segments. The dactylus of the raptorial claw usually bears five’ teeth including the 
apical one. j 
The anterior marginal lobe of the fifth thoracic somite is rather broader at the 
base ; that of the sixth somite is truncate and the posterior lobe of the seventh somite 
is subacute and is more strongly produced than its fellow. The teeth on the margin of 
the telson are shorter and behind the lateral as in the Japanese example of S. costata 
there is a sharp and well-developed praelateral denticle; there are three submedian den- 
ticles, seven or eight (rarely nine or ten) intermediate and one lateral. The bifurcate 
process from the base of the uropods bears a small rounded lobe on the outer edge of 
the inner and longer spine. The inner edge of the process is provided with five to 
eight sharp spines. The basal segment of the uropod is only a little longer than 
the ultimate. 
The colour of well-preserved spirit specimens is characteristic. Dusky patches 
are usually visible on the dorsal surfaces of the second and fifth abdominal somites, and 
the distal end of the inner uropod and basal segment of the outer uropod are suffused with 
black. ‘The ultimate segment of the outer uropod is entirely jet-black and in this respect 
differs conspicuously from that of any other species examined (fig. 76). 
There are nine specimens in the Indian Museum :—

' Miers (1880 (a), p. 20) found seven teeth on the left-hand dactylus of a specimen from the 
Philippine Is. The additional teeth in this case were perhaps formed subsequent to an injury. 
* I am indebted to Mr. Patience for an opportunity of examining this specimen.
