Branchial region of Pampus echinogosfer, drawing of a cleared-and-stained preparation from a 180-mm speci men, ABE 1743. Elements identified in Figure 2. some species, of flat, bladelike spines ahead of the median fins. The genus is derived from a fish very Hke Stromateus, but with fewer vertebrae. The most primitive spe- cies in Fampus has 14 + 19 vertebrae, but the more advanced may have as many as 16 + 25. All members of the genus have the typical stromateid caudal skeleton (Fig. 47). Species. Pampus is widely distributed in tropical waters over the continental shelves from the Iranian Gulf to Japan. There are reports of specimens from Hawaii (Fowler, 1938) and from the Adriatic (Soljan, 1948). No subsequent records have appeared from either place. The two localities are so far out of the established range of the genus that the records can only have been based on specimens brought from elsewhere. Gill (1884) divided the genus Stromat- eoides {= Pampus) into tsvo groups, which he apparently regarded as subgenera. The group Stromateoides had falcate fins and prominent dorsal and anal spines; the other group, CJwndwplitcs, had neither. This dichotomy does exist in Pampus, but more work is needed to decide whether or not the distinction merits subgeneric recogni- tion. Numerous species have been described in the genus. The majority are probably synonyms. Published descriptions provide for the most part no clear-cut means of dis- tinguishing species. At the present state of knowledge, only three can be recognized: Pampus cliincnsis (Euphrasen, 1788) = Stromateus cJiinensis Euphrasen. India to China, type locality "Castellum Chinense Bocca ; D 43-50 (total elements). A 39-42 (total elements). P 24-27. Ver- tebrae 14 + 19. This species lacks the pe- culiar flat spines before the median fins which are found in the other two species
