plus 2nd), in $ equal to 2nd, flagellum nearly equal to 2nd plus 3rd, 

 6- jointed in $ , 4- jointed in ? . 



Second antenna reaching nearly to end of 3rd peraeon segment in $ , 

 2nd in $ , ultimate joint longer than penultimate, flagellum equal to 

 last two peduncular joints together, 17-jointed in $ , 13-jointed 

 in $ . 



Mouth-parts as in T.quadrispinosa. 



First gnathopod in $ , 4th joint not expanded, 5th strongly ex- 

 panded, the lobe broad and rounded, distal margin only slightly con- 

 cave, Hth shorter than 5th, also strongly expanded, distal margin
