MEMOIRS OF THE QUEENSLAND MUSEUM. 
Transtrafer longmani gen. & sp. nov. 
(Plate XXXI, figs. 10, 11.) 
Shell broadly fusiform, spire short, less than aperture, canal short, surface 
malleated. Colour' white, mouth edged with faded wine colour. Apical whorls 
one and a-half, elevated, brown, adult whorls live. Sculpture consists of 
longitudinal varicose ribs crossed by distant encircling beams which form 
square deep hollows; the shell is very thin in these hollows and translucent, 
whereas the beams are stout ; the varices are delicately edged while forming 
but do not persist save at the aperture where a series develop fine frills. 
Columella smooth, the inner lip reflected leaving an umbilical chink. Aperture 
thickened, varicose, frill-edged, internally ten teeth. Canal short, narrow, open. 
Operculum purpuroid. Length 27 mm.; breadth 18 mm. 
Collected on dead coral blocks at Michaelmas Cay. Since, Mr. Melbourne 
Ward has collected a line series in the Albany Passage, some much larger 
measuring 37 x 25 min. and having a reddish orange colour, the edges of aperture 
a deeper shade, interior white. This beautiful shell was first collected in North 
Queensland many years ago by Brazier, and then lately Iledley had found it, 
but it had not been recorded. It bears a striking resemblance to the American 
Mur ex vitulinus Lamarck, the type of Vitularia Swainson, and was placed in 
that genus in the Australian Museum collection. It is closely related to Mu, rex 
crcnifer Souverbie (Jonrn. de Conch., vol. ix, p. 279, pi. xi, figs. 9-10, July 1, 
1861), described from Balade, New Caledonia, but in the Australian shell the 
lamella are more developed, and therefore the window-like depressions much 
more pronounced. The genus should be placed next to CcraUiopkila. 
I have named the species for my friend Mr. Heber A. Longman, Director of 
the Queensland Museum, as a reminder of many favours. 
Drupina grossularia Bolten. 
Better known under the name Hist-rum digitcitu-m Lamarck, this curious 
and handsome coral-living form has not previously been recorded from Queens- 
land and Australia. Previous to the one 'secured at Michaelmas Cay, Hedlev 
had picked a. dead shell up at Bramble Cay, at the end of 1924, one of the last 
additions he made to his beloved reef mollusean fauna. 
Dali gave some Notes on Drupa and Morula (Proc. Acad. Nat. Sci. Phil., 
vol. 75, pp. 303-306, 1923) , and introduced Drupina. with type Ricimdu digitata 
Lam., and Morulma, with type R. mutim Lam., using Drupa Bolten for the type 
R. horrida Lam., and Morula Schumacher for the series R. morns Lam. Dali 
overlooked Dudley's notes in the Nautilus (vol. xxvii, p. 79, 1913) and mine 
in the Proc. Mai. Soc. (Loud), vol. xiii, p. 38, 1918. Thus he determined 
s path ulif era Blainvillc as the earliest name for the shell called hystrix by Kiener, 
and Tryon, but Iledley had already recorded rubusccesius Bolten for that species; 
he considered reeveana Crosse as only a purple-iuouthed variety of spathuUfera , 
hut Iledley had shown it was a distinct species that had been named rubusideeus 
by Bolten. He proposed the new name Morula rhifssa for R. fiscellum Reeve 
(Conch. Icon. Rieinula, pi. 4, fig. 28, 1846), but Iledley had already named that 
species Thais crassuinata ( Proc. Linn. Soc. N.S.W., xxxix, 1914, p. 749, pL lxxxv, 
f. 90, Feb. 26, 1915). Dali concluded that nodus Bory St Vincent 1816 was 
prior to morus Lamarck 1822 and papillosa Schumacher 1817. The author of 
nodus 1816 was Lamarck, not Bory St. Vincent, and I had shown that uva Bolten
