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 then- 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.
