Third uropocl, rami subequal, scarcely longer than peduncle. 



Length : <$ 4 mm., $ 5'5 mm. 



Colour : Whitish with grey transverse speckled bauds. Eyes 

 black. 



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

 5 ovigerous $ ? and 5 immature ; St. James (False Bay). 15/2/14. 

 (K.H.B.) 2 cJrf, 13 ovigerous ? ?. (S.A.M. Nos. A2898 and 

 A2958.) 



In possessing ventral spines this species approximates to the 

 Mediterranean species L. spiniventris (Delia Valle), although 

 perhaps this feature is present in other species but has been 

 overlooked. 



The 6th joint of the 1st gnathopod in J is somewhat similar to 

 that of L. kergueleni, but the 2nd joint of 2nd gnathopod is not 

 expanded as in the latter species. 



From the other Cape species L. hirsutipes Stebb. it is easily 

 distinguished by the 1st gnathopod in both sexes, the hook-like 

 prominence on 2nd joint of 2nd gnathopod of ^ , and the absence 

 of setae on the 2nd peraeopod of .

The single specimen corresponds fairly well with Haswell's description 

 of his Microdeutopus australis (Proc. Linn. Soc. N.S.W. vol. 4, p. 271, 

 pi. 11, fig. 5), except in two points, namely: the second gnathopod 

 has the palm of the 6th joint concave, the angle which it makes with 

 the inferior margin blunt, not produced, and furnished with 1 spine; 

 the presence of a large forwardly curved spine on ventral surface of 

 peraeon segments 3 and 4, a small one on segments 5-7, and a small 

 backwai'dly directed tubercle on segment 1. 



Other features of the present specimen are : 



First antenna, 3rd peduncular joint ^ 2nd, accessory flagellum 

 equal to 3rd peduncular joint and longer than 1st flagellar joint, 4- 

 jointed, lst-3rd joints increasing in size, 4th joint | 3rd. 



Mouth-parts, mandibular lobes of lower lip are acute and much
