from the base is the largest, the remainder tapering off to very minute proportions. 

 The eggs are small and the spherical mass is packed round the proximal part of 

 the fifth joint. 



The Legs are long and slender and attain a length of about 45mm. The second 

 leg of the right side has in this case been selected for measurement. Of the 

 coxae the first and third are sub-equal, the second being quite as long as the 

 other two together. The proportions of the three following joints are as 10 : 11 : 16, 

 and the tarsus and propodus taken together are 4'5, the former joint being a little 

 the longer of the two. A lateral line is plainly visible on the femur and to the 

 end of the leg. On the femur such setae as exist are extremely minute ; on the 

 second tibia they are very numerous but small, arranged principally dorsally and 

 ventrally, with a distinct distal fringe. On the tarsus and propodus the arrangement 

 is the same, but the setse are even more crowded. Ventrally on the propodus is a 

 row of about a dozen comparatively strong spines, more distally than proximally. 

 There is a distinct heel fringed with rather long setse. The terminal claw is stout 

 and accompanied by two auxiliaries about one-third its size. 



The Genital apertures of the male are found on the second coxse of the two 

 posterior legs, those of the female being found on all the legs. 



A number of specimens were taken in Winter Quarters in 125 fm. 



Nymphon lanare. 



(Plate III., fig. 2; Plate X., fig. 9.) 

 Specific characters : — 



Body very slender, with lateral processes long and widely separated. 

 Ocular tubercle short and stout. 



Palps five-jointed, proportions of last three 10 : 9 : 11. 



Oviger ten-jointed, denticulate spines, about double the number on the first joint as on any of 

 the others, with five to seven teeth on each side. 



Legs long and slender, with long and fine setse, terminal claw long, without auxiliaries. 



Body very slender, with lateral processes long and very widely separated. 



The Cephalon is long, expanded anteriorly into two lobes separated by a narrow 

 groove. The neck is elongated, and at its base, ventrally, are small body-processes 

 for the attachment of the ovigers, visible from the dorsal aspect. 



The Ocular tubercle is short, stout, and truncated ; it lies immediately in front, but 

 not quite clear of the first pair of lateral processes. It bears four well-developed eyes. 



The Abdomen is quite small, and does not extend as far as the posterior lateral 

 processes. It is directed slightly upwards, and not articulated to the trunk. The 

 length of the body is 8" 5mm., and its width 5mm. 



The Proboscis is cylindrical, slightly swollen in the middle, its extremity being 

 rather angular. Together with the body, it is quite devoid of setse. 



The Chelifori are well developed, long and slender. The scape is single-jointed, 

 longer than the proboscis, but scarcely as long as the chela. It bears but few setae.
