segment, distal end also with tuft of plumosities on posteromedial 

 surface. Lobate termmal process slightly less than one-fourth the 

 length of second segment, inner surface puffy and irregular, with 

 minute ridges; lateral and distal margins of process denticulated. 



Female and male maxilliped (fig. 5A) 2-segmented, situated pos- 

 terior and slightly medial to maxilla base. First segment well de- 

 veloped, with long, heavily sclerotized, lobate proximal projection 

 serving as articulation and muscle attachment surface. Inner siu-face 

 of segment with distinct, heavily sclerotized, steplike indentation 

 medially that bears single, spike-shaped protrusion^ dn anterior sur- 

 face. Distal half of inner surface irregular, with groove that re- 

 ceives terminal process of second segment when segment flexed; with 

 knob-shaped adhesion surface just anterior to groove. Second seg- 

 ment and terminal process slightly more than half the length of 

 first segment, excluding proximal projection, with slightly swollen, 

 heavily sclerotized proximal end. Second segment distinctly sepa- 

 rable from claw-shaped, heavily sclerotized terminal process in male, 

 indistinctly separable in female. 



Three pairs of thoracic legs present (figs. Qa-j) in both female and 

 male, all with greatly enlarged, plate-shaped protopodite. Protopo- 

 dite margined with minute, rod-shaped projections (not shown in 

 figures) reaching to or just breaking through cuticle. Dorsal sm*face 

 of protopodite with scattered, circular spots (not shown in figures) 

 and rod-shaped processes scattered h'regularly between spots and on 

 ventral sm-face. Fu'st and second thoracic legs of female and male 

 with distinct sinus on inner lateral surface, sinus bearing distinct 

 evidence of rami (exopodite and endopodite) in male (figs. 6d, h), 

 indistinct evidence in female (figs. &b, f). Third thoracic leg without 

 sinus and evidence of rami, in both male and female.
