placed that they fall into rows longitudinally and transversely. Two are on the middle 
line, and the others in pairs. There are five in the first transverse row, six in the next, 
two in the third, five in the fourth, and four in the last. The free edge of the telson 
carries two pairs of primary marginal spines which are pushed back into the posterior 
border. The submedians are slightly longest, acute, separated by a deep median notch, 
and with twelve long acute secondary spines on their inner and nine on their outer edge. 
The two lateral spines are also acute, and have six acute long secondary spines on their 
inner edge, and on their outer edge very numerous (twenty-four or more) long spines 
placed in two rows, one above the other, and running along the outer edge of the telson 
to its anterior end. 
The uropods are very short and small ; the paddle of the endopodite is elongated 
oval with five acute immovable spines placed in a longitudinal row on its dorsal surface, 
the paddle of the exopodite is very small, the second joint long with eight movable spines 
on its outer edge. The spines on the basal prolongation are short and acute, and the 
inner one very much shorter and more slender than the outer one.
