The shell of the adult male (see fig. 7) does not differ 

 either in size or shape from that in the female. 



The enclosed animal (ibid.) is, however, at once distinguished 

 by a quite analogous modification of some of its parts as in 

 the male of the preceding species. 



The head, when seen laterally, appears (fig. 8) somewhat 

 shorter than in the female, though not nearly so short and 

 blunted as in the male of L. macleayana. The rostral ex- 

 pansion is rather projected and, as in the latter, transversely 

 truncated at the tip. But the terminal plane surface is 

 narrower than in the male of the preceding species, and is 

 fringed on the edges with rather long cilia. The lateral crests 

 of the head, or fornix, terminate on each side of the apical 

 plane in a well-marked tooth-like projection, best seen, when 

 the head is viewed in front (fig. 1). 



The legs are 10 pairs in number, as in the male of 

 L. macleayana, and the 1st pair (fig. 10) are modified in a 

 similar manner as in the latter, forming strong grasping organs. 

 The hand (fig. 11), however, is comparatively less dilated at 

 the base and of a rounded form, with 7 rather strong and 

 acute teeth along the palmar edge. Both the palmar and sub- 

 apical lobes are narrower than in the male of L. macleayana, 

 and especially the subapical lobe is far less dilated and also 

 less densely setous. 



The colour of the shell in both sexes is in alcoholic 

 specimens whitish, with a faint yellowish tinge. 



Occurrence. The specimens examined were collected 

 by Mr. Whitelegge near Sydney, together with several other 

 Entomostraca. According to Mr. Brady, the species was first 

 detected by Prof Tate, who found it in freshwater pools at 

 Rivoly Bay, South Australia. Out of the continent of Australia, 

 it has not yet been recorded.
