Candace truncata. 



Feminae: — Cephaloihorax posticl truncatus. Antennae anticce corporis 

 longitudine, e basi oblique projectce, deinde prope articulum sextum 

 flexce, postea recth transversa et tenuissimce ; articulo secundo crasso, 

 non longiore quam artieulus tertius quartusve. 



Female : — Cephalothorax having the posterior angles truncate. Ante- 

 rior antennae very nearly as long as the body, twenty- to twenty- 

 two-jointed, straight at base and oblique, then bent outward at an 

 angle, quite straight and very slender; second joint stout, not longer 

 than third or fourth.

In the Pacific, off Upolu, Samoan Group, February, 1841; near St. 

 Augustine Island, March 25, 1841; just south of Kingsmill Islands, 

 latitude 6° south, longitude 176° east, April 1, 1841; also, in the 

 Sooloo Archipelago, February 2, 1842. 



Length, one-twelfth of an inch. Nearly colourless ; a slight ochre- 

 ous tint, scarcely perceptible. 



The first third part of the two antennae diverge from one another 

 at an angle of about 100°; after this, both are flexed outward, and the 

 two lie in the same straight line. The joints of the basal part are 

 uneven, rather stout, and the second, third, and fourth of nearly equal 

 length. Joints at the extremity of the antennae nearly as in the pre- 

 ceding species. The maxillipeds have two very short setae on the 

 first joint. The posterior thoracic legs are quite small, with a few 

 short setae at apex. The abdomen is four-jointed, the second segment 

 much the longest, and stout gibbous below.
