Widi Plate. The type of this muray (201 A) from El Modena, diatomaceous shale, was sent to me by Dr. Gilbert, a lower-jaw, ZlA inches long. It is slender, straight, curved upwards toward the tip, and shows a single row^ of strong, conical sharp teeth, somewhat thickened at base, rather close-set, the interval being a little more than half the length of a tooth. The teeth on the middle of the jaw are a little larger than the others, those in the posterior third of the length are more slender, close-set and apparently in a band, rather than a single row, all the teeth directed more oi less backward. There is no trace of lancet-like teeth or of canines. Tip of the lower jaw apparently turned upwards. On. the fossil are traces of the teeth of the other or right side of the jaw, indicating that the mouth was narrow as well as long. Another half of a lower jaw (200A) also from El ^lodena, retained by Dr. Gilbert, is slightly larger, but shows no differ- ence. The type specimen was obtained from the fossil collection of Mr. E. E. Hadley. Another lower jaw from a much larger fish (No. 571) sent to me from Alhambra, Los Angeles County, by Mr. E. E. Had- 29.
