Powell. — Description of a new C'rustacean. 295 



distally, the carpus produced to nearly half the length of the propodos postero- 

 distally, the anterior edge serrated, terminating in a sharp point. 



Second pair of gnathopoda have the meros produced postero-distally into a 

 long narrow process, nearly half the length of the carpus; the carpus has a 

 similarly situated long narrow process, more than half the length of the 

 propodos. 



Third pair of pereiopoda Lave the base produced postero-distally into a 

 sharp point not quite at the termination of the basos and springing off at a 

 rather obtuse angle, the ischia produced antero-distally into a small sharp 

 tooth; the carpus antero-distally produced to two-thirds the length of the 

 propodos, provided with a prominent tooth at the centre of its inner margin; 

 propodos long and slender, falcate, and furnished with an obtuse tubercle, 

 corresponding to the proximal aspect of the carpal tooth. 



The whole animal perfectly pellucid with the exception of the eyes which 



have a red colour. 



Diagnostic points. — The long sharp process on the niera of the second pair 

 of gnathopoda, the processes on the basa and ischia of the third pair of 

 pereiopoda. Whether these characters are of sufficient importance to raise 

 P. novce-zealandice to the dignity of a species I am not sure, but they at all

species as P. custos, P. bornerasis, and P. atlantica.

North Canterbury. By the Rev. J. W. Stack. 



[Read before the Philosophical Institute of Canterbury ', 7th May, 1874.] 



The absence of living specimens, coupled with the absence of all traces of 

 recent remains, would render the task of proving that the large lizards existed 

 till quite lately in this part of the country very difficult but for the fact that 

 f,Wfl are manv Maoris still living who have not only seen but handled and
