immediately posterior to maxillule, consisting of single, jflabby, 

 subcorneal projection bearing pair of setules distally. 



Female maxilliped (fig. 2g) knoblike, broad based, distally concave, 

 without armature. Male maxilliped (fig. 3a) 2-segmented, first seg- 

 ment large, strongly developed, narrow proximally, broad distally, 

 with 3 small, lappet-like projections along inner surface and single, 

 large, distally recurved projection from distal inner surface. Second 

 segment fused with clawlike terminal process, bearing single, acces- 

 sory seta proximally. 



For nature of legs and armature, see figures 2c-e, 3b-e, and table 2.

Discussion. — Pseudotaeniacanthus puhi differs from P. congeri 

 Yamaguti and Yamasu, 1959, primarily in not having the large "pos- 

 terior hooks" of the latter species, in the armatm^e of the thoracic legs, 

 and in the smaller thoracic pleura. The species name is derived 

 from "Puhi," the Hawaiian name for moray eels, the host of the 

 species.

 part of prosome, 3 free prosomal segments tapering posteriorly. 

 Small frontal region present, with rostrum. Abdomen 3- or 4-seg- 

 mented; caudal rami short. Antennule 6- or 7-segmented, proximal 

 segments not fused; antenna 3-segmented, distal segment with pecti- 

 nate margin, bearing terminal claws and setae. Mandible 2-seg- 

 mented, second segment with terminal blade and subterminal palp. 

 Postantennal process well developed, clawlike. Maxillule nodular or
