QUEENSLAND MOLLUSCAN NOTES, No. S. 77 
Habitat : Queensland. The type is from North-west Island, Capricorn 
Group. 
Hedley collected this species alive at Murray Island in crevices of coral 
blocks, and the operculum is thin, horny, multispiral. Specimens were compared 
in the British Museum (Natural History) and were pronounced novel. This 
beautiful species is named for Miss J. K. Allan, who has furnished so many 
excellent paintings of Australian molluscs to accompany papers by Hedley 
and myself. 
Family CEftITHIID/E. 
As noted in my last paper 1 had not solved the problems surrounding 
the generic names to be used in this family, and here offer some notes with 
regard to the names under consideration. The acceptance of the names given 
by Martyn in the Universal Conchologist has been a source of much trouble, 
and Winck worth’s conclusion, that, as Martyn was not using a binomial 
nomenclature in the explanation to the plates, Martyn’s names be rejected, is 
herewith confirmed. The beautiful figures provided by Martyn have never- 
been excelled, but his proposed system of nominating them was never published, 
and the recognition of Martyn’s temporary names has caused much confusion 
without creating any benefit. The name Clava used by Martyn in 1784 is 
therefore ignored, and we can pass on to Cerithium introduced by Bruguiere in 
1792, when a whole series of species was named but no type indicated, and 
from this point, we must determine the usage of this name. Lamarck in 1799 
cited Mure x aluco L. only, but in 1801 named Cerithium nodulosum Bruguiere 
as examples. The first type designation was made by Montfort in 1810 when 
vertagus L. was selected. Gray in 1847 included “ Cerithium Adans. Brug.,” 
with type “ Murex radula ,” but since then Cerithium has been used with 
nodulosum as example, a solution quite inacceptable. Clava was correctly 
introduced by Humphrey in the Museum Calonnianum in 1797, but Gmelin had 
used the name in a different sense in 1791, so Clava can be absolutely dismissed 
from this problem. Cerithium then seems only valid for the vertagus series, 
which have been commonly called Vertagus following Schumacher in 1817, but 
this usage was bad as Link in 1807 had pre-empted Vertagus for different 
shells. At the same time Link introduced Aluco for some cerithioid shells of 
which Cerithium adansonii was the first species, and is here named as type. 
The West African forms are not congeneric with the Pacific shells, so that 
Aluco does not come into use in Australian nomenclature. 
In 1899 Hedley described a new generic form Contumax, which later 
proved to be the very juvenile shell of nodulosum, a huge, massive, coral reef 
shell of very different appearance when adult. Yet Hod ley’s name appears to 
be the only one available for the group about nodulosum, while Pseudovertagus 
Vignal proposed for aluco can be used independently. The change from the 
juvenile to adult shown in nodulosum is somewhat paralleled in aluco, as 
described below in connection with the new species Pseudovertagus excelsior. 
The details regarding Clava can be studied in Dali. (Trans. Wagner Free Inst.
