It is probable that the eel descends rivers in October and November, spawning in the autumn and early winter at the mouth of rivers, and in harbors and estuaries in sliallow water. By the end of tlie spring the young eels are two or three inches long, and then ascend rivers and streams. They grow about an inch a month, and the females do not s]>awn at least before tlie second year, , when about twenty inches 1 g. Mr. Mather estimates that the ovary of an eel weighing six pounds when in spawn contains upwards of 9,000,000 eggs. Order 3. NemaiognatM (Catfish, Pouts, etc.).—The.
