TL;DR: A new species of lizardfish is described based on specimens collected in the western Pacific Ocean that belongs to a species group with needle-like posterior processes of the pelvic girdle and differs from its congeners by having the following combination of characters.
Abstract: Synodus pacificus sp. nov., a new species of lizardfish, is described based on specimens collected in the western Pacific Ocean. It belongs to a species group with needle-like posterior processes of the pelvic girdle and differs from its congeners by having the following combination of characters: 4 upside-down omega-shaped marks on the lateral body; black patches on the nape and opercular region; cross bars on the ventral surface of the head; bars on the dorsal and caudal fins; orbital large (6.7–8.1% SL); interorbital space narrow (2.1–2.8% SL); snout short (6.3–7.2% SL); anterior palatine teeth not longer than posterior teeth; pectoral fin extending slightly beyond a line from base of pelvic fin to origin of dorsal fin; 7 peritoneal spots; peritoneal membrane pale; nasal flap long and pointed; dorsal-fin rays 11–13 (mainly11); anal-fin rays 9–11 (mainly 10 or 11); pectoral-fin rays 11–14 (mainly 12); total vertebrae 53 or 54; pored lateral-line scales 52–54; transverse scale rows above the lateral line 3.5, below 4.5 or 5; gill rakers 31–37; and 17–29 teeth on free end of tongue.

TL;DR: This study presents the first estimation of LWR for seven species (Blennius ocellaris, Centracanthus cirrus, E. myrus, Engraulis encrasicolus, G. niger, Synodus saurus, and Zeus faber) distributed along the northeastern Mediterranean coastal area.
Abstract: Summary
Length–weight relationships (LWR) were estimated for 31 teleost fish species caught in the Babadillimani Bight on the western entrance of Mersin Bay, Turkey. Sampling was carried out from May 1999 to April 2000 at monthly intervals using bottom trawl nets of 6 mm cod-end mesh size. The b values varied from 2.662 for Echelus myrus to 3.395 for Gobius niger, with a mean of 3.024 (±0.166). This study presents the first estimation of LWR for seven species (Blennius ocellaris, Centracanthus cirrus, E. myrus, Engraulis encrasicolus, G. niger, Synodus saurus, and Zeus faber) distributed along the northeastern Mediterranean coastal area.

TL;DR: A rare lizardfish, Synodus mundyi Randall, 2009, is newly reported from the northwestern Pacific around Japan, based on a single specimen collected from off Muko-jima island of the Ogasawara Islands at a depth of 63 m.
Abstract: A rare lizardfish, Synodus mundyi Randall, 2009, is newly reported from the northwestern Pacific around Japan, based on a single specimen (147 mm in standard length) collected from off Muko-jima island of the Ogasawara Islands at a depth of 63 m. Prior to the present study, the species was represented by only the two type specimens collected from the Hawaiian Islands. Among Japanese congeners, it is most similar to the Indo-Pacific Synodus doaki Russell and Cressey, 1979 especially in having a very long nasal flap, but differs notably from the latter in that the tip of the pectoral fin extends well beyond a line connecting the dorsaland pelvic-fin origins (vs. just reaching this level). The Japanese specimen is fully described, with a color photograph of the fresh specimen. A new standard Japanese name, “Kaede-eso”, is proposed for S. mundyi.

TL;DR: The authors restore the Synodus prima S. Patricii from the internal evidence of orthography and diction in discrete canons, in adjacent canons and in groups of canons arranged chiastically, confirmed by arithmetical features infixed in the preliminaries.
Abstract: An attempt to restore the text of the Synodus prima S. Patricii from the internal evidence of orthography and diction in discrete canons, in adjacent canons, in groups of canons arranged chiastically, the whole confirmed by arithmetical features infixed in the preliminaries.

TL;DR: Two characters not previously used for adult lizardfish identification are the form of the dermal flap of the anterior nares and the peritoneal spots, which provide an important character for identifications of larval and postlarval lizardfishes.
Abstract: Cressey, Roger. Revision of Indo-West Pacific Lizardfishes of the Genus Synodus (Pisces: Synodontidae). Smithsonian Contributions to Zoology, number 342, 53 pages, 44 figures, 4 tables, 1981.—Twenty-one species of Indo-West Pacific Synodus are described (six new species) with a key to all species: Synodus vanegatus (Lacepede) (synonyms: S. dermatogenys Fowler, S. houlti McCulloch), S. binotatus Schultz, S. capricornis Cressey and Randall, S. doaki Russell and Cressey, S. englemani Schultz, 5. fuscus Tanaka, S. gibbsi, new species (East Africa), S. hoshinonis Tanaka, S. indicus (Day) (synonym: S. dietnchi Kotthaus), S. jaculum Russell and Cressey, S. kaianus (Giinther), S. macrocephalus, new species (Indian Ocean), S. macrops Tanaka, S. oculeus, new species (Andaman Sea, South China Sea), S. randalli, new species (Red Sea), S. rubromarmoratus Russell and Cressey, S. sageneus Waite (synonyms: Xystodus banfieldi Ogilby, X. sageneus Whitley), S. similis McCulloch, S. tectus, new species (western Pacific), S. ulae Schultz, S. usitatus, new species (Hawaiian Islands, Japan). Two characters not previously used for adult lizardfish identification are the form of the dermal flap of the anterior nares and the peritoneal spots (previously described as pigment spots or abdominal spots from postlarvae). Description and numbers of these spots from all adult species provide an important character for identifications of larval and postlarval lizardfishes. Geographic variation in vertebral counts is discussed for S. vanegatus, S. binotatus, and S. englemani. Synodus similis, previously considered a synonym of S. hoshinonis by Matsubara (1938), is shown to be a valid species. Synodusjapomcus (Houttuyn) is considered a nomen dubium.
