apex, the defining angle of palm rounded and somewhat produced, 

 palm transverse, finger and unguis tapering evenly. 



Second gnathopod in $ also as in Delia Valle's figure of that of M. 

 jHifniata but far more setose along palm and hind margin and on inner 

 surface, finger stout, apex subacute and resting in a small pit ; in $ 

 not so large as in $ , palm a little oblique, with a small defining 

 tooth, finely crenulate, finger not closing on to inner surface, apically 

 acute. 



First and second peraeopods slender, 2nd joint longest, 4th a trifle 

 longer than either 5th or 6th, which latter are subequal, inner margin 

 of 5th with 5 spiuules, of 6th with 6 pairs of spinules, finger and uugnis 

 short and stout. 



Third to fifth peraeopods much stouter than 1st and 2nd peraeopods, 

 2nd joint expanded, oval, hind margin straight with very faint serra- 

 tions, postero-inferior angles rounded, reaching to middle of 3rd joint, 

 4th joint longer than 5th, 6th longer than 4th, moderately spinose, 3rd 

 peraeopod shorter than 4th or 5th. 



First and second uropods, peduncle with spine at apex, rami sub- 

 equal. 



Third uropod long, outer ramus spinose, with a distinct though very 

 small second joint, inner ramus ovate, apically acute, inner margin 

 with 3 spines. 



Length: $ 18 mm. (to end of 3rd uropod), $ 10mm. 



Colour : Greyish, each segment with one or two transverse bands of 

 purplish grey, peduncles of antennae purplish, peraeopods ringed with 

 the same colour. 



Locality: St. James (False Bay) and Table Bay. 1897. (Dr.W.F. 

 Purcell) ; Sea Point, near Cape Town. 19/3/14. (K.H.B.) ; Port Eliza- 

 beth. Nov. 1914. (F.W.FitzSimons); East London. July, 1914. (E.M. 

 Lightfoot). 3 $ and ovigerous $ $ . (S.A.M. Nos. 1273, 1291, 

 A2892, A2900, A2905, A3056, and A2907). 



Geogr. Distribution : New Zealand (Dana, Thomson, Miers, Chilton) ; 

 Ceylon (Walker) ; Ceylon (Stebbing, M. zeylanica) ; Auckland, 

 Chatham, and Kermadec Islands (Chilton) ; Falkland Islands 

 (Stebbing). 



For the present inaequistytis may be kept sepai'ate from palmata on 

 account of the shape of the 2nd gnathopods in $ , but there is no 

 doubt that eventually it must be merged into the latter. The teeth on 

 the pleon of the South African specimens agree exactly with Stebbiug's 

 description of palmata.
