A Neiv Rotifer, Lacinularia striolata. 33 



Whitelegge^ is quoted as describing the corona as " intermediate 

 in shape between Z. soda/is and Megalatroch.a alboflavicans." 

 This fairly describes the specimens I have seen, and after 

 examining his sketches, I have no doubt that mine are of the 

 same species as those sent to Dr. Hudson, and alluded to in 

 the description quoted. Owing to the few specimens obtained, 

 drawings of the mastax and observations of the internal structure 

 by the section method could not be attempted. The form would 

 doubtless yield interesting matter should an opportunity occur 

 to examine it further. 



Specific characters. Colony spherical, with gelatinous matrix 

 and peduncule. Female with corona three times as wide as 

 body; trochus and cingulum wide apart; mouth with contractile 

 processes running forward. Two obvious ventral antennse. Two 

 eyes. 



Dimensions. — Length of female, 1 mm. Width of body, "08 

 mm. Width of corona, '24 mm. 



Habitat. — Sydney (Mr. Whitelegge). Cultivation from dried 

 mud collected at Cheltenham. 



In concluding this paper, 1 have to thank Professor Spencer, 

 for advice and willing help in procuring books of reference for 

 me.
