spines at very unequal intervals and an apical pair, from 
between which a pair of sete project. 
The eyes are cylindrical, with small corneal surfaces which do: 
not, when turned outwards, reach beyond the breadth of the 
antennal scales, in formalin orange-coloured over dark pigment. 
In the first antennae, the peduncle just reaches end of anten- 
nal scale, first joint longer than second and third combined, 
with a broad but acutely ending spine-process little more than 
half its length. The flagella are longer than the peduncle, the 
upper outer one thickened and carrying transverse rows of 
sete for nearly three-fifths of the length, its much more slender 
and slightly shorter companion maintaining its thickness for a 
greater extent, so as subterminally to be the stouter of the two. 
In one specimen out of five this inner flagellum was much 
shorter than the other. 
The second antennae have the scale thrice as long as broad, 
the flatly-rounded apical margin not reaching beyond the 
external tooth, which is the terminal one of nineteen, fringing 
the outer margin for more than half its length. The flagellum 
is slender, about 50 mm. long. 
The mandibles have a cutting edge of five teeth, three of 
which are in a cavity between two that are much more promi- 
nent. The molar is strong, molar-like in one point of view, in 
another showing a dense tuft of setules between a strong tooth 
and a short, six-toothed blade. The slender one-jointed palp 
carries four sete. 
The first maxillae have the inner plate (lacinia media) fringed 
with slender spines, the outer plate with similar spines and also 
two rows of short spine-teeth, five in each row ; the remaining 
slender process, representing the fourth and fifths joints, carries 
two spines, of which the apical is the shorter. 
The second maxillae have a rounded lobe of the first joint 
fringed with sete, the second joint with a divided plate (lacinia 
media), both parts fringed with various spines, and the exopod 
very large, rounded at both ends and fringed with plumose 
sete, the remainder of the maxilla constituted by a short, 
narrow piece ending in three sete. 
The first maxillipeds have an epipod narrowing upwards and 
downwards, shaped like the conventional flying bird in pictures. 
The exopod is laminar for the most part, much like that of the 
second maxillae, but with a short terminal lash. 
The second maxillipeds have a long, slender exopod terminally 
sub-divided into short articulations ; the last two joints of the 
endopod strongly reflexed, the large sixth joint having its
