sty go genes

[Gr. Styx (gen it. Stygos ) = the Styx (q. v.), and gennaō =to produce. Named from their supposed volcanic abode.] Ichthy.: A genus of Hypos to matin a [SILURIDE), the preñadillas of the natives. They are small Siluroids, abundant in the lakes and torrents of the Andes, and have attracted considerable attention from the fact that Humboldt adopted the popular belief that they live in subterranean waters within the bowels of the active volcanoes in the Andes, and are ejected with streams of mud and water during eruptions, though he considered it singular that they were not cooked when vomited forth from craters or other openings. The explanation of their appearance during volcanic eruptions is that they are killed by the sulphuretted gases escaping during an eruption, and swept down by the torrents of water i uing from the volcano.
