Abstract

Fragments of the large euryptcrid Pterygotus, recently collected from the Devonian Campbellton Formation at Atholville, New Brunswick, are identified as belonging to P. anglicus Agassiz. The only previous Pterygotus specimens from this site, collected in 1881, were assigned to a new species P. atlanticus Clarke and Ruedemann, in 1912. Clarke and Ruedcmann's suggestion that P. atlanticus might turn out to be a small specimen of P. anglicus is supported by this new find. However, possible revision of P. atlanticus awaits the discovery of additional, more complete, material. RÉSUMÉ On a déterminé que les fragments du grand euryptéride Pterygotus récemment recueillis dans la Formation dévonienne de Campbellton à Atholville, Nouveau-Brunswick, appartenaient au P, anglicus Agassiz. Les seuls spécimens antérieurs de Pterygotus de cet emplacement, préIevés en 1881, avaient été attribués à une nouvelle espèce, le P. atlanticus, par Clarke et Ruedemann, en 1912. Cette nouvelle découverte appuie l’hypothese de Clarke et Ruedemann à l'effet que Ie P. atlanticus pourrait en réalité constituer un petit spécimen de P. anglicus. La révision possible de la nature du P. atlanticus nécessitera néanmoins la découverte de matériel supplémentaire plus complet. [Traduit par la rédaction]
