It is even possible that there are two series represented in the mid-Pacitio, 
as while the present species, the New Caledonian, the Vanikoro, and the 
Elizabeth Island shells, are all small and superficially similar, there is the pica 
series, cretacea-gigantea , paumotcnsis, and apparently kcrrnadcceusis, which are 
more agreeable with eaeli other in their larger size and anterior narrowing; and 
in support of this 1 find Powell describe Scutellastra tucopiana (Proc, Malae. 
Soc. (Lond.) vol. xvi, p. 169, fig. in text, 1925) from the island of Tucopia, a 
large shell measuring 92 x 75 x 25 mm. 
In Iledley ’s Queensland list there appears Acmaa cost at a Sowerby ; this 
must be expunged as 1 find the record is based upon the shell here above 
described. The southern Patel laid a alt i costal a Angas probably occurs in South 
Queensland, as other Sydney forms in this genus range that far north. I have 
recorded Patelloida petterdi Ten. -Woods from Caloundra, and now add Patelloida 
submarmorata Pilsbry, while I have collected other species belonging to this 
family at Port Douglas, North Queensland, &c., which appear to be undescribed. 
There is also another limpet living on the coastal littoral of North Queensland 
which needs study. 
Tenpetasus liberatus Pease. 
Iledley recorded Capulus ini art us Lamarck from Funafuti, Paumotus, 
Lifu, Norfolk Island, New Hebrides, and Goraldton, West Australia, and 
later in the West Australian list (Journ. Hoy. Soc. W.A., vol. i, 1915, p. 189) 
is included the same name citing Pease, Am. Journ. Conch., iii, 284, 1867, in 
confirmation. Years ago I received the species catalogued from Norfolk Island, 
and investigated its nomenclature. It was a difficult task, ms many of these 
limpet-like molluscs are superficially similar though their relationship may be 
distant. However, I found that Lamarck's species was West Indian, it probably 
had two or three earlier specific names, a generic name Krebsia Morch, and that 
it was certainly neither eonspecific nor congeneric, with the Pacific form. At 
the reference to Pease above noted, Cap-ulus liberatus was described and figured 
(pi. 24, f. 2) from the Paumotus, the date of publication being April 2, 1868. 
This name can be used at present for the shell common at Norfolk Island, and 
which I collected at Michaelmas Cay, North Queensland, the first record for 
this State. The type of Caput us is hungaricus L., whose nepionic stage consists 
of a regularly coiled smooth helicoid of one and a-half whorls succeeded by a 
varix, quite unlike the Rissoid nucleus of the Pacific liberatus , for which I 
propose the new generic name Tenpetasus. 
Iledley had listed in the Queensland catalogue two species as Capulus , 
calyptra Martyn and tricarinata L. The latter has a generic name, Amathina 
Gray (Proc. Zool, Soc. (Lond.) 1847, p. 157 ; ex Synops. Contents Brit. Mus., 
ed. 44, 63, 1842; cf. Hedale, Proc. Malae. Soc. (Lond.) vol. x, p. 302, 1913), 
and this should be used. The former has again little to do with the true Capulus, 
and it would be best to use a new genus name Capulonix for it at once. 
The .species listed as Hippo nix by Iledley need similar treatment; the 
species regarded as cornea may need description, but there is a genus Sab ia 
Gray available for conic a - ; the curious species called bar bat a Sowerby 1835 
appears to have an older name Pileopsis pilosus Deshayes (Mag. de Zool., 2 Jr., 
Class \, Moll., pi. 9, Dee. 1831), and as it is obviously not congeneric either 
with Sabia or Hipponix I here introduce a new genus Pilosabia for the Australian 
form of P. pilosus Deshayes.
