segments. The dactylus of the raptorial claw usually bears five l teeth including the 

 apical one. 



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 5. 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 : —

1 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. 



2 I am indebted to Mr. Patience for an opportunity of examining this specimen.
