Mead Abstract. — Tursiol panope Philippi, 1895 is a junior synonym of Lageno-rhynchus obscurus (Gray, 1 828) and not Cephalorhynchus eutropia (Gray, 1 846) as noted by previous authors. Rodolpho Amando Philippi (1895) men-tioned a new species of dolphin as Tursiol panope based on a skull in the Museo Na-tional de Historia Natural, Santiago, Chile (MNHN-S). He described his specimen in more detail in 1896 (p. 14, pis. 4, 5, and 6). No locality was given for the holotype but Philippi (1896: 14) implied that it was from Chile. The generic and specific identity of this delphinid have remained uncertain. True (1903:141) was unable to determine the generic affinity of T.I panope with cer-tainty, but suggested that it probably rep-resented a new genus. He based this idea on Philippi' s drawing, which showed a bowed rostrum in lateral view (Fig. 1). Trouessart (1904:766) referred to the specimen as Lis-sodelphisl panope. Harmer (1922:631) be-lieved that T.l panope might belong to the genus Cephalorhynchus. Miller (1928:171) was also uncertain about the generic affinity of the specimen but felt that it eventually would be placed in the genus Cephalorhyn-chus. He made this determination based on photographs of the type specimen taken by Waldo L. Schmitt in 1926. Unfortunately, these photographs were not published until now (Fig. 2). Cabrera (1961:615), Hersh-kovitz (1966:75), Donoso-Barros (1975:33) and Tamayo & Frassinetti (1980:364) listed T panope as a junior synonym of Cepha-lorhynchus eutropia. Sielfeld (1980:277), in his list of marine mammal specimens in Chilean museums, included a skull MNHN-S 584, under C. eutropia. This specimen was later correctly identified as the holotype of Tursiol panope by Goodall et al. (1988:203). They noted that the known range of condylobasal length (CBL) in C. eutropia is 302 to 364 mm (mean 341.3 mm, n = 13), whereas the CBL of the type of T panope was slightly greater than 379 mm (the tip of the rostrum is damaged). They left T panope as incertae sedis. All previous authors have cited Philippi, 1 896, as the type description of Tursiol pan-ope. We have used Philippi, 1895. Although Philippi (1895) provided only a synopsis of his 1 896 account of Tursiol panope and sev-eral other new small cetaceans, the descrip-tion given is valid under the International Code of Zoological Nomenclature. We be-lieve that Philippi' s 1895 work was pub-lished before Philippi (1896) because a re-print of the 1895 paper in the Museo Nacional de Historia Natural, Montevideo has a separate cover that is also dated 1895. The year of publication, therefore, should be Philippi, 1895, not Philippi, 1896. Much confusion has exited regarding the specimens, numbers, and labels of the small cetaceans in the collection at the MNHN-S. In 1986 RLB examined the type specimen of Tursiol panope and confirmed its identity as the type. Cranial damage matches that shown in the photographs taken by Waldo L. Schmitt in 1926 (see Fig. 2) and the orig-inal drawings of the type specimen (see Fig. 1). The specimen bears the (old) number 937. The catalog entry for the specimen
