Etyra. eVoTrXo?, armatus, and Clytia. 



Gen, Char, Carapace fusiform, back rounded, sides convex, 

 gently compressed, posterior end slightly narrowed and deeply 



Enoploclytia, 



notched for the insertion of the abdomen, much contracted 

 anteriorly, the front extended into a long, sharp -pointed de- 

 pressed rostrum, the sides of which are armed with three or 

 four strong spines ; one strong spine over the upper external 

 angle of the orbit ; eyes on short, thick peduncles ; nuchal 

 furrow strong, slightly arched backwards, the ends reaching 

 each side margin at a point deeply notched by the abrupt nar- 

 rowing of the margin from thence to the front ; branchial fur- 

 rows double, inclosing between them a narrow, pointed ridge on 

 each side, which meets its opposite fellow at less than a right 

 angle (each meets the midline of the back at an angle of about 

 40°) on a point of the back about halfway between the nuchal 

 furrow and the posterior margin ; abdomen (including the tail- 

 fins) shorter than the carapace, segments very weak, slightly 

 arched, their ends triangularly pointed (ends of the second one 

 not dilated), sixth longer than the preceding ones, giving origin 

 to the two broad, rotundato-trigonal pair of side-flaps of the tail, 

 which are very large, thin, and undivided by transverse sutures ; 

 seventh segment (or middle tail-flap) subtrigonal, thicker than 

 the others and tuberculated ; surface of carapace, legs and 

 chelae covered with large spinose tubercles and intervening 

 granules of very irregular size ; fii^st pair of feet or chelae very 

 large, subcompressed, fingers slender, with a row of large 

 teeth on the inner edge, carpus very short, tumid, trigonal ; 

 three next pair of legs slender, compressed (? apparently ter- 

 minated by a blunt, trigonal, simple claw) ; fifh pair not 



seen.
