HALIOTIS. 411 
Haltotis strtata. 
It is about as difficult to ascertain what was the Haliotis 
striata of the older writers as to discover what shell our author 
intended without examination of his collection. Martini’s 
figure (Conch. vol. i. pl. 14, f. 138) of this Har-shell, accepted as 
a correct representation of the Linnean species by Schréter, 
Dillwyn, and other writers of the older school, reminds one 
greatly of the preceding species, and seems different from both 
the one described as such by Deshayes in the ‘ Encyclopédie 
Méthodique’ (Vers, vol. ii. pt. 2, p. 180), which seems identical 
with the shell figured in plate 9, f. 3 of Humphreys’ Con- 
chology, and is perhaps the H. virginea of Reeve, and the 
‘ Haliotis delineated (vol. iii. Hal. f. 58) as striata in the ‘ Con- 
chologia Iconica’ of the last-named writer. All these three, 
however, are alike destitute of that important feature “ trans- 
versim rugosa,” for the transverse “ruge” of Linneus are, in 
this genus, at least (as we know, from his account of Midé in 
the ‘Museum Ulrice’), projecting lamellar radiating folds, and 
not merely slight wrinkles ; moreover, the spiral striz (“longitu- 
dinales secundum anfractus’’) are declared in the M. U. to be 
fine in comparison with the “ruge.’ Now the specimens 
preserved in the box marked for this species in the Linnean 
cabinet exactly fulfil these conditions, and solely of those 
present, unless, indeed, some individuals of the two preceding 
shells should be excepted, exhibit the combined sculpture. 
They seem precisely identical with the very variable Har-shell 
of Barbary and Southern Europe, the H. lamellosa of Lamarck 
(Deles. Rec. Coq. Lam. pl. 38, f. 7), and display the charac- 
teristics ascribed to striata in both the ‘Systema’ and the 
‘Museum Ulrice.’ 
Haltotis varia. 
The Haliotis varia of authors (Mart. Conch. Cab. 1. pl. 15, 
f. 144) is preserved in the box marked for this species in the
