THE UNIVERSITY OF KANSAS SCIENCE BULLETIN Vol. XXII. 1 April 15, 1935 [No. 9. Coleonyx jasciatus, a Neglected Species of Gecko By EDWARD H. TAYLOR IN THE first volume of the catalogue of the lizards in the British Museum, published in 1885, Boulenger described as new a speci-men of a gecko which he named Eublepharis jasciatus. This speci-men was collected by Forrer in Ventanas, Durango, Mexico. The description is brief and probably because of this brevity and re-sultant lack of distinguishing characters, Stejneger (North American Fauna No. 7, 1893, p. 163) placed the species in the synonymy of Coleonyx variegatus (Baird). Gunther (Biol. Cent, Amer., April, 1893, p. 83, pi. 31., fig. A) gives a somewhat better description, together with a good figure of the entire animal, and an enlarged drawing of the head. This latter paper apparently was not seen by Stejneger prior to his synony-mizing the two forms. Van Denburgh (1923) likewise follows Stejneger in placing this form in the synonymy of C. variegatus. In the summer of 1934, at a locality about 15 miles south of Presidio, Sinaloa, Mexico, I collected a male specimen of what ap-peared to be Boulenger's species. However, to make certain its identity, I sent the specimen to Mr. H. W. Parker of the British Museum, who compared it with the type. He states: "I have com-pared it with Boulenger's type of C. jasciatus and have no hesitation in saying that the two are conspecific. I do not think there can be any question that the type, far from being a juvenile C. brevis, is a full-grown female of a distinct species." Since only this single other specimen (the type) is known, and the descriptions of this brief, I offer the following data on the speci-men in my collection (No. 556). (203)
