MEMOIRS OF THE QUEENSLAND MUSEUM. 
Shell large for genus, very elevated, laterally compressed, apex excentric. 
Colour greenish white, interior green with darker lines, spatula whitish. 
Sculpture consists of strong radials crossed by weaker concentric ridges, forming 
deep pits; anterior slope steep, posterior a little less. The fasciole is filled in 
forming an elevated ridge roughened with growth stages and showing a short 
deep slit at edge; on each side of the fasciole lies a stout radial, and behind this 
some sixteen radials with a few minor intercalating ones can be seen, the whole 
crossed by about ten ridges; a faint striation can be seen with a glass of fresh 
specimens, somewhat more pronounced on the radial ribs. Length 21 mm. ; 
breadth 14 nun. ; height 16 mm. 
Habitat: North Queensland (type, Michaelmas Cay). 
Family IIALIOTIDiE. 
This family still gives concern as it proves to be more numerous in species 
and groups than has been accepted up to the last few years, and as there is 
confusion regarding the exact usage of the genus name ffaliotis I here provide 
some more names to be used for Australian species. The type of Haliotis Linne 
has been commonly regarded as the pahearctic fubercvlata , and, if so, our 
different forms need distinctive names. Montfort designated FF. asinina L. as 
type, and this needs consideration. 
The commonest species on the coral reefs is that known as varia Linne, 
a name which has been applied to a series of forms. Linne described his species 
without reference or locality, and the Philippine Island form has been 
accepted as typical. T here designate that locality as the type locality to provide 
a basis for work. T)r. Eland Shaw collected a series at Bangaan L, and these 
do not agree with Australian specimens, being larger, rounded, with less 
pronounced sculpture, &c. Associated with the small shell is a much larger 
one which is tentatively determined as jMstulifera Pilsbry (Man. Conch., xvi, 
1890, p. 96, pi. 23, f. 52). The smaller Australian shell may be subspecifieally 
named Sanhaliotis varia aliena , the genus Sanhaliotis being introduced for these 
small species, FF. varia being designated as type. A much smaller shell from 
Lord Howe Island has also been called varia , but it is very distinct and may 
be called howensis. It differs from Haliotis hanleyi Ancey in lacking the smooth 
space which is so characteristic of Ancey ’s species. This was described (Le 
Naturaliste, May 1881, p. 414) from the T. Non, New Caledonia, and as it was 
not figured lias been neglected. The type, now in the Australian Museum, is 
here figured (Plate NXXI, fig. 1) and agrees with New Caledonian shells collected 
by Mr. A. F. Basset Hull, and also with specimens from Lifu recorded as 
if. jacnensis Reeve, and also as FF. dringii Reeve, neither of which species occurs 
in New Caledonian waters. A valid New Caledonian species was described by 
Sowerby as FF. crebrisculpta (Ann Mag. Nat. Hist., ser. viii, vol. xiv, p. 478, 
pi. xix, f. 2, Dee. 1914), and this T recognised at Michaelmas Cay, North 
Queensland. 
A well-marked little species is here described as Sanhaliotis dissona sp. nov. 
(Plate XXXI, fig. 2). Shell small, elongate, spine depressed. Colour brownish 
yellow. Sculpture consists of five principal cords separated by intervals of about 
the same width, the ribs rounded, not scaly, but irregularly nodulose; smaller 
cords intercalate, and on the last whorl there are half-a-dozen subsidiary ones 
between the suture and the primary ones. Orifices depressed, oval, fairly close
