The first antenna (fig. la) conforms to the usual type, the first joint is broad, 
having a more definite wing-like expansion on its inner side than is usual, and on its 
outer border a strongly developed spine. The second joint is short, expanding 
distally. The third is much shorter still, these two together scarcely equal the first 
in length. The fourth joint is the longest and provided with a dozen tufts of 
specialised setee. Every joint bears small arborescent chromatophores. 
The second antenna is nearly half as long again as the body, and is fully clothed 
with long sete. Of the five joints of the peduncle, the first is very short, the second 
is longer, and at its ventral extremity bears a very stout spine. The proportions of 
the four joints of the peduncle and the flagellum are approximately 3. 5°5. 11. 12. 13°5. 
The three terminal joints of the peduncle are plentifully provided with long sete, 
and each joint of the flagellum bears a distal whorl of them as well as a few 
about the middle. 
The first maxilla (fig. 1b) is stout, the smaller and inner lobe has a curved outline, 
the middle of its inner margin bears a group of long sete, smaller sete are plentiful 
distally, while the extremity is armed with three stout setose spines. The outer lobe, 
which is more than doubte the size, bears numerous chromatophores, compact at the 
base but becoming arborescent distally. The middle of both inner and outer margins 
is occupied by a group ‘of short sete, and the distal extremity is armed with eight or 
nine strong but simple spines. 
The second maxilla (fig. 1c) is very broad, decorated as before with chromato- 
phores, compact at the base and arborescent distally. The inner lobe is short and 
broad, its inner margin provided with fine sete, distally it bears numerous spinous 
setee, each provided with lateral sete, but these are too short and stiff to justify 
the use of the word plumose. Of the two outer lobes, the outermost has been broken 
off in the specimen examined, the other is about one-third the diameter of the main 
lobe, and like it, it is -provided with stout sete furnished with small and stiff 
subsidiary ones. 
The maxilliped (fig. 1d). The masticatory lobe is two-jointed, and in its entirety 
has something of an hour-glass shape, being constricted at the junction of the two 
joints; the distal margin and inner angle of the second joint is fringed with stout 
plumose sete. The palp is five-jointed, stout throughout, none of the joints greatly 
exceeding the others in diameter ; the first three joints progressively increase in length, 
the fourth is as long as the third but more slender, the terminal one is a stout knob. 
All are liberally provided with setee on the inner margin, which increase in length 
to the fourth joint, and are more generally scattered over the first and second, the 
third and fourth having a distal fringe dorsally. The epignath is conical though not 
symmetrical, and the greater part of its margin is fringed with minute sete. 
The entire appendage is covered’ with black chromatophores, only a few of which are 
aborescent ; the majority are sharply-defined black spots, but many are irregular in shape. 
The first appendage of the mesosome (fig. le) is prehensile. The basis is a long
