FAMILY SPHAROMIDA. 107 
behind the other”’ ; the end of the posterior one, situated con- 
siderably above and a little beyond the end of abdomen, bears 
the respiratory circular foramen which is connected with the 
end by a long linear slit ; urp. has exp. in both sexes styliform, 
narrowing towards the acute end, in the male more than twice 
as long as endp., curved, in the sub-adult female a little longer 
than endp., straight.! 
(2) Nzsicopea (Stebb.). 
($$$) Both sexes rather similar in aspect, without real pro- 
cesses ; abdomen with a notch which is semicircular or oblong 
in the female, in the male narrow in the distal part, while 
the proximai part constitutes a transverse foramen ; urp. sub- 
similar in both sexes, with the rami lamellar. Mouth-parts 
similar in both sexes; male with appendix masculina on 
endp. of plp.?; marsupial lamellae overlap each other some- 
what, but the propagation is unknown. 
(3) Dynamenella (n. gen.). 
($$$$) Both sexes similar, without processes. Distal part of 
abdomen somewhat produced, with the lateral walls bent 
strongly downwards and inwards, constituting a rather long 
tube open at both ends and with a slit on the lower surface ; 
urp. similar in both sexes, rami lamellar, exp. considerably 
shorter than endp. Mouth-parts similar in both sexes; male 
with appendix masculina on endp. of plp.*; marsupial lamelle 
overlap each other somewhat; the brood in an exceedingly 
large external pouch and in the marsupium. 
(4) Cymodocella (Pfeff.). 
(tt) Urp. without exp., but endp. large, lamellar. Both 
sexes similar, without processes; end of abdomen with a 
semi-circular notch. Mouth-parts similar in both sexes; 
marsupial lamella overlap each other considerably, and the 
brood is developed in internal pouches. 
(5) Scutuloidea (Chilt.), 
1 The diagnosis is deficient, because mouth-parts and pleopods had been 
removed before my examination from the two specimens hitherto known, a 
female with rudimentary marsupial lamellz and a male.
