cles narrowed at middle; the corneal surface does not reach to the 

 middle of the peduncle, although it extends much farther below than 

 above and presents a very oblique inferior border. Basal article of 

 antennules dilated especially toward the base and surpassing the 

 rostrum; the two following articles very slender and of nearly equal 

 length; flagella reduced; total length of antennules nearly equal to 

 total length of carapace. Antennae extremely small, flagella very 

 slender, barely reaching extremity of second article of antennular 

 peduncles. Outer maxillipeds remarkable for length of ischium and 

 exopodite, the latter dilated, ending in front at sam.e level as the 

 ischium. 



Chelipeds well developed; palm short, swollen outside, especially 

 below; fingers a little bent inward near the base and nearly twice as 

 long as palm. Outer face of chela armed, except on fingers, with fine 

 granules forming in places curved lines. Carpus short, granulous, 

 armed inside with a spinulous lobe, and with a right angled outer line 

 but no prominent tooth. Merus triangular, bordered \nth tubercles 

 or denticles. The first ambulatory nearly surpasses the chela by the 

 entire length of its dactyl; the second surpasses the first by a similar 

 length. Last two pairs of feet very slender, reaching when straight- 

 ened nearly to the eyes; dactyls arched, two-thirds as long as propo- 

 dites.

 7.5, \\ddth 8 mm. (Milne Edwards and Bouvier.)

 than in the allied form. Wrist with a prominent blunt outer tooth or 

 spine near distal end and directed forward.
