First to third pleopods with 4 hooked spines on inner apex of 

 peduncle. 



Second pleopod, male stylet extending beyond apex of ramus, 

 narrow, tapering to an acute apex. 



Uropods, inner ramus narrow oblong, apex bifid, with rounded 

 inner apex, a longitudinal row of 6 tubercles down the centre (but 

 the number is subject to variation) ; outer ramus lanceolate, apex 

 acute, turned outwards, without tubercles ; both rami extending a 

 little beyond telsonic apex. 



Length : $ 17 mm., ? 16 mm. ; breadth : $ 9 mm., ? 8 mm. 



Specimens from Kalk Bay and St. James measure : $ 11x5 mm., 

 ovigerous ? 9x4'5mm. 



Colour : Brownish grey, some or all of the tubercles of a sienna- 

 brown or sometimes orange-brown.

 " Pieter Faure." Kalk Bay, False Bay. 26/5/96. (K. M. Lightfoot.) 

 2 ovigerous $ ? . Sea Point, near Cape Town. Nov. and Dec., 

 1913. (K.H.B.). .S3, ovigerous 5 ? and immature specimens. 

 St. James, False Bay. 15/2/14. (K.H.B.) 2 $$,l 2 and 

 young. Also 2 $ $ , 1 ovigerous 5 and 1 young $ from the 

 "Pieter Faure " collection without locality. (S.A.M. Nos. A49, 

 A262, A2647, A2679 and A2455 respectively.) 



They are found at low-tide occasionally under stones, but most 

 frequently in the holes and crevices of the reef-like masses of tubes 

 formed by the worm Sabellana capensis. 



On sending specimens of this species and of the species which I 

 took to be the true Sphaeroma scabricula of Heller to Dr. H. J. Hansen, 

 he informed me that my surmise was correct, that he had not seen 

 the true scabricula and that the species to which he referred on 

 pp. 102, 103, 116 of his Eevision of the Sphaeromidae was in reality 

 the present new species. This justifies the above synonymy. 



DYNOIDES, n. g. 



Maxillipeds with 4th, 5th and 6th joints inwardly produced. 

 Anterior peraeopods without natatory setae. Outer ramus of 3rd 

 pleopod unjointed. Outer ramus of 4th and 5th pleopods mem- 

 branous, without folds, 2-jointed. Seventh peraeon segment un- 

 armed. Pleon (4th ? segment) with median process. Telson
