Maxilliped, 2nd joint not very long, inner plate large, subquadrate, 

 2 obtuse teeth and a seta on truncate distal margin near inner angle, 

 distal margin near outer angle finely serrulate and setulose, epipod 

 short, ovate. 



Peraeopod 1 (gnathopod), similar in both sexes, incisive process on 

 thumb of 6th joint rising distally to a rounded bifid apex, 7th smooth, 

 moderately stout, evenly curved. 



Peraeopod 2 slender, 3rd joint very small, 4th longer than 5th, 6th 

 longer than 4th, 7th plus unguis equal to 6th, very slender, the unguis 

 twice the length of joint itself. 



Peraeopods 3 and 4 similar but stouter, 4th and 5th joints subequal, 

 their hinder apices produced. 



Peraeopods 5-7, 2nd joint stout, 4th and 5th subequal, 6th only a 

 little longer than 5th, but more slender, hinder apices of 4th-6th and 

 distal margin of 5th with a recurved unciform process, inferior margin 

 of 5th convex and finely setose, 7th length of 6th, unguis shorter 

 than joint, curved. 



Pleopods developed well in both sexes, rami subequal and furnished 

 with long plumose seise. 



Uropod short, peduncle as long as broad, inner ramus twice length 

 of peduncle, 2-jointed, 2nd joint rather shorter than 1st, outer ramus 

 not quite equal to 1st joint of inner ramus, 1-jointed (perhaps 2-joiuted, 

 but suture very obscure and doubtful). 



Length : Littoral specimens 4 mm., deeper water specimens 6 mm. ; 

 breadth: "5 mm. and '75 mm. respectively. 



Colour : Littoral specimens in life yellowish-white, eyes black ; deeper 

 water specimens in spirit dirty pink, eyes reddish-brown. 



Locality: Sea Point near Cape Town. 26 '2 '14. (K.H.B.) 1 J,

 125 fathoms. 3 specimens ; Lion's Head SE. i E., distant 32 miles 

 (Table Bay). 126 fathoms. 9 specimens living in a sponge covering 

 the gastropod Argobuccinum murrayi (Smith), s.s. " Pieter Faure. 1 ' 

 21/12/99 and 8/3/00. (S.A.M. Nos. A2697, A3824 and A3833.) 



This species is very likely synonymous with Vanhoffen's Heterotanais 

 (?) capensis 1914. Up to the present I have not been able to consult 

 VanhofferTs paper. 



Distinguished from P. batei Sars by the stout peraeopod I with 

 shorter finger and thumb and stronger incisive process on the latter ; 

 from atlanticus Dollfus by the finger and thumb being shorter than 

 the rest of the hand ; and the latter distinction applies to elongatus 

 Dana, though on the whole this species is nearest to the Cape species. 

 P. ignotus Chilton has a 5-jointed inner ramus of the uropod.
