NO. 3556 PORTUNID CRABS—-STEPHENSON AND REES 49 
males (wet), 3 males, 1 female (dried); Sta. 5181, Antonia I., eastern 
Panay, 11°36’40’N., 123°26’35”E., 26 fm., Mar. 27, 1908, Alb., 1 
Sacculina infected male; Sta. 5642, Buton Strait, 4°31’40”S., 
122°49’42”K., 37 fm., grey mud, Dec. 14, 1909, Alb., 5 males, 6 females; 
Sta. 5644, Makassar I., Buton Strait, 5°27’24”S., 122°38’00’E., 
22 fm., Dec. 16, 1909, Alb., 1 male (damaged). 
MEASUREMENTS.—Males, 16-26 mm.; females, 18-24 mm.; 
Sacculina infected male, 15 mm. 
Remarxks.—Gordon has shown that Alcock’s Neptunus spinipes 
differs from Miers’ and has listed the distinctions as well as giving 
figures of the carapaces and male pleopods of the two species. Her 
figure of the carapace of one of the cotypes differs noticeably from 
Figure 14.—Portunus spinipes (Miers), male, Philippines, Sta. 5642, Alb.: a, pleopod; 
b, pleopod tip, upper surface; c, abdomen. (Scales=a, 1 mm.; b, 0.1 mm.;c, 5 mm.) 
Miers’ figure in having a much less prominent front. The present 
specimens resemble her figure. 
The male pleopods are refigured. The species is incorrectly placed 
in the key of Stephenson and Campbell (1959) because the posterior- 
posterolateral junction of the carapace is obtuse. 
Distrisution.—Apparently only known previously from Miers’ 
material, from the Philippines, and close to Albatross Sta. 5181, 
waz 11°37'00" N.,.123°31/007E.
