are hinged and there are also small red chromatophores on the 

 pleura and dorsally at the distal ends of the last three segments. 

 The lateral margins of the telson and the outer edge of the external 

 uropod are deeply stained with red; on the internal uropod there 

 are scattered red chromatophores. The eggs are bright gam- 

 boge yellow. Ver}' young individuals are almost wholly trans- 

 parent. 



In specimens kept alive in an aquarium it was found that the 

 ischial and meral segments of the last three legs were held forwards, 

 downwards and a little outwards. The filiform terminal segments 

 were trailed from the distal end of the merus in much the same 

 manner as if the lash of a whip were drawn through the water from 

 the end of a stiff handle. The legs were evidently not used in 

 progression and it may be surmised that they have taken on a 

 sensory function. 



The specimens examined are from the following localities : —

In addition there are a large number of specimens, unques- 

 tionably belonging to L. ienuipes, IsiheWed " Lyttleton Harbour, 

 New Zealand; W. Guyes Brittan." I can find no reason to dis- 

 trust the label, but the record seems to require verification before 

 such a great increase in the range of the species can be accepted. 



Leander tenuipes was described by Henderson from the Gulf of 

 Martaban and Madras and has since been recorded by Nobili from 

 Bombay. It is frequently found in company with L. styliferus 

 and has occasionally been caught in surface nets near the shore. 

 Though often taken in the open sea, it is evidently far from un- 

 common in brackish water, probably migrating to estuaries and 

 up rivers at the close of the monsoon. I am not aware that it has 

 even been found in pure fresh water.
