■carries usually two transeverse rows, the posterior row in each 

 case projecting slightly beyond the posterior margin of each 

 segment. Besides the tubercles the surface is minutely 

 granulate. 



The head is about three times as broad as long, with 

 smaller tubercles arranging themselves in four more or less 

 regular transverse rows. The anterior ridge is arcuate, 

 strongly marked, and complete. The face is slightly excavate 

 below the ridge and again deeper, providing recesses for the 

 antennae. The eyes are very small, with few ocelli — two or 

 three — which are rather separate and at the base of a small 

 tubercle. The first segment of the thorax has more than two 

 transverse rows of tubercles, but the more anterior ones are 

 irregular and more conical in shape ; the lateral margin of this 

 segment is slightly turned up, posteriorly this margin has a 

 well-defined notch, but is not grooved for any distance along 

 the margin. The epimera of the succeeding segments are 

 slightly excavated and free from tubercles below. The first 

 two segments of the abdomen are without tubercles — the second 

 has faint tubercles in some specimens — but each of the three 

 following has a single transverse row which projects behind, 

 also the terminal segment has two large tubercles, each some- 

 times obscurely divided into two, and outward from these there 

 is one on each side obscuring the margin ; the end is slightly 

 excavate. The antennules are very minute and obscurely 

 jointed. The antennae are small and short, with the two 

 jointed flagellum much shorter than the fifth peduncular joint ; 

 this is about as long as the two joints which precede it taken 

 together ; the flagellum also is much narrower than the 

 peduncle, its proximal joint being short. The labrum is well 

 defined and prominent. The mandibles are normal and rather 

 short. The legs are robust, with the joints rather sparely 

 spined, the propodi are short and tapering, the dactyli small ; 

 there are no dactylar setae. The exopods of the pleopods are 

 provided with respiratory lobes which project laterally but are 

 not much thickened. The outer rami of the uropods are very 

 minute; each terminates in a small setum. The inner rami 

 are larger, but still very short. 



Several specimens have been examined ; in some the body 

 is more ovate and the epimera more spreading ; the tubercles 

 also vary in size and definiteness. In some the antennae are 

 longer and slenderer. 



The colour varies from light-slate to brownish- white.

 laterally compressed tubercles, for the most part arranged in
