Richard Chandler (pers com Feb 2006) who had been participating in the review of the elasmo.com paper, wrote that we had inadvertently used an erroneous reference by referring to Otodus vincenti as Winkler 1874. He had copies of the description; the date was 1878 and our page references were also incorrect (text pages 25-26, image on plate 2). Pieter De Schutter, one of the authors of the elasmo.com paper, argued he had a copy of the paper and it was 1874.

At the heart of this contradiction is a single paper printed with two dates - Deuxième Mémoire sur des dents de poissons du terrain Bruxellien. Les Héritiers Loosjes, Haarlem. This paper was printed in Archives du Musée Teyler, and evidently, released first as a short standalone paper and later as part of a set of papers.

The 1874 version describes four teeth as "Otodus Vincenti" on pages 10-11 and provides illustrations of two teeth on plate 1. (This is also the paper that describes "Odontaspis Rutoti".)

The four paper set was also printed in the Archives du Musée Teyler. In this publication, the third volume was similarly titled Deuxième Mémoire sur des dents de poissons du terrain Bruxellien. Les Héritiers Loosjes, Haarlem, but was dated 1878. These pages included the same text but were numbered 16-48 and the same illustrations were included on Plate 2.

Richard Chandler pointed out that a century ago, when synonymizing Otodus vincenti with Lamna verticalis, Leriche (1905) worded his reference as:
1874 Otodus Vincenti, Winkler. -- T.C. Winkler. Deuxième mémoire sur des dents de poissons fossiles du terrain bruxellien. Archives du Musée Teyler, vol. IV (fasc. 1, 1876), p. 25, pl. II, fig. 9, 10; Extrait, p. 10, pl., fig. 9, 10.

Richard Chandler also noted that Casier (1946) handled these references differently:

Winkler, T.C. 1873, Mémoire sur des dents de Poissons du terrain bruxellien.
	(Arch. Mus. Teyler, vol. III, fasc. IV, extraits [1873].)
- 1874a,	Mémoire sur des dents de Poissons du terrain bruxellien. (Arch. Mus. Teyler, vol. III, fasc. IV, extraits [1874].)
- 1874b,	Deuxième Mémoire sur des dents de Poissons du terrain bruxellien. (Arch. Mus. Teyler, vol. IV, fasc. I, extraits [1874].)
- 1874c.	.Mémoire sur quelques restes de Poissons du Système Heersien.. (Arch. Mus. Teyler, vol. IV, fasc. I, extraits [1874].)
- 1876b,	Deuxième Mémoire sur des dents de Poissons du terrain bruxellien. (Arch. Mus. Teyler, vol. IV, fasc. I [1876], pp. 16-48.).)
- 1878.	.Mémoire sur quelques restes de Poissons du Système Heersien.. (Arch. Mus. Teyler, vol. IV [1878].)

I'm uncertain of the rules that govern such matters, but Leriche (1905) was chronologically closer to the circumstances, possibly familiar with them and seems to have favored 1874. [Cappetta (1987) includes Palaeohypotodus rutoti as Winkler 1874]. Whether 1874 is a pre-print or 1878 is a reprint, elasmo.com will follow Leriche (1905) in this matter and use the 1874 date and following references:
Winkler, T.C., 1874a. Mémoire sur quelques restes de Poissons du Système Heersien.In: Archives du Musée Teyler, 1878; vol. IV, (fasc. 1, 1876), pp 1-15; Extraits [1874]. Les Héritiers Loosjes, Haarlem, Belgium.
Winkler, T.C., 1874b. Deuxième mémoire sur des dents de poissons fossiles du terrain bruxellien. In: Archives du Musée Teyler, 1878; vol. IV (fasc. 1, 1876), pp 16-48; Extrait, 10 pages. Les Héritiers Loosjes, Haarlem, Belgium.
