tooth rectangular; a trace of a third tooth, indicated by a thickenmg 

 of the margin. 



Outer surface of merus and carpus of cheliped of female crossed by 

 short granulated rugae; merus with a short acute tooth above, no 

 large tooth but a row of denticles on the inner margin; no tooth at ■ 

 mner angle of wrist; palm relatively smooth and punctate, finely 

 rugose m the proximal and upper portions; a few obliquely longitudi- 

 nal granulated lines at the upper margin and just inside; inner margin 

 almost smooth. The lower margin of the propodus is nearly straight; 

 fingers nearly meeting, irregularly toothed; dactylus granulate at 

 the proximal end, upper margin punctate. 



Third leg about two and one-half times as long as carapace, its 

 merus over two and one-half times as long as wide; a sharp spine 

 above each merus; margms of last two segments and distal end of 

 carpal segments furry; dactyli with long horny tips, definitely shorter 

 than their respective propodi in the second and third legs, a very little 

 longer than the propodi in the first and fourth pairs. 



Near S. modestum de Man ^ and S. longipes Krauss.^ From both it 

 may be recognized by the wider front, different slope of the orbital 

 tooth, smoother hands, longer merus joints of the legs; from the 

 second by the shorter dactyli of the legs.

Type-locality.— PangSLVLTiiii River, Port. Caltom, Busuanga Island ;
