EXPLANATION OF PLATE CIV. 
Fig. 1. From a drawing taken * from the woodcut in Chapter xxvi. of 
Sir John Maundevile’s Voiage.” This should he compared 
with the woodcut t at p. 388, borrowed by Prof. Max Muller 
from Gerarde’s Herball,” 
„ 2. Taken from fig. 3 of a plate in the ^^Phil. Trans.,” accom- 
panying Sir Robert Moray’s Relation concerning Barnacles.’ 
This seems to supply a link between the mythical epoch, as 
represented by Gerarde’s figure, and that of fact, as repre- 
sented by the following diagram. 
„ 3. Diagram of the capitulum of a Lepas, showing the relations of 
the various factors of the shell, reduced and modified — e.g. 
by turning it upside down, for better comparison with fig. 2 
— from Darwin’s figure (fig. 1) at p. 3 of his Monograph on 
Lepadidce. (c) Carina. J (f) Tergum. (set) Scutum.

„ 4. Drawn by the author from a specimen belonging to the Uni- 
versity Museum, Oxford. The bottle containing it is thus 
labelled : — Conchoderma Hunteri, on carapace of a crab 
from Amoy. The eye is situated in this species on the oral 
side of the adductor, the reverse of its position in LepasP 
On the right side, three of the Cirripedes are in situ, while, 
on the left, only one out of two originally adherent remains, 
the position of its former neighbour being indicated by a 
scar-like pit in the carapace of the crab. 
„ 5, 6. Modified from woodcuts in Darwin’s ‘‘ Monograph of the Cirri- 
pedia,” illustrating the homologies between this group as 
represented by a Lepas (fig. 6), and the Crustacea, as repre- 
sented by one of the Stomapoda (fig. 5). Those somites ” 
of the Crustacean body, which are present in the Cirripede, 
are coloured dark, those being merely left in outline which 
have no representative in the latter group. (^) Peduncle,

„ 7, 8, 9. Reduced and modified from figures in Tafs. viii. ix. of Prof. 
Hackel’s ^^Natiirliche Schopfungsgeschichte.” Fig. 7 is the 
larval form (Nauplius) of a Lepas, such as may be conve- 
niently represented by the preceding figure, while figs. 8, 9 
respectively illustrate the Nauplius and adult stage of a
