ItemA fourth Neotropical species of synbranchid eel and the phylogeny and systematics of synbranchiform fishes. Bulletin of the AMNH ; v. 157, article 1(New York : American Museum of Natural History, 1976) Rosen, Donn Eric, 1929-; Greenwood, Peter Humphry."The discovery of an undescribed species of synbranchiform eel, with populations in the Atlantic slope of Mexico, Guatemala, Honduras, Cuba, and northeastern South America, presented problems in its taxonomic assignment that required a review of the genera and higher groups within the order. Analyses of superficial anatomy, skull, and vertebral column, but particularly of the detailed structure of the hyoid, gill arch, and branchial vascular systems indicated that some of the groups of synbranchiform species are paraphyletic and others polyphyletic, and that the Alabetidae, long associated with the swamp eels, should be excluded from the assemblage. A phylogenetic hypothesis is put forward that divides all synbranchiforms (treated here as the single family Synbranchidae) into two lineages: the Macrotreminae (containing only Macrotrema caligans) and the Synbranchinae (including three genera: Ophisternon (containing the species bengalense, gutturale, candidum, afrum, infernale, and the new neotropical form aenigmaticum), Synbranchus (containing marmoratus and madeirae), Monopterus (containing albus, boueti, cuchia, fossorius, and two forms originally described under the name indicus)). The generic names Furmastix and Anomatophasma are placed in the synonymy of Ophisternon, and Typhlosynbranchus and Amphipnous are placed in the synonymy of Monopterus. The nomenclatural histories of the genera and some species are discussed and an analytical key to the subfamilies, genera, and species is provided"--P. 5. ItemNotes on the structure and relationships of the alepocephaloid fishes. American Museum novitates ; no. 2473(New York, N.Y. : American Museum of Natural History, 1971) Greenwood, Peter Humphry.; Rosen, Donn Eric, 1929-"The alepocephaloid fishes, which have had a long, uncertain taxonomic history, are compared with members of the Argentinoidei. The two groups share a distinctive pharyngobranchial structure not known to occur in any other major group of fishes. Study of the caudal skeleton of alepocephaloids and argentinoids reveals additional trenchant similarities between these two groups. Other anatomical information is consistent with the hypothesis that alepocephaloids and argentinoids form a monophyletic assemblage. The two groups are included as two superfamilies, the Alepocephaloidea and Argentinoidea, of the suborder Argentinoidei. Suggested rearrangements of members of the Argentinoidea also are propsed"--P. . ItemOrigin of the Weberian apparatus and the relationships of the ostariophysan and gonorynchiform fishes. American Museum novitates ; no. 2428(New York, N.Y. : American Museum of Natural History, 1970) Rosen, Donn Eric, 1929-; Greenwood, Peter Humphry.; Anderson, Sydney, 1927-; Weitzman, Stanley H.; American Museum-Bolivian Expeditions (1963-1965) ItemPhyletic studies of teleostean fishes, with a provisional classification of living forms. Bulletin of the AMNH ; v. 131, article 4(New York : [American Museum of Natural History], 1966) Greenwood, Peter Humphry.; Rosen, Donn Eric, 1929-; Weitzman, Stanley H.; Myers, George S. (George Sprague), 1905-1985.
