IV. On the early development of Lepidosteus osseus . — Preliminary notice

Abstract

In the spring of 1888 I journeyed to North America for the purpose of collecting material for a study of Ganoid development. I sought and found even more material than I wanted in the now well-known habitat of Lepidosteus , Black Lake, N. Y. No better hunting-ground could be wished for by the morphologist in search of Ganoid material. The lake contains Amia , multitudes of Lepidosteus , and (it is said) sturgeons. One need not be at much trouble in seeking sturgeons, for the River St. Lawrence, which flows within 12 miles of Black Lake, will vie with any Russian river.
