1898—1902. No. 18.] CRUSTACEA. 35 
end of the 1st joint of the inner, its last joint somewhat longer and 
narrower than the other 2, and armed with 3 spines and 2 geniculate 
sete; inner ramus rather slender, with each of the joints carrying inside, 
near the end, a slender curved seta, 1st joint considerably longer than 
the other 2 combined, last joint armed at the tip with a slender claw 
and a curved seta. Natatory legs rather fully developed and resembling 
in structure those in the other species of the genus. Last pair of legs 
with the distal joint very narrow, sub-linear in form and finely ciliated 
on both edges, marginal sete 5 in number and all issuing from the 
outermost part of the joint, one of them very thin, hair-like, innermost 
one the longest; inner expansion of proximal joint broadly triangular 
in form and scarcely extending to the middle of the distal joint, mar- 
ginal sete 5 in number, 2 of them attached to the inner edge. 
Length of adult female 1.05 mm. 
Remarks. — According to the structure of the posterior antenne, 
the oral parts, and the anterior pairs of legs, this form should evidently be 
referred to the genus Parameira, as defined by the present author in 
his account of the Norwegian Harpacticoida. It differs conspicuously 
from the other known species of this genus, however, in the very 
slender form of the body, the greater length of the inner ramus of the 
ist pair of legs, and finally in the shape of the last pair of legs, which 
more resembles that in the~ genus Ameiropsis, G.O.Sars. Also in 
size this form considerably exceeds any known species of the present 
genus. 
Occurrence. — Two female specimens of this form were found 
in a bottle of specimens taken on July 7, 1900, off Sjépélse Ness from a 
depth of 15—25 fathoms. 
120. Mesochra pygmea, Borck. 
This dwarf form occurred occasionally in 2 of the bottles exa- 
mined. 
Fam. Laophontide. 
121. Laophonte depressa, Scott. 
Some few specimens of this species, exactly agreeing with the form 
described by the present author from the Norwegian coast, were found 
in 2 of the bottles. Dr. Tx. Scorr records this species also from Franz 
Josef Land.
