 edges ; propodos smaller and narrower than the carpus ; dactylos 

 strong, equalling the propodos in length : second pair large, with 

 a stout spine on the ischium in front ; propodos large, oval ; dac- 

 tylos small, curved, and half the length of the propodos. First 

 and second pairs of pereiopoda very small, fourth and fifth long,

 Gammarina persistently consists of five joints and the flagellum.
