22 SPECIES OF THE SYSTEMA. 
the description of this Zepas in the ‘Museum Ulrice.’ Lang 
furnishes a name only without figure or description appended. 
The P. cornucopia is set apart in the Linnean cabinet as an 
intended new species. 
Hepas scalpellunr. 
Gualtier, where cited, has very rudely represented the Scal- 
pellum vulgare of Darwin’s admirable Monograph of the Curri- 
pedia; Ellis more exactly the Pollicipes cornucopia of authors. 
The latter synonym has not misled naturalists, since the 
“tredecim valvi” of the description virtually excluded it. 
This erroneous reference, which is found likewise in the 
‘Fauna Suecica,’ where, indeed, the species first appeared, 
is corrected in the revised copy of the ‘Systema,’ by the 
change of the 4 into 2: the name scalpellwm, too, in the hand- 
writing of Linneus, is properly attached to the latter figure, 
on a loose engraving (Act. Angl. vol. 50, 1758, pt. 2, pl. 34) 
that formed part of his library. 
There is no reason, then, for discrediting the soundness of 
the accepted recognition (Darw. Mon. Cirri. vol. i. pl. 5, f. 15). 
Thirteen valves have usually been assigned to the species: it 
appears, however, that an additional minute rudimentary one 
may be detected on a careful examination. 
Our author has not recorded his own possession of a 
specimen. 
Hepyas anservifera. 
Our author has informed us, that this briefly charac- 
terized Cirripede looks precisely like the succeeding one, 
(which is the type of the Lepas proper), except in size and 
sculpture. Hence, as six species only are contained in the 
purified genus Lepas (Anatifa of the Lamarckian System), our 
labour of comparison is not a very toilsome one. 
It is not possible for the Lepas anserifera of modern authors, 
whose sculpture consists of incised striz, to be the species so 
named by Linneus. The raised sulci (“sulci elevati’) form
