IREDALE : ON INVALID GENERIC NAMES. 175 



The four species above named will constitute the genus, the type 

 remaining as Il.falconeri (Gray). It is not without misgiving that 

 I thus transgress upon my fellow-worker's territory, but 1 have long 

 wished the opportunity of associating the name of my friend 

 Mr. Charles Hedley with some notable shell, and I do not anticipate 

 such, a splendid chance again. The genus comprises the most 

 interesting and magnificent land shells of Australia, and I sincerely 

 hope that my "imlustry will not prove abortive", to quote my 

 friend's remarks on a like occasion. 



Penion, Fischer. 



In these Proceedings (vol. x, p. 223, 1912) I advocated the usage 

 of Penion for the Austro-lS'eozelanic molluscs classed under Siphonalia, 

 and rejected the transference of Siphonalia maxima, Tryon, to 

 Megalatractus, declaring that species to be absolutely congeneric with 

 Fmus dilatatus, Quoy & Gaimard. 



Hedley in a paper on Mollusca from the Great Australian Bigkt 

 (Biol. Kec. Fishing Exp. Endeavour, vol. ii, pt. ii, p. 73, 1914) has 

 accepted my data, and has recorded Penion maximus, Tryon, and 

 P. ivaitei, Hedley. I further find that Dr. Verco in the Trans. Roy. 

 Soc. South Austr., vol. xxxvi, p. 221, 1912(1913), has gone so far as 

 to synonymize Siphonalia maxima, Tryon, with Fiisus dilatatus, Quoy 

 and Gaimard. 



It has been decided that errors of transliteration may be amended : 

 this decision, given by the International Commission on Zoological 

 Nomenclature, has the effect of causing the rejection of Penion, as 

 there is a prior Peni^cm^ (Philippi, Yerh. Zool.-botan. Gesell. Wien, 

 vol. XV, p. 741, 1865). These two names are simply the same, one 

 being wrongly transliterated, and cannot both be maintained. I have 

 therefore to propose the genus-name 



Verconella 

 to replace Penion, Fischer, and maintain the same type, Fusus dilatatus, 

 Quoy & Gaimard. The name given is an attempt to express my 

 appreciation of the work on Australian Marine Mollusca still being 

 performed by Dr. J. C. Verco. 



MoNTEOXJZiERA, Souverbic.^ 

 Hedley has recently (Rec. Austr. Mus., vol. viii, p. 135, 1912) 

 recorded the rediscovery of the interesting mollusc which Souverbie 

 (Journ. de Conch., vol. xi, p. 282, pi. xii, fig. 5, 1863) introduced as 

 generically and specifically new, under the name Montrouziera clathrata. 

 1 would point out that in honouring the brilliant Montrouzier, 

 Souverbie had been anticipated by Bigot (Ann. Soc. Ent. France, 

 3rd ser., vol. viii, p. 224, 1860), and consequently the molluscan 

 genus must be renamed. I would ask Mr. Hedley to undertake this 

 task, as to him belongs the credit of the recognition of this long-lost 

 form, and it is only fair that he should complete this item, especially 

 as I have already interfered in his province in the case of Panda.
