NO. 3574 COPEPOD CRUSTACEANS — LEWIS 185 



distally, without armature. Endopodite 2-segmented, slightly more 

 than one-third the length of protopodite. First segment approxi- 

 mately twice the length of second, with small, finely denticulated 

 knob on inner surface. Distal surface of second segment flattened, 

 with 2 small spinules on inner half and single, larger spinule on outer 

 half. 



Mandible (fig. 69e) appearing 3-parted, rodlike; distalmost part 

 flattened, inner surface with 9 denticidations, the third slightly smaller 

 and considered a secondary denticulation by Kabata (from correspond- 

 ence) . Maxillule (fig. 69/) ad j acent to posterior lateral portion of mouth 

 cone base, consisting of stalk bearing single palp on median posterior 

 surface, palp with 2 terminal spinules; 2 elongate, spinule-tipped 

 dactyliform processes present on distal end of maxillule. MaxUla 

 (fig. 69^) prehensile, 2-segmented, situated well posterior to mouth 

 cone base. First segment strongly developed, proximal and outer 

 margins flatly convex, inner surface indented medially, indentation 

 with pocket-like depression receiving terminal process of second 

 segment when segment flexed. Second segment short, heavily scle- 

 rotized, fused with clawlike terminal process, and bearing minute, 

 spinelike accessory process on inner surface. 



Maxilliped (fig. Q9h) 2-segmented, originating from irregular pro- 

 jection immediately posterior to maxillae. First segment strongly 

 developed, narrow proximally, flared to broad distal half; inner surface 

 indented distally, indentation with small concavity receiving terminal 

 process of second segment when segment flexed. Second segment 

 smaU, heavily sclerotized, fused with clawlike terminal process, 

 bearing small, spinelike accessory process from inner surface and 

 minute, spinule-like process from outer surface. 



Discussion. — The species is placed in the genus Brachiella be- 

 cause the female cephalothorax is elongate and cylindrical, is flexed 

 backward, and is "covered" by a heavily sclerotized tergum. Addi- 

 tionally, the trunk of the female is swollen and flattened dorsoven- 

 trally, there are 4 pau's of posterior processes, an unpau'ed genital 

 process is present, and there is no visible abdomen or caudal rami. 

 The characteristics of the male cast some doubt on the inclusion of 

 the species in Brachiella. The prosome and urosome of the figured 

 specimen are in an essentially straight line although the urosome of 

 the second male specimen is at an angle to the prosome. The author 

 is deeply indebted to Dr. Z. Kabata for a rather exhaustive examina- 

 tion of the paratype material and a comparison of the male with the 

 male of Andropoda lampri (Scott, 1901). Based upon the comparison 

 of the males of B. regia and A. lampri and upon the similarity of the 

 female of B. regia with other members of the genus Brachiella, the 

 species is presently placed within this genus.
