This was certainly an advance on Cossmann's treatment of the previous 

 year in the Essai Paleoconch. comp., vol. v, which was marred throughout 

 by a disregard of the nomenclatural laws commonly observed. Kesteven 

 had also attempted to show that all the species constituted a single genus 

 (Proc. Linn. Soc. N.S.W., vol. 27, pp. 443-83, 1902) ; but his effort was 

 prejudiced by lack of material, and consequent inability to fix relationships 

 from figures alone. I have already indicated that this group calls for a 

 competent monographer, as Dall's review was of a skeletal nature, and it 

 is difficult to reconcile the shells with the preceding synopsis. Cossmann 

 (Essai Paleoconch. comp., vol. vii, p. 232 et seq., 1906) criticized Dall's 

 classification, but his nomenclature does not agree with the facts, and his 

 rejection of the Boltenian and Linkian genera obviates much discussion of 

 his results. 



As type of Septa Perry, 1811, Dall selected Septa rubicunda Perry 

 = nodiferum Lamarck, 1822, and this was accepted, as there was no legal 

 objection possible to Dall's action. Mathews and I have, however, showed 

 that Perry, in an earlier work, named " Arcana " ("Victorian Naturalist," 

 vol. xxix, 1912, pp. 9-11), had introduced the genus-name Septa in con- 

 nection with the species S. scarlatina Perry = Murex rubecula Linne. 1758. 

 alone. This species is not congeneric with Septa rubicunda, so that Dall's 

 usage is invalidated. We observed that Pilsbry had cited Septa Perry, 

 1811, as a synonym of Aquillus Montfort, 1810; but as we now knew Septa 

 to have been published on the 1st January, 1810, it should antedate Mont- 

 fort's name, but that we did not know the date of publication of Montfort's 

 work. I have since discovered that this was reviewed in the Gotting. 

 Anzieger, as follows : Vol. i, pt. 2, p. 961, 19th June, 1809 ; vol. ii, pt. 2, 

 p. 847, 28th May, 1810. The latter date is the one concerned ; but Aquillus 

 Montfort, 1810, is an absolute synonyn of Cabestana Bolten, 1798. For 

 the Tritonis group, as Septa was unavailable, Dr. Dall (" Nautilus," vol. xxvi, 

 pp. 58-59, Sept., 1912) suggested the use of Nyctilochus Gist el, 1848. How- 

 ever, upon looking into the matter I noted that this name was not applicable,
