without spines; tlie dorsal spine is somewhat longer than the ros- 
trum and about twice as long as the lateral spines. All the 4 
spines on the carapace are almost straight and are in the distal 
part furnished with setæ. The carapace is somewhat globular; at 
the forepart of the nnder-edge there is at each side a rather deep 
incision behind which 4 setæ are fixed. The eyes are very large 
and have black pigment; nowhere else is pigment to be seen. 
Antenna 1 is an unarticulated conical appendage with 5 (?) 
long setæ; but the number of these is difficult to determine as 
they most frequently lie close to one another. Antenna 2 is un- • 
articulated; the exopodite is between 3 and 4 times as long as the 
endopodite, which has 3 setæ on the tip. A little distally to the 
place where the endopodite is fixed, but on the other side, the 
exopodite has a little prominence; for the rest it is furnished 
with small setæ like those on the spines of the carapace. The la¬ 
brum has the usual form. The mandibles have no palp; the form 
of the mastigatory part may be seen from the fig.; but the 4 little 
rounded teeth are in several of the specimens not to be found. 
Maxilla 1 has no palp, but has the usual 3 lobes; the lst lobe, 
the basal lobe, is rather broad, with 6 short, ciliated setæ; the 
mastigatory lobe is longer and narrower and has 6 setæ somewhat 
longer than those of the basal lobe. Maxilla 2 has the usual form 
with a large exopodite; palp and endopodite have 2 cleft lobes. In the 
lst pair of maxillipeds the endopodite has 5 joints; it is a little 
shorter than the two-articulated exopodite that has 4 long natatory 
setæ at the tip. Also in the 2nd maxilliped the exopodite has 2 
joints and 4 natatory setæ, but the endopodite is short and has 
but 3 joints. There are no traces of the 3d maxilliped. The 
pereiopods are short unarticulated appendages; the lst pair are 
cleft. Of the pleopoda and uropoda there are no traces, and ab- 
domen has but 6 segments. On the middle of each side of 2nd 
and 3rd abdominal segment there is a spine that is large and 
curved and there are long straight lateral spines on the hind 
edges of 3rd, 4th and 5th abdominal segments. Two little
