Segment tapered to narrow distal end, with several adhesion pads. 

 Second segment short, with proximal swelling and broad, almost 

 laminate terminal process, process with distal concavity overlying 

 knob-shaped adhesion pad on first segment when second segment 

 flexed. Male maxilliped (fig. 126) 2-segmented, also with broad base 

 extending along area of heavy sclerotization. First segment strongly 

 developed, broadest distally, with rounded, padlike process on inner 

 surface. Second segment short, heavily sclerotized, with well devel- 

 oped clawlike terminal process that overlaps 2 adhesion pads present 

 on distal anterior sm-face of first segment when second segment flexed. 

 Female and male thoracic legs I-IV biramous, with some evidence 

 of fusion exhibited, especially in female. For anlaysis of armature and 

 nature of legs, see tables 4, 5, figures 12c-/, I3a-d.

Discussion. — Pandarus cranchii and P. satyrus were synonymized 

 by Shiino (1954c). Based on the female specimens of both species in 

 the collection under description, there appears sufficient evidence to 

 warrant the maintenance of both species. This evidence includes the 

 length of the caudal rami (longer in P. cranchii), the presence of a 

 single-lobed process on antennal segment 2 of P. cranchii and a bilobed 

 process on the same segment in P. satyrus, the 1-segmented postoral 

 process of P. cranchii and the 3-segmented postoral process of P. 

 satyrus, the presence of a clump of plumosities on segment 2 of the 

 maxilla of P. cranchii and their absence on the same segment of P. 

 satyrus, the nature of the thoracic leg armature (compare tables 3
