FAMILY SPHMROMIDA. iQ)! 
what or considerably expanded, but a rim of marginal hairs 
feebly developed or wanting. Eyes at least discoverable. 
Antennulee vary as to shape and insertion, but never fitted in 
excavations on the head. Mandibles without masticatory 
process.! First thoracic legs with a robust prehensile hand 
in both sexes; second legs in the female ambulatory, in the 
male terminating in a prehensile hand differing much in 
shape or size from that of first pair. Endp. of plp.! broader 
than long. Endp. of plp.? with a few short terminal sete, 
exp. with numerous long set. LHxp. of plp.* with or without 
marginal sete; both rami of plp.o without sete. End of 
abdomen truncate or less or more triangular. Marsupial 
lamellee overlap each other very considerably (at least in 
one of the genera, Ancinella, the brood is developed in 
an enormous external pouch and in the marsupium). 
The section Campecopeini comprises two genera. 
(a) Hpistome considerably longer than broad, protruding in 
front as a rounded process visible from above. Second and 
third thoracic legs show peculiar sexual differences (see the 
notes below). Endp. of plp.' broader than long; endp. of 
plp.? nearly as broad as long; exp. of plp.® with the articula- 
tion rather near the end; endp. of plp.‘ with a few very short 
terminal sete. Urp. with both rami well developed. Marginal 
portion of abdomen visible from above. Last thoracic seg- 
ment unarmed in both sexes. (Brood in internal pouches.) 
(1) Paraspheeroma (Stebb.). 
(6) Epistome much broader than long, without any free 
frontal process, not visible from above. Second and third 
thoracic legs not showing sexual differences. ndp. of plp.! 
somewhat longer than broad ; endp. of plp.*? much longer than 
broad ; exp. of plp.? with the articulation near the middle ; 
endp. of plp.* naked at the end. Urp. with exp. elongate and 
endp. wanting. Marginal portion of the wall of abdomen bent 
not only downwards but much inwards, not visible from above. 
1 Of the genus Ancinus, (M.-Edw.). I have only examined a dried speci- 
men from the outside, but having dissected specimens of the two other genera, 
I think it allowable to draw up this diagnosis of the section.
