MEMOIRS OF THE QUEENSLAND MUSEUM . 
been collected previously by Iledley, but which do not appear to have been 
recorded. These are — Trochus smnhtstus Fischer (Journ. de Conchyl., 1879, 
]>. 23; id., 1886, pi. 1, f. 6: New Caledonia), placed by Pilsbry under M'molia , 
but Conotrochiis suggested, and Solar Mia I rag cm a Melvill & Standen (Journ. 
Conch., 1896, p. 313, ph xi, f. 78: Lifu, New Caledonia), under the subgenus 
Conotrochiis and generic value proposed. While the latter was placed in 
Conot radius, the former was obviously congeneric, and, as the name Conotrochiis 
is invalid through having been used by Schroeter in 1863 for a Ccelenterate 
before Pilsbry \s introduction, it is necessary to introduce a new generic name. 
The new name Vanitrochus is proposed, Melvill & Standen ? s species tragema 
being named as type. 
The species under Euchclus need redistribution as Brazier's Clanculus 
gran os ns should be transferred back to Clanculus, while Tallorhis is now 
recognised for roseola Nevill, and foveolatus A Adams is more probably a 
Herpetopoma; a new genus Vaceiichelus is introduced for Euchclus angulatus 
Pease (Amer. Journ. Conch., vol. iii, p. 283, pi. 23, f. 27, 1867) which is repre- 
sentative of a large series of Euchelus-like molluscs which lack the basal tooth to 
the columella, and more than one species occurs in Queensland as well as Pease’s 
shell. 
Family TURBINIDiE. 
The Queensland species of Turbo ( s . /.) are difficult to name, while the 
genera are as puzzling to delimit. Some genera such as those represented by 
argyrostomus , porphyrites , marmoratus, and the N.SAV. sir am, mens seem easily 
recognisable, but the names to be used are not so easily determined. The type of 
Turbo is now regarded as petholatus, and with it may be classed militaris 
(= imperial) s of TIedley’s list) and marmoratns , though the last-named appears 
at first to differ. 
Senectus can be used for the argyrostomus series, including coucinnus, 
chrysostomus , folia reus, gem mains, nivosus , spceiosus , sparverius, and tv midulus. 
Lunella will then come into use for the porphyrites series, which may be easily 
divided into three — porphyrites from New Caledonia, mespilus Gmelin (Syst. 
Nat., pi. vi, p. 3601, 1791 : Southern Ocean) from East Queensland, and porcatus 
Reeve (Conch. Icon., vol. iv., pi. xi, sp. & f. 52, March 1848) from West Australia 
and Western Queensland. 
The members of the Senectus series are. difficult to segregate and the names 
need rectification. Thus I have shown (Proc. Zool. Soc. (Bond.) 1914, p. 669) 
that Turbo foUaceus Philippi, 1846, was invalid, and must be replaced by Turbo 
squamosus Gray ( Narr. Surv. Voy. “Fly,” vol. ii, p. 359, pi. ii, fig. 8, 1847) 
described from Port Essington, Northern Territory. 
Turbo concinrms Philippi (Conch. Cab., ed. 2, p. 44, pi. 2, f. 6, 1847) is 
unavailable, and Sene etas permundus norm now is proposed to replace Philippi’s 
name. Turbo nivosus Reeve (Conch. Icon., vol. iv, pi. x, sp. 43, f. 43-44, March 
1848) from the Philippine Islands is invalidated by Montagu (Test, Brit., vol. ii, 
p. 326, 1803), and Reeve’s species is here renamed Senectus necnicosus nom, nov. 
Turbo speciosus was described by Reeve (id. ib., pi. viii, sp. 35, March 1848) 
from New Holland, sent by Bring, but the name has been used by Megerle (Verb. 
Cesell. Nat. Freunde Berlin, 214, 1824) so I name Reeve’s shell Senectus 
perspeciosus nom. nov.
