inner pair much larger than the outer ; the carapace irregularly 

 granular, the granules largest just behind the frontal lobes, the 

 branchial regions rugose; the sides with two teeth behind the 

 orbital angle, the second tooth low and blunt ; the walking-legs 

 long and slender, their meropodites rugose with denticulate edges, 

 bearing at the outer end two teeth above and none below and on 

 the hinder side a low, rounded ridge, their carpopodites with two 

 sharper ridges, their propodites long and flat, their dactyl opodites 

 broad and Hat, diminishing gradually to a long straight 'spine, and 

 having the edges hidden by a thick fur ; the upper side of the 

 hand in both sexes with two subparallel denticulate ridges, the 

 inner less regular than the outer, and the two meeting at both 

 ends so as to enclose an oval field, in which two or three tubercles 

 may lie ; the fingers rather shorter than the palm in the female, 

 distinctly so in the male." 



The third maxilliped and the abdomen of the male are shown 

 in figs. 8 a and 8 b respectively. 



Length 31 mm. Breadth of fronto-orbital border 27 mm. 



The animal is described in Mr. Gardiner's notes as a " red tree- 

 crab." The colour in spirit is an orange-yellow. 



This species is not far from S. oceanica de Man, 1889, in 

 Group II. of that author's classification of the genus [Zool. Jahrb. 

 ii. Syst. 3, p. 639 (1887)], but differs in the ridges on the hand and 

 in the more hairy dactyles.
