adult g¢, but the lower part of hind margin is straight, the teeth are 
as in the young ¢, but sharper and more closely set. 
Fifth peraeopod, hind margin of 2nd joint strongly convex, serrate. 
Seventh joint of all the peraeopods with 2-3 spine-setae at inner apex. 
Third uropods as figured for serrula. 
Length: 6 9mm.; 9 6mm. 
Colour: White, with a somewhat irregularly reticulated transverse 
violet band on the head and each of the peraeon and pleon segments, 
in the median line on the peraeon and pleon there is a lozenge-shaped 
patch of the white ground colour surrounded by a border of violet, at 
the hinder end of which is a deep violet spot, side-plates and 2nd 
joints of 3rd to 5th peraeopods with a broad violet stripe, antennae 
ringed with violet, eyes black.

Haswell’s description is very brief, and his figure of the 2nd gnatho- 
pod is not at all clear, so that it is very doubtful if the present speci- 
men is correctly assigned to his species. Moreover, it is thrice as long 
as the original one, which was most probably immature. 
Eyes elongate oval, vertical. Peraeon and pleon without serrations 
or setae. Side-plate 1 fairly produced forwards, inferior margins of 
1-4 not serrate, 5 not as deep as 4. Postero-inferior angle of 3rd 
pleon segment quadrate with a very minute point, posterior margin 
straight, entire. 
Telson cleft for 2 of its length, lobes dehiscent, apices excavate 
between two teeth, a small tooth at base of excavation, whence arise 
also 2 unequal stout spines. 
First antenna reaching to end of peraeon, 2nd joint a little longer 
than Ist, 3rd 4 2nd, flagellum shorter than peduncle, ca. 25-jointed, 
accessory flagellum 4-jointed, equal to the first 4-5 flagellar joints.
