MYERS, Natural History Museum, Stanford University, California. In connection with some notes I have to present on the strange, casque-headed Hylid, Tetraprion, it seems desirable to record a few other species from Ecuador and Peru, one of them apparently undescribed. Most of the frogs form part either of a small Ecuadorian collection purchased by the Natural History Museum of Stanford University from Mr. William Clarke-Macintyre of Quito or of a rather extensive series received from my friend Mr. William G. Scherer of the Evan-gelical Mission at Pevas, Peru. The Pevas frogs were collected by Mr. Scherer's son, Paul Scherer, to whom I take pleasure in dedicating the new species. One of the Tetraprion was a gift from my former classmate, Dr. Donald L. Frizzell, of Negritos, Peru. Edalorhina perezi Jimenez de la Espada. One fine example (no. 5043) from Avila, Rio Napo, Ecuador, at 500 meters, May 1939, Wm. Clarke-Macintyre. This is one of the most unusual and delicately marked of frogs, and records of it are extremely rare. Eupemphix schereri, new species. Diagnosis. — A Eupemphix with a median tarsal tubercle, a variable series of lateral dermal glands in front of the groin, the upper surfaces rough with minute rounded spinescent warts of unequal size, a well developed lateral parotoid gland (without distinct superomedian border) behind the tympanum, tympanum dorsally obscured but its anteroventral half dis-tinct and its size two-thirds the diameter of the eye, a projecting snout, slender fingers with expanded rounded tips, first finger longer than the second, sole without tubercles except the two metatarsals and the normal strong subarticular ones on the free parts of the toes; tibiotarsal articulation reaching the eye when leg is brought forward, undersurfaces uniformly smooth, a large black inguinal spot which includes all or nearly 30— Proc.
