THE CRUSTACEA OK THE BERMUDA ISLANDS. 537 



First pair of antenna : basal joint of pedicel reaches beyond 

 the tip of rostrum, second and third joints together not so long 

 as the first, third a little shorter than the second ; outer flagellum 

 robust, equal in length to the pedicel, basal two-thirds fringed 

 with long cilia ; inner flagellum slender, rather more than twice 

 the length of outer. 



Second pair of antennae : scaphocerite almost as long as the 

 pedicel of the inner antennae, a spine on its distal, outer angle ; 

 flagellum a little longer than the body. 



Third pair of maxillipedes : the two terminal joints together a 

 little shorter than the antepenultimate ; distal end of penultimate 

 reaches the tip of pedicel of inner antennae. 



First pair of pereiopods : robust, shorter than the third maxil- 

 lipede, that on the left side terminates in a claw, on the right side 

 in a small chela ; the three terminal segments together equal in 

 length to the meros. Second pair of pereiopods : very slender 

 and chelate, that on the left side, when extended, reaches slightly 

 beyond third maxillipede, that on the right ride about one-third 

 longer ; a bunch of fine hairs at the base of the hand ; carpus 

 multiarticulate ; the ischium of both limbs has a sheath-like pos- 

 terior outgrowth. Third, fourth and fifth pairs of pereiopods long 

 and slender, terminating in sharp claws, each of which has a 

 bunch of fine hairs at its base and a few minute hairs near the 

 tip ; third and fifth pairs sub-equal, fourth noticeably longer, 

 principally on account of the greater relative length of the meros 

 and carpus so that the dactyl and part of the propodos reach 

 beyond the end of the third and fourth ; meros of the third pair 

 has five backwardly projecting spines. 



Telson : tapering to the apex, which terminates in a spine on 

 either side ; dorsal surface grooved, with two pairs of dorsal spines. 



Total length of a female, 14 mm., cephalo-thorax, 9 mm. 



This is the first recorded appearance of a Nika in the western 

 Atlantic. The five described species of the genus are as fol- 

 lows :
