Trachinotus carolinus ( Linnaeus 1766)

Extant specimens: MCUC ZOO.0000050 ( Fig. 28a ), and MCUC ZOO.0000067 ( Fig. 28b ).

Classification on the specimen: “P. Th. Gasterosteus ” (see comments).

Common names on the specimen (Portuguese/Tupi): Gordinha/none (see comments).

Comments: In one of the specimens (MCUC ZOO.0000067), a small rectangular piece of paper containing the name ovatus has been afixed after Gasterosteus . This suggests a subsequent reidentification of the specimen. However, in the Ichthyologia Fluminensis there is a description of G. ovatus which fits these specimens. Gasterosteus ovatus Linnaeus 1758 (= Trachinotus ovatus ) is a similar species that occurs in the Eastern Atlantic. There is a pencil inscription on the back of the herbarium sheet with a reidentification, “ Trachynotus [sic] pampanus , günther “. Trachinotus pampanus Cuvier 1832 was described long after Veloso’s death. There are 13 herborized specimens of Gasterosteus in the Ajuda’s inventory ( Ferreira 1794), but no specimen of Gasterosteus is mentioned in the transference lists to the Lisbon Academy of Sciences or the University of Coimbra. Only one of the specimens (MCUC ZOO.0000067) bears a common name, but different from most specimens of this collection, is centralized in the herbarium sheet, below the specimen itself. The Portuguese common name “gordinho” is mentioned in the Ichthyologia Fluminensis in the description of Gasterosteus ovatus . Trachinotus carolinus occurs in the Western Atlantic from Massachusetts ( USA) to Rio Grande do Sul ( Brazil) ( Menezes & Figueiredo 1980; Smith-Vaniz 2002).
