Genus 4. Metopina, gen. nov. 



I institute this genus to receive three aberrant forms of 

 Jifetopd, in which the first gnathopods are not subchelate, and 

 have the hand long and very .=Iender, and the terminal joint 

 very minute, flattened, not nail-formed. The second gnatho- 

 pods are very robust; the last peneopods have the posterior 

 projection of the meros well and often enormously developed. 

 The type species is Metopa pnJmata, Sars; the others are 

 M. clypeata^ Kroyer, and .1/. robusta, Sars. 



108. Metopina robusta, G. 0. Sars.
