Among collections recently presented to the Natural History Museum of Stanford University through the great kindness of Sr. Gutavo Orces V. of the Escuela Politecnica Nacional, Quito, Ecuador, is a single example (SU 10363) of a noteworthy caecilian. The specimen, 159 mm. in length, is from the Rio Cotapino (Cotopino), between 00 40' and 00 44' south latitude and 770 10' and 770 20' west longitude, at an altitude of 380-450 meters, Napo-Pastaza Province, Ecuador. The significant characteristics of this beast are: primaries 124, secondaries 59, length divided by diameter of body 32, tentacle slightly nearer eye than nostril, eye visible and body uniform grayish with the head markedly lighter. In all these features the specimen clearly belongs to the species Gymnopis albiceps Boulenger (1882:98, pl. 8, fig. 1) as defined by Dunn (1942:472). The species has previously been known from two examples, the type from "Ecuador" and a second example from Santiago-Zamora Province, Ecuador. The Stanford caecilian extends the known range of the species approximately 100 miles northward and suggests that atbiceps has a wide distribution in the Oriente of Ecuador.
