Body rather slender, reaching as much as 20 mm. in 

 length, but usually about 12 mm. Limbs with few spines. 

 Second antennae usually more than half as long as the body, 

 projecting nearly straight forward from the head. Coxal 

 plates of 2nd gnathopoda and 1st pereiopoda produced on the 

 posterior margin into an acute apophysis. In the males the 

 1st gnathopoda are spinose, and have a small rugose process on 

 the carpos and propodos ; the 2nd gnathopoda have the basos 

 narrow, the propodos narrow-oval, and the very oblique palm 

 usually bears a rounded tooth near the hinge of the dactylos. 

 The 5th pereipoda in old males often have the meros and 

 carpos dilated. Pleopoda normal. 



Eab. — Under stones, sea-weed, &c., at or below high-water 

 mark. 



Locality. — Duuedin, Moeraki, and Wellington. Probably

Body compressed, narrow-oval, about 12 mm. in length. 

 Limbs all rather spinose. Second antennae projecting straight 

 forward from the head, only about one-fourth as long as the 

 body. Coxal plates of 2nd gnathopoda and 1st pereiopoda 

 produced on the posterior margin into an apophysis. In the 

 males the 1st gnathopoda have rugose processes on the
