Additional notes on the publication of the Narrative, Zoology and Notes from a Journal of Research into the Natural History of the Voyage of H.M.S. Samarang and its consequences for the nomenclature of decapod crustaceans and other taxa.

Captain Edward Belcher was instructed by the Lords of the Admiralty to conduct a Surveying Expedition of the various coasts and islands in the Eastern Seas using H.M.S. Samarang. During this voyage from 1843-1846, Assistant-Surgeon Arthur Adams, made a significant contribution to the collection of natural history specimens, and together with fellow officers J. Richards and W. Browne, he prepared numerous drawings used by Belcher to illustrate the Narrative of the voyage. Later, Adams collaborated with Adam White (an Assistant in the Zoological Branch of the British Museum) to describe the Samarang Crustacea, published jointly with Lovell Reeve on the Samarang Mollusca, edited the Zoology of the voyage of H.M.S. Samarang and was the author of Notes from a Journal of the Natural History which was published in the Narrative of the voyage by Belcher. In his Natural History, Adams provided detailed accounts on some of the crustaceans collected with formal descriptions of species new to science thereby making these names available. The history, nomenclature and validity of the crustacean species cited in this work is discussed and a list of the available names is tabulated.

Formal recognition of the species of Oreosaurus (Reptilia, Squamata, Gymnophthalmidae) from the Sierra Nevada de Santa Marta, Colombia.

Oreosaurus is one of the two genera extracted from the former Riamasensu lato, which was recently recognized as polyphyletic. Oreosaurus is a small clade (five named and two undescribed species) of montane gymnophthalmid lizards and exhibits an exceptional distributional pattern. Its nominal and undescribed species are discontinuously distributed on the Cordillera de la Costa of Venezuela, the tepuis from the Chimantá massif in Venezuela, the highlands of the island of Trinidad, and the Sierra Nevada de Santa Marta in Colombia (SNSM). Herein, we describe the species of Oreosaurus that is endemic to the SNSM. Historically, this species associates with two names that are currently nomina nuda: Proctoporus serranus and P. specularis. Formal nomenclatural recognition of Oreosaurus serranussp. n. renders specularis a permanently unavailable name for this taxon. Oreosaurus serranussp. n. is the sister of all remaining congeners, and differs primarily from them in having only one pair of genial scales, as well as a unique pattern of scutellation. We provide an identification key to the species of Oreosaurus.

ResumenOreosaurus es uno de los dos géneros que fueron extraídos de Riamasensu lato, el cual fue reconocido recientemente como polifilético. Oreosaurus es un clado pequeño (cinco especies nominales y dos indescritas) de gimnoftálmidos de montaña y presenta un patrón de distribución excepcional. Sus especies nominales e indescritas se distribuyen discontinuamente sobre la Cordillera de la Costa de Venezuela, los tepuyes del macizo de Chimantá en Venezuela, las tierras altas de la isla de Trinidad, y la Sierra Nevada de Santa Marta en Colombia (SNSM). Describimos la especie de Oreosaurus que es endémica de la SNSM. Históricamente, esta especie se asocia con dos nombres que son nomina nuda: Proctoporus serranus y P. specularis. El reconocimiento formal de Oreosaurus serranussp. n. hace que specularis sea un nombre permanentemente indisponible para este taxón. Oreosaurus serranussp. n. es la especie hermana de todos los congéneres restantes, y se diferencia de ellos principalmente por tener un único par de escamas geneiales, así como por presentar un patrón único de escamación. Proveemos una clave de identificación para las especies de Oreosaurus.
