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 setae, 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 setae are abundant, particularly towards the extremity of the limb. The distal 

 fringes are normal and inconspicuous, i.e., indistinct on the first coxa, ventral or 

 chiefly so on the other two, complete on the femur ; on the two tibiae they are 

 best developed ventrally, and become spinous, especially on the second ; the tarsus 

 is covered with small spines or spinous setae 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 setae, 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 coxae 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 setae remains the same 

 it is not so clear in the young examples. In these the setae 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 setae among the others. A very few minute setae 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 chelae 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 difi'erentiated. 



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 Pfeff"er, but may be readily
