Size much larger than that of the typical species, the male 

 16,5 m.m. long, the feinale 18,5 m.ra. Stylocerite just exceeding 

 Ist antennular article, scale of scaphocerite extending to the ex- 

 treniity of antennular peduucle. Frontal margin at either side of 

 the rostrum straight, transverse. 



Large chela of adult male a little higher, proportion between 

 the whole length and height of palm 2,65. Triangular groove on 

 the inner side of the palm as deep and as well developed as that 

 on the outer side, the lower border of that groove slightly 

 sinuous, not coloured, the groove somewhat hairy; both grooves 

 reach farther downward thau in the typical species. In the female 

 and in younger specimens this chela is almost or just 3-times 

 longer than high. 



Smaller chela 4-times as long as high, both in the male and 

 in the female. In the male the fingers are a little shorter than the 

 palm, upper border of the palm distinctly notched, both the 

 outer and the inner groove wel] developed, lower border a little 

 sinuous; dactylus Balaeiiiceps-shaTped. In the female the fingers 

 are slightly longer than the palm, the latter without grooves or 

 notches, dactylus simple. 



Second segment of carpus of 2nd legs a little shorter than 

 Ist, the segments presenting a rather not slender form, the 3rd 

 e. g. 1,65 — 1,85-times as long as thick. Meropodite of 3rd legs 

 5, 4-times longer than wide, distal extremity of lower margin 

 obtuse; propodite 1,35-times as long as the carpus, dactylus al- 

 most half as long as the propodite.
