mm., width of front 3 mm., length of merus of third leg 4.3 mm., 

 width of same 1.5 mm. 



The lateral margins of the carapace are slightly concave behind 

 the acute antero-lateral spine; the upper margin of the orbit is long 

 and sinuous; the surface is coarsely punctate, and on the anterior 

 part, single coarse bristles proceed from some of the punctse. Front 

 high, about one-fourth its width, sides parallel, lower margm most 

 produced downward at the middle. Outer postfrontal lobes scarcely 

 more than half as wide as inner ones, their anterior margin being 

 continued downward toward the lower outer angle of the front. 



Arm without subdistal spine on upper margin, but with a trian- 

 gular spine on inner margin. The outer surface of the palm has a 

 microscopic granulation and is coarsely and sparsely punctate; on 

 the upper part there are a few larger granules; the upper surface is 

 crossed by three irregular longitudmally oblique ridges subparallel 

 to the posterior margin. Inner surface of palm without transverse 

 ridge. The upper margm of the finger has a row of very small and 

 low tubercles, of which there are about 11 on the proxunal half; on 

 the distal half no tubercles are perceptible. 



Legs slender, especially in the last three segments; the merus 

 joints have no subdistal spine above, but only a right-angled tooth; 

 the dactyh are long and straight to near the end. 



Color. — The carapace in alcohol is dark, and the legs are cross- 

 banded with dark; on the propodal segments there are two dark 

 bands. 



This httle species, for the mature female is only a quarter of an 

 inch wide, has much in common with S. calypso,^ in which, however, 

 the front is wider and lower, the mcropodites of chelipeds and legs 

 have a superior spine, the meropodites of the legs are wider and the 

 dactyli more curved.
