Body stout and strong, reaching in old males to 29 mm. 

 in length, and in females to 15 ram. Limbs rather thickly 

 furnished with spines. Second antennae from one-third to 

 two-thirds as long as the body, spreading outwards from the 

 head. Coxal plate of 2nd gnathopoda and 1st pereiopoda 

 produced on the posterior margin into a short apophysis. In 

 the males the 1st gnathopoda have no rugose processes ; the 

 2nd gnathopoda greatly dilated, the inferior margin produced 

 into a large tooth ; palm oblique, with a large triangular pro- 

 jection near the joint. Pleopoda very much reduced. 



Hah. — On sandy beaches, above high water, usually under 

 masses of old sea-weed, below which it digs its burrows. 



Locality. — This is the commonest sand-hopper in New 

 Zealand, and probably occurs on every sandy beach.
