: If Grapsus is to be entirely removed from the Brachyura, the 
name Grapsoidea cannot be retained for a Brachyurous group. 
In the group in question, Planes, Leach (Nautilograpsus, M.-E.), 
is the oldest genus; and I therefore provisionally give this group 
the name of Planide. But I also give up the name of Brachyura, 
altogether ; for Grapsus and the Dromide are Brachyura in re- 
spect.of their abdomen. I rather group together all those Deea- 
poda of which the external antenna exhibits an operculum, as 
Opercularia, and call all the remainder Tubercularia, because their 
outer antenna presents a tubercle. I consequently also get rid 
of the section Anomura, which hitherto included the forms 
which, in regard to the structure of the abdomen, constituted the 
transitions from the Macrura to the Brachyura. With respect 
to the structure of the external antenne, the Anomura agree 
throughout with the Macrura; even the Lithodide and Paguride 
exhibit more or less of the antennal scale. : 
The Opercularia consequently include all the genera cited by 
Dana as Brachyura, with the exception of the genus Grapsus in 
the restricted sense ; but, in compensation, the Bellidea, placed 
by Dana amongst the Anomura, fall into this group.

This species is of very variable aspect. Sometimes it forms 
small oval masses on the stems of Zoophytes. This is the con- 
dition figured by Mr. Busk (Catal. pl. 110. fig. 4). When de- 
veloped on the surface of shells, &c., it forms somewhat circular 
mounds, raised in the centre and sloping off towards the edge, 
Sometimes it occurs in irregularly-shaped porous masses, of very 
considerable size, involving more or less the fragment of shell or 
other body which constituted the original support of the poly-_ 
zoary. A specimen of this description from Torbay measures 
about 34 inches in length, 24 inches in width, and 1} inch in 
thickness. 
Much as this differs in general appearance from the smaller |
