48 T. V. HODGSON. 
these joints are subject to variation, but not of great moment, ‘5 mm. or there- 
abouts; the tarsus is quite small and cup-shaped, the propodus rather more 
than a quarter the length of the second tibia. The entire limb is covered with 
short sete, but on the second tibia and the propodus there are longer ones 
interspersed among them. Throughout the entire limb there is a broad lateral band 
devoid of setae except for a narrow row of them along its centre; dorsally and ventrally 
the sete are abundant, particularly towards the extremity of the limb. The distal 
fringes are normal and inconspicuous, 7.¢., indistinct on the first coxa, ventral or 
chiefly so on the other two, complete on the femur; on the two tibie they are 
best developed ventrally, and become spinous, especially on the second; the tarsus 
is covered with small spines or spinous sete ventrally, the propodus has a very 
prominent heel and bears a_ stout claw with two well-developed auxiliaries 
rather more than half its size. The heel bears numerous spinous sete, and at 
the proximal end of the joint on its ventral margin there are some half-dozen 
stout and prominent spines. 
The Genital apertures occur on the second coxe of all the legs in the 
female. but they can only be found on the two posterior legs of the male. 
The ova are small and numerous and are carried in a spherical packet round 
the fourth joint of the oviger. 
Several specimens of this species were taken in Winter Quarters at depths 
varying from 25 to 125 fms., the majority however coming from the latter 
depth. The specimens vary in age and size, but the species may be regarded 
as a variable one. While the general arrangement of the sete remains the same 
it is not so clear in the young examples. In these the sete are for the most 
part long and fine instead of short and comparatively stout; the transition 
from the one form to the other is gradual, some of the adults retain a goodly 
proportion of the long sete among the others. A very few minute sete may 
be found on the ‘body in some individuals, especially on the abdomen. In most 
individuals the summit of the ocular tubercle bears a very short spine instead 
of being rounded. In the young the chele are fairly well developed, they are 
of moderate size, the fingers being quite smooth and resembling a pair of callipers. 
The spur-like tubercles on the lateral processes of the adult are, in the young, 
very prominent spines and frequently bifurcated ; similar spines occur on the cephalon. 
One specimen has the oviger not completely developed and in another the full 
number of joints is not yet differentiated. 
All the adults possess a glandular aperture of some kind on the dorsal 
surface of the second coxa just beyond the middle of its length. 
One individual has the second and third legs of the left side abnormally 
developed, probably new growths in reparation of injury; one of these limbs 
does not extend beyond the extremity of the first tibia, the other is longer. 
This species very closely resembles L. clausi Pfeffer, but may be readily
