long setae, outer ram us a little shorter than inner, with ca. 9 

 spines as well as long setae on outer and apical margins. 



Length: $ 6mm., ? 7'5 mm. ; breadth: $ 2'5 mm., ? 3mm. 



Colour: Whitish, with fairly numerous minute stellate black 

 specks. 



Locality: St. James, False Bay. April, 1901.- 1 ? with em- 

 bryos (Dr. W. F. Purcell), and 29/4/12. 1 tf , 2 ? ? with 

 embryos. (K.H.B.) Amongst the tubes of the reef-building worm 

 Sabellaria capensis, low-tide. (S.A.M. 9857 and A2561.) 



This species resembles very closely L. yardhieri, Stebbing, but 

 differs from the latter in the form of the mandibles, tbe length of the 

 spine on the second maxilla and in having 4 spines, instead of 5, 

 on the 4th joint of the first peraeopod. Moreover, it differs not 

 only from L. gardineri, but from all other species of the genus 

 in the length of the male stylet on the second pleopod. 



This is most probably the same species as the mutilated speci- 

 men briefly mentioned by Tattersall. The smaller number of spines 

 on the uropods of the latter may well be due to injury. Tattersall 

 compares the first maxilla of his specimen with that of L. zeylanica, 

 Stebbing, but in the present specimens it is not so strongly developed, 

 and moreover his specimen is 12 mm. long and is therefore, after 

 allowing for the effects of injury and the method of preservation, 

 considerably larger than the St. James' specimens. 



Tattersall's specimens came from Saldanha Bay, 8-10 fathoms.
