Body long and generally depressed. First pair of thoracic

 prey, the last joint folding upon the other and strongly 

 armed ; the next three pairs much smaller and generally 

 placed on the mouth, appearing to serve for holding their 

 food : they terminate in an oval hand, armed with a mov- 

 able fang; the three next pairs slender, cylindrical. Cara- 

 pace divided into three lobes; a rostral movable plate and 

 well-developed gills.
