MEASUREMENTS.— Males, 9-27 mm.; females, 6-21 mm.; ovig. 
females, 14-21 mm.; juv., 5 mm. 
RemarKs.—One specimen, a large male (27 mm., Pandanon I., 
Mar. 24, 1909) has the right branchial cavity swollen, presumably 
due to a parasite, and has a broader than usual abdomen. 
Crosnier has drawn attention to the remarkable variation in the 
form of the male abdomen. In the specimens he examined, the 
penultimate segment was approximately as long as broad and re- 
sembled those figured by Rathbun and Sakai; however, a penultimate 
segment much longer than broad is shown by Gordon and again by 
Stephenson and Campbell. In the present collection most of the 
specimens resemble Crosnier’s, but these intergrade to a few others 
with elongate penultimate and ultimate segments (figs. 5a-e). 
Edmondsons’ P. granulatus is discussed under P. euglyphus (Laurie). 
DistriputTion.— Madagascar and Red Sea to Hawaii, Samoa, and 
Fiji, including Japan and Australia.
