cited figure belongs to Coronula patula, which suits not the 
expression “conica;” Klein’s is a mere copy from that one in 
Lister’s ‘ Historia,’ which is referred by Linneus himself to the 
succeeding species; Baster’s, so far as regards the shell 
portion, is wholly irrecognisable; &c., &c. A far better idea 
of the object intended was suggested by the single (erroneous) 
reference in the ‘ Fauna Suecica,’ which, by the mental addi- 
tion of the characters specified in that publication, would call 
up the image of Balanus sulcatus, a specimen of which (Wood, 
Gen. Conch. pl. 6, f. 8) is still preserved in the Linnean col- 
lection, and alone of those present answers precisely to the 
combined characteristics and locality. 
Hepas Dalawoties. 
This species was first published by our author in his ‘ Fauna 
Suecica’ with the habitat “In lapidibus vulgatissima.” ‘The 
Swedish locality, by greatly limiting the number of Lepades, 
~ with which the most comprehensively brief diagnosis must be 
compared, materially assists us in arriving at a sound con- 
clusion; the bathymetrical position of the Cirriped, ‘non 
supra refluxum, &c.,” is of no less importance, since we are 
enabled to fix upon the common littoral Balanus of Sweden 
as the representative of the Linnean species. This I conceive 
to be identical with the B. ovularis of Gould’s admirable work 
on the Invertebrata of Massachussetts (pl. 1, f. 7), which is the 
ordinary L. balanoides of British collectors —a littoral species 
with a membranous base, almost invariably confused in our 
cabinets with the calcareous-based rugosus: the latter is always 
found in deeper water, and so exactly resembles it externally 
as to render the mistake most pardonable. The “levi” of the 
brief description seems adverse to the recognition, for most 
examples are rough: it has been changed, however, to “ sub- 
striata” in the revised copy. I am assured by Darwin (the 
highest authority upon the Cirripeds) that the ovularis is not 
unfrequently smooth likewise. The synonymy throws but 
little light on the subject: Petiver merely gives us a list of 
names; Argenyille’s figure looks like B. perforatus, a Southern,
