the last there is a small praelateral denticle. This denticle and each of the teeth forms 
the termination of a short but well-marked longitudinal carina. There are three 
or four (rarely two) submedian denticles, seven to nine (rarely six) intermediate and one 
lateral. The post-anal carina is well marked. 
The bifurcate process of the uropod is finely serrate internally. ‘The inner spine 
is fully twice the length of the outer and bears a small rounded external lobe near the 
distal end of its proximal half. The ultimate segment of the exopodite is almost 
equal in length to the basal segment. 
To this species I refer several extremely young individuals, between 20 and 30 
mm. in length, in which the spines at the antero-lateral angles of the carapace are not 
developed. In these examples the corneal index varies from 3°6 to 4°5, the corneal 
and peduncular axes are very slightly oblique and the median carina of the carapace is 
obsolete anteriorly. 
The general colour of living specimens of this species is usually smoky-grey. All the 
carinae of the carapace, abdomen and telson are defined by very dark grey pigment ; 
on the second abdominal somite there is frequently a dark dorsal patch and a 
similar patch is occasionally found on the fifth somite. The eyes are bright trans- 
lucent green, darker at the inner dorsal end of the cornea. The last three segments of 
the raptorial claw are pure white, those of the appendages of the last three thoracic 
somites and portions of the uropods are greenish yellow. The ventral surface is 
uniformly pale. 
The dark grey colouration mentioned above appears to persist fairly well in 
alcohol, but is sometimes entirely absent. Several specimens from Tuticorin, received 
in formalin shortly after capture, showed a wholly different type of colouring. There 
was no trace of dark pigmentation and the whole dorsal surface along with the basal 
parts of the appendages was suffused with rosy red, tending to dull purple on the 
telson and to a deep bluish purple on all the segments of the uropods except the outer 
segment of the exopod. The median and submedian carinae were red and the an- 
tennular peduncle purple.
