TWO NEW SKINKS FROM DURANGO, MEXICO Wilmer W. Tanner' Among tho reptiles secured in the state of Durango by the Uni-versity of Kansas field survey under the direction of Dr. Rollin Baker, for the summer of 1955. are specimens belonging to two species of the genus Eumeces. Four specimens of Eumeces lynxe Wiegmann were taken approximately 30 miles east of El Salto, and seven specimens of Eumeces hrevirostris Gunther were collected 9-15 miles southwest of El Salto. Both species were taken during the last week of June, while the area was still relatively dry. We worked these same areas during the first week of September (rainy season) 1957, without finding a single skink Although E. hrevirostris has been taken pre-viously in southern Durango (Coyote), the discovery of E. lynxe is a substantial range extension for this species. A careful examination of these specimens has demonstrated a modification of several characteristics which inarks them as distinct geographic subspecies. Eumeces lynxe durangoensis, n. subsp. Fig. 1 Type.-— An adult female, KU 044737, taken approximately 30 miles east of El Salto, Durango, Mexico. Collected by C. M. Fugler, June 30, 1955. Paratypes — KU 044734-5 topotypes and KU 044736 taken ap-proximately 10 miles east of El Salto, Durango. All types are in the vertebrate collection of the University of Kansas Museum of Natural History. Diagnosis. — A moderate to small form with the tail approximat-ely 60 per cent of the total length. Median stripe extending from the shoulders to the frontal plate where it terminates without bifurcat-ing. Lateral stripe absent and dorsolateral stripe distinct anteriorly but becoming faint at middle of body and obsolete posteriorly. Seven superciliaries. the anterior one in broad contact with the prefrontal, frontonasal nearly as long as wide and the postloreal noticeably longer than high. Description of type. — Rostral normal, in broad contact with the first supralabials. nasals, and internasals; two internasals followed by a frontonasal slightly wider than long and in wide contact with the frontal; prefrontals larger than internasals and in contact with both loreals. first superciliaries, first supraoculars, frontonasal and frontal; four supraoculars, second largest; seven superciliaries. first and seventh largest, first in broad contact with prefrontal, seventh higher than long, and forming a broad contact with fourth supra-ocular; frontal large, widest anteriorly, rounded posteriorly and in contact with the first three supraoculars; frontoparietal smaller than interparietal and in broad contact; parietals large, nearly enclosing the smaller interparietal; nasal elongate, divided and with the nostril near its middle; postnasal absent; anterior loreal higher than long, 1.
