carina is entire and ends in a sharp spine before reaching the distal margin. ‘The 
propodus has the usual three movable spines and row of pectinations along the edge 
opposed to the dactylus. ‘The dactylus bears six teeth, including the apical one, and 
the outer margin, which is obscurely angled posteriorly, is not, or is only very feebly, 
sinuous. 
There are no submedian carinae on the last four thoracic somites (fig. 21). The 
intermediates are present and on the fifth somite each is oblique and is continuous 
with the posterior margin of the single sharp spine which forms the lateral process. 
This spine points forwards and a little downwards and beneath it on the inferior 
surface of the somite there is on each side another sharp spine, which is directed 
straight downwards. ‘The lateral margins of the sixth and seventh somites are more 
or less truncate and rather sharply rounded posteriorly. 
The first five abdominal somites are remarkable for the entire absence of the sub- 
median carinae. These, however, are conspicuous on the sixth somite and the inter- 
mediates, laterals and marginals are well developed on all. The following carinae end 
in spines :—

The telson (fig. 23)' is as broad as, or a trifle broader than long. ‘The median carina 
is well marked ; it is notched near the base and ends in a sharp spine which over- 
hangs two small tubercles. On either side there is another longitudinal carina about 
three quarters the length of the median and external to these there are several other 
shorter carinae, six of which reach to the apices of the sharp primary marginal teeth. 
There are three or four submedian denticles, six to eight intermediate and one lateral. 
The praelateral denticle is present. On the ventral side of the telson the post-anal 
carina is distinct and on either side of it there are, in larger specimens, two other 
carinae which are more or less interrupted. 
The basal segment of the uropod terminates in a sharp dorsal spine which projects 
over the articulation of the exopodite. The bifurcate process bears from nine to twelve 
spines on its inner margin. The inner primary tooth is almost twice the length of the 
outer and bears a prominent external lobe at about its middle point. ‘The first 
segment of the exopodite is considerably longer than the second. 
The spirit specimens are closely covered with brownish and black chromatophores, 
which, by their absence, define an interrupted and irregular pale transverse band in 
the posterior third of the carapace. The hinder edges of the abdominal somites may 
be ‘suffused with black between the lateral and intermediate carinae. The exopodite of 
the uropod is quite black except for the anterior half of the proximal segment and the 
apices of the endopodite are similarly coloured. 
! In the Andaman specimen, from which this figure was drawn, the telson is damaged and abnormal 
on the left side.
