This species may be considered to represent S. mantis in 

 the Indo-Pacific Region, and may be thus characterized : — The 

 rostral plate is usually oblong, smooth above, without a median 

 carina ; the lateral margin of the carapace is not angulated in 

 front of the postero-lateral lobe ; the exposed thoracic seg- 

 ments and usually two or three of the anterior postabdominal 

 segments are marked with a longitudinal median impressed 

 line. The lateral processes of the first three exposed thoracic 

 segments are bilobate ; the anterior lobe of the first segment 

 is elongated, curved forward, and acute ; in the second and 

 third segments the posterior lobe is the larger and acute. On 

 the second to sixth postabdominal segments there usually 

 exists a small median tubercle, and the first lateral carina? are 

 usually interrupted ; the upper surface of the terminal seg- 

 ment is marked with shallow pits symmetrically disposed in 

 curved lines on either side of the median keel (as in 8. mantis) ; 

 between the submedian terminal spines there are usually from 

 six to eight, and between the submedian and first lateral spines 

 usually seven or eight small denticles or spinules. The distal 

 prolongation of the base of the uropoda ends in two slender 

 elongated spines, the inner and longer of which has a small 

 tooth or lobe on its outer margin. Length of an adult male 

 about 5 1 inches.
