occurs between the 5th and 6th jomts. A long filament 
springs from the 4th joint. Posterior antenne (fig. 5) two 
jointed, the inner branch being composed of one joint 
with three terminal sete. 
Hand and claw of the second foot jaw slender. First 
joint of the inner branch of first pair of swimming feet 
(fig. 7) about the same length as the entire outer branch, 
the middle joint has two small sete on the inner side; 
the outer side of the outer joint is ciliated. Both branches 
of the second, third and fourth feet (fig. 8) are three jointed. 
The basal joint of the fifth pair of female (fig. 9) is triangular 
bearing three terminal setze : the second joint is long, shehtly 
oval, ciliated at each side and bearing four sete. The 
fifth feet of the male (fig. 10) are very similar to those of 
the female but are rather smaller, and not ciliated and 
have fewer sete. The abdomen of the female is five 
jointed, in the male four jointed. Caudal seements about 
four times as long as broad and slightly tapering, termin- 
ated by two long and several short sete. 
Several specimens of this species nearly all females were 
lately found in mud dredged from seven fathoms inside 
Port Erin breakwater. Their extreme minuteness and 
delicacy render dissection difficult and the mouth organs 
I have not been able to make out clearly. 
Jonesiella fusiformis, Brady & Rob. (PI. XIX, fig. 8.) 
Length 1.25 mm. Dredged off the Calf of Man in 20 
fathoms and off Puffin Island. 
Jonestella hyene, Thompson, (Pl. XX, fig. 1.) 
Length 0.65mm. First dredged from steamer ‘‘Hyeena,”’ 
in Port Erin Bay, and since found there in considerable 
number on a muddy bottom. It is described in Appendix 
to 3rd Report on the Copepoda of Liverpool Bay. Proc. 
L’pool Biol. Soc., 1888-9, Vol. III, p. 192.
