Twenty years later Tryon (Man. Conch., x, p. 106, pi. 35, tigs. 86, a , b) added a 
second species, crossei, reducing Leu corky nchui to subgeneric rank under 
Teiiiostoma. This was from Singapore, and from the same locality three years 
later Pilsbry added L. tryoni (Nautilus, v, p. 91, Dec. 1891). Then Melvill and 
Standen increased the number to four with a Lifu species, L. tricarinata (Journ. 
Conch. (Leeds viii, p. 311, pi. xi, f. 75, a, b, Nov. 12, 1896). Some years ago, 
I recognised Tryon ’s species from shell-sand from Shark’s Bay, West Australia, 
and now I report the two New Caledonian species from Michaelmas Cay, thus 
adding a genus as well as two species to the Queensland list, the genus being 
also first reported from Australia in this note. Four new species have been 
recently described by Thiele, 1925. 
Genus LIOTTNA. 
Under this genus name discordant species are arranged, and this oppor- 
tunity is taken to provide some better names, both generic and specific. Thus the 
species crenata Kiener typifies a peculiar series which may be called Dentareue . 
while, as it was proposed as a species of Delpliinula, the specific name is invalid 
through the prior I). crenata Sowerby (Genera Shells, pt. 39, 1833), and it is 
hero renamed Dentareue sarcim . nom. nov. Another species which may be 
classed with it is muricata Reeve, which also needs renaming as there Avas a 
/>. muricata Calcara (Mem. Conch. Altavilla, 1841, p. 75) before Reeve used it, 
so I rename Reeve’s species Dentareue man it us nom. nov. A not uncommon shell 
at Michaelmas Cay agreed with Delphi nula ci darts Reeve (Conch. Icon., vol. i, 
pi. v, sp. & f. 27, Oct. 1843: 1. Mindoro, Philippines) save that our shell is more 
rounded still, the longitudinal ribs not so pronounced, and may be given a 
subspecific name, lenullus nov., the genus name Globarene being introduced for 
it as it lias a very small umbilicus and outer lip only thickened, not variced, 
though the operculum is of the “Liotinid” style. 
Family PIIENACOLEPADIDiE. 
One of the most attractive shells on the beach of Michaelmas Cay was a 
species of Phenacolepas , and continuous searching found many specimens repre- 
senting more than one species. Three species were admitted by Iledley in his 
list, and I had found a broken piece of a fourth at Caloundra; later Sowerby 
described P. mirabilis (Proc. Malac. Soc. (Land.) ix, p. 66, fig. in text, March 
1910) which was the last-named. Simultaneously Thiele monographed the family 
in the Conch. Cabinet (Mart, and Chem.) 539e lief., Bd. ii, heft xxxiii, 1909), 
and added P. reticulata from Moreton Bay. Medley had synonymised Melvill & 
Standen ’s P. linyuamverra from Torres Straits with his P. senta from Funafuti, 
but Thiele has allowed these two as distinct, I agree with this, and moreover 
find that Medley's species had been described earlier by Gould as Copulas 
sagittifer (United States Expl. Exped., vol. xii, Moll., p. 383, pi. 32, fig. 486, a, b, 
1852: loc. unknown). 
When Iledley introduced his P. senta he pointed out that the species 
did not seem congeneric, and Thiele has also agreed that division was necessary, 
but did not perform the task. The species on the Australian ltfet were undoubtedly 
of different origin, and allowing Pkenacolepas for the species around crenulata 
Broderip, the form cinnamomea Gould is here made the type of a new genus 
Cinnalepeta . This species is a mud-dweller, and the animal has been described 
by Iledley (Proc. Linn. Soc. N.S.W., xli, 1916, p. 707. pi. xlviii, f. 17-19, April 4,
