HALIOTIS. 413 
Janus of Reeve. The H. marmorata of the last-named writer 
was not published as that of preceding authors, but as of 
Gray’s MS. 
Haliotis astwina, 
The Haliotis asinina (Reeve, Conch. Icon. vol. iii. Hal. f. 18) 
of authors is present, as recorded, in the Linnean cabinet, and 
alone of its contents agrees accurately with the description in 
the ‘Systema.’ The revised copy of that publication has been 
enriched by the additional references of ‘‘ Mart. Syst. t. 16, f. 150” 
and ‘ List. 610,” which, as well as those published, were cor- 
rectly cited. 
Hattotis parba, 
Although unillustrated by any pictorial reference, the very 
peculiar feature of an externally raised canal has enabled natu- 
ralists to identify this species with certainty. For although a 
similar canal may be found in rubicundus, Emme, and less con- 
spicuously so in lauta, it cannot be said in the latter to be 
“elevatus major et evidentior illo qui foramina gerit” (M. U.), 
nor can the much-raised “foramina” of the two former be 
termed “vix prominentia” (M.U.). Hence, as the Haliotis 
parva of authors (Knorr, Dél. Yeux, pt. 1, pl. 20, f. 5) exclusively 
displays the required characteristics, no hesitation need be felt 
in accepting it as the representative of the Linnean shell. It 
has, however, received many appellations. Lamarck erroneously 
changed the name to canaliculata, notwithstanding his own 
belief that it was the parva of Linneus; Bolten has called it 
cingulata and rubicunda ; Swainson, in the ‘ Bligh Catalogue,’ 
has described it afresh as H. carinata. The absence of ex- 
amples in the Linnean cabinet is rather confirmatory than not 
of the established identification, since the species was not 
recorded to have formed part of our author’s collection.
