LEPAS. 23 
a remarkable feature, and one that is solely to be found in 
L. pectinata (Wood, Gen. Conch. pl. 12, f. 1, as suleata), which 
must consequently have been the species originally intended. 
This conclusion had been arrived at by Poli, who appears to 
have conscientiously studied the text of the ‘Systema.’ The 
circumstance that Linneus had referred Lister’s characteristic 
figure (Conch. t. 440, f. 283) of the spurious anserifera to 
anatifera was sufficient to rouse suspicion: very few writers, 
however, have critically analysed the synonymy of our author. 
Lepas anattfera. 
So minute, however essential, are the differences between 
those closely allied Lepades, the anatifera, Hillii, and Australis 
of Darwin’s Monograph, that to boldly pronounce to which of 
the three each of the synonyms appended to this barnacle 
should be attributed would be sheer presumption: the rude- 
ness of the figures and inadequacy of the descriptions afford 
too wide a field for conjecture. The two former, indeed, were 
certainly confused in both the cabinet of Linnzeus (where they 
solely answer to the definition) and in his references; at least, 
I take Ellis, (not “Hil.” as misprinted), fig. 6, and Seba, 
fig. 2, by the distance of the carina from the scutum, for 
L. Hillit, whilst many of the other drawings bear a stronger 
likeness to L. anatifera. Under such circumstances, where no 
veritable discriminative features are indicated by an author, it 
is ever expedient that the dictum of that writer who has first 
appreciated the essential distinctions should be followed: 
moreover, the expression “acutis,” applied to the scuta in the 
‘Museum Ulrice,’ is not so strictly applicable to Hillw as to its 
congener. Hence the Lepas anatifera of Darwin (Mon. Curr. 
vol. i. pl. 1, f. 1) seems best entitled to the Linnean appel- 
lation. : 
In the revised copy, the reference to Lister’s ‘ Historia’ is 
changed from “ 440” (generally quoted for anserifera) to “ 439, 
f. 282,” the var. dentata of anatifera. 
The references in the ‘Museum Ulvice’ actually include a 
Scalpellum (Arg. pl. 30, f. G, and Gualt. pl. 106, f. C)! well
