82. I^EKiTA (Thelicostyla) oryzarum, Recluz. 

 Obtained in the estuary of the Canton River. 



83. Nekita chameleon, Linn. 



A few specimens not exactly typical -were obtained at Shawei Shan 

 Island, at the mouth of the Yangtze Kiang. 



84. Nerita albicilla, Linn, 



A few specimens were obtained at Labuan. 



85. Neritina. 



Of Neritina four species were obtained, and of these three were 

 observed in the neighbourhood of Hong Kong and one at Labuan. 



Of those at Hong Kong, Neritina variegata, Rve., lives always in 

 clear, rapidly running, rocky streams, and is generally distributed on the 

 mainland adjoining Hong Kong. N. (Clitho7i) meleagris, Lamk., was 

 only found in one very limited area, in a deep pool at a spot where 

 a small mountain stream debouched into the sea ; and N. puUhella, Rve., 

 like N. variegata, is most widely distributed about Hong Kong, but, 

 unlike it, never appears to venture above high- water mark, so that 

 practically it lives, all its life, among the sea-washed pebbles of 

 the shore. 



One specimen of Neritina crepididaria, Lamk., was taken in a man- 

 grove swamp at Labuan. 



86. Neritopsis radula (Linn.). 

 A few specimens at Labuan.
