Fig. 8. Branch of C. eximia, with a sac at the extremity of a stem, which 
by its position appears to have withdrawn the nutriment from an 
adjoining part, staying the growth of a shoot, which is seen as a 
short rounded lobe.

Fig. 10. Early form of parasitical young, at that period of its existence 
when it has moulted for the first time and got rid of the rudi- 
mentary legs and their appendages, being now entirely destitute 
of legs. 
Fig. 11. Further stage, or that period at which it is found free, having 
effected its escape from the sac.

Forma subovalis ; altitudo maxima ante medium sita; margo dorsalis 
valde arcuatus, ventralis im medio incurvatus. Forma desuper 
spectata ovata, in medio latissima, extremitates versus eodem modo 
parum attenuata. Latitudo altitudoque fere eequales. Basis lata, 
ad extremitates convexa, trans medium impressa atque concava. 
Valvarum superficies undique pilis obsita, cellulisque rotundatis 
numerosissimis excavata. Margo valvarum interior antice et pos- 
tice latus, lamellosus ; lamella sulco profundo excavata ; antice et 
postice aculeis fimbriatus. Co/or saturate viridis. Long. 5 unc. ;

Habitat stagna limpida prope Sedgefield in regione Dunelmensi. 
Carapace subobovate ; dorsal margin boldly arched; ventral 
margin incurved centrally ; the highest part of the valves situ- 
ated a little before the middle. Surface everywhere clothed 
with long hairs, and sculptured with closely arranged roundish 
cells. The superior portion of the anterior extremity is margined 
with a row of eight spines; and the inferior portion of the pos- 
terior extremity in the right valve is margined with about five 
spines. The lowest of these posterior spines is considerably
