MEMOIRS OF THE QUEENSLAND MUSEUM. 
and propmqua to Otopleura , and fastigium , sulcatns , feres, and monilis to 
Obeliscus. All these were described by A. Adams in the Tlies. Conch., vol. ii, as 
follows: — 
Pyramidella nitida A. Adams, Thes. Conch., ii, p. 815, pi. clxxii, f. 11: Philippines. 
Pgramidella variegata id. ib., p. 814, pi. clxxii, f. 10: I. Masbate, Philippines. 
Pyramidella propinqua id. ib., p. 814, pi. clxxii, f. 8: Keeton, Society Islands. 
Obeliscus fastigium id. ib., p. 809, pi. cdxxi, f. 8: I. Bohol, Philippines. 
Obeliscus sulcatus id. ib., p. 807, pi. elxxi, f. 34: Tahiti. 
Obeliscus teres id. ib., p. 807, pi. elxxi, f. 31-32: 1. Panay, Philippines. 
Obeliscus monilis id. ib., p. 806, pi. elxxi, f. 12: 1. Negros, Philippines. 
These determinations may need amendment when series are available, but 
the names represent different entities and there are still more. 
Dolabella auricularia Solander. 
A well-known tropical slug has a curious degenerate shell and this was 
named Patella auricularia by Solander (Cat. Portland Mus., p. 154, 1786), 
RumplPs pi. 40, f. N, being cited as representative, the locality being given as 
Amboyna. A year or more later Martyn (Univ. Conch., vol. iii, fig. 99, 1787) 
gave an excellent figure, the name selected being Patella scapula , also from 
Amboyna. Under the name Dolabella scapula it appears in both the Queensland 
and New South Wales lists, and, while the former should be now called Dolabella 
auricularia Solander, the New South Wales species is very distinct in life though 
the shell shows little differentiation. In the southern form, which grows to a 
larger size, the posterior is not so abruptly cut off, nor is the rim edged with 
branching papilla 1 , nor are these so numerous or so long on the rest of the body. 
It will be fully described and figured at a later opportunity, but in order to save 
confusion it is here named Dolabella andersoni sp. nov., the type from Gunna- 
matta, Port Hacking. 
QUEENSLAND LAND SHELLS. 
I am preparing a Synonymic List of the Land Shells of Australia, and find 
that the large Queensland shells have generally local distribution, and that 
probably more forms will be recognised than have been recently listed. It is 
important, however, to have the exact locality before deciding as to the value of 
any difference, while series are absolutely essential. The present opportunity is 
taken to introduce a fine new species which 1 name — 
Hadra mortenseni sp. nov. 
(Plate XXXI, fig. 9.) 
Shell helicoid, globose elevated, narrowly umbilieat.e. Colour of early 
whorls pale orange brown, broad bands of reddish brown developing and becoming 
deeper in colour, almost black-red just behind the aperture. On the antepenulti- 
mate whorl a subsutural line of greenish yellow is well defined, followed by a 
broad bank of dark red-brown, a narrow line of orange-red, another broader band 
of dark red-brown, a narrow line of orange-red, and then a broad presutural band 
of dark red-brown again. The last whorl shows the same colouring above the 
periphery, which is well rounded, but on the base three narrow lines of dark 
red-brown alternate with similar lines of orange, and these are succeeded by a
