Original description Head semi-elliptical, somewhat convex, with the muzzle nearly perpendicular; vertex smooth. Eyes of moderate size. Nostrils very small, opening upwards. Tongue broad and rounded behind, narrowing to a point at the apex, detached at the posterior part. Palatine teeth in two small approximate patches, between the posterior nostrils. Openings of the Eustachian tube scarcely visible. Extremities of moderate length. The fore feet, with four rather short toes, connected at the base by a short membrane; the inner toe broad, and with a slight projection under the skin, along its inner margin; hinder toes connected as far as the joint of the second and third phalanges. The colour of the only specimen in the collection has become totally changed into a smoky brown by the spirit, but the following Mr. Darwin's description of it when living: "On the centre of the back a strong tinge of grass-green, shading on the sides into a yellowish brown; iris coppery." Dimensions (In. lines): Length of the head 0.5; of the body 1.0; of the anterior extremities 0.9; of the posterior extremities 1.8.

MATERIAL.—KU 160574 (two specimens dissected, description based on specimen stage 34, SVL 25.7 mm). Collected from Lago Nahuel Huapi, Neuquén, Argentina.

REFERENCE.—Lavilla, 1983, describes the external morphology.

GENERAL MATERIAL.—KU 162244 (one specimen dissected, stage 37, SVL 28.6 mm.) Collected from Parque Nacional Nahuelbuta (Cabrerías), 1030 m, Malleco, Chile. Specimen disintegrated prior to illustration.

REFERENCE.—Formas (1981b) indicated that the Kansas series of specimens from Cabrerías represents a new species being described by Alberto Veloso, who is presumably describing the external morphology of the tadpole.

GENERAL

Alsodes monticola (common name: island spiny-chest frog) is a species of frog in the family Alsodidae. It is found in southern Chile and western Santa Cruz Province, Argentina, though its presence in Argentina is disputed. Its habitat preferences are not known, but the region of the type locality (the island of Inchy, in the Chonos Archipelago) has tundra and islands of Nothofagus forest.
