PYCNOGONIDA -CALM AN. 
31 
Palp fairly slender, third segment three-fourths as long as second, fourth half 
as Iona; as third and shorter than fifth. 
Oviger long and slender, fourth segment two-thirds of length of fifth. 
Legs very long and slender, rather sparsely set with spinous setae, which become 
more numerous distally and only here and there exceed in length the diameter of the 
segment bearing them. Second coxa much longer than the other two together. 
Femur more than one and a half times as long as the three coxae together, at least 
sixteen times as long as its greatest diameter, with a row of about ten gland-tubercles 
on its ventral edge. Second tibia about half as long again as the first and not much 
less than twice as long as the femur. Tarsus longer by about one-third than the 
propodus, the two together measuring about one-fourth of the second tibia. Main 
claw more than half as long as propodus and three times as long as auxiliary claws.

Remarks .—This species is closely related to N. graeilipes, Miers, the characters 
and synonomy of which I have recently discussed elsewhere (19156). In view of the 
considerable range of variation shown by the forms included under that name, it is
