the anterior process is acute and is much shorter and narrower than the rounded 
posterior one (fig. 48). 
Four pairs of longitudinal carinae are present on the first five abdominal somites 
and three pairs on the sixth. ‘The submedians, on all except the last somite, are 
almost lost in the coarse reticulation of the surface. There is an obscure median 
tubercle on the 2nd, 3rd, 4th and 5th somites. 
The following carinae end in spines :—

The telson is considerably longer than broad. The median carina is not notched 
at the base and terminates in a short spine which overhangs a small tubercle. On 
either side the surface is finely rugose; it bears a longitudinal line of small tubercle 
and beyond this several oblique rows of symmetrically-disposed pits leading to the 
interspaces of the intermediate denticles. These pits are very deep and often con- 
fluent so that the spaces between them are well defined and appear as blunt ridges. 
Six sharp marginal teeth are present, each of which forms the termination of a 
sharp dorsal carina. There is no praelateral denticle. ‘There are three (rarely two) 
submedian denticles, six to eight intermediate and one lateral. The post-anal crest 
is often broken up into a number of irregular tubercles. 
The bifurcate process from the base of the uropod is finely serrate internally. 
The inner spine is nearly twice the length of the outer and bears externally, at about 
its middle point, a prominent rounded lobe. The paddle or outer segment of the 
exopodite is distinctly shorter than the basal segment. 
The preserved Indian specimens of S. foveolata show no trace of their original 
colour; the Chinese examples are of a uniform blue-green tone. 
This beautifully sculptured species appears to be very rare. Nine specimens 
from the following localities are in the Indian Museum :—
