A NEW SKINK OF THE MITLTIVIRGATUS GROUP FROM CHIHUAHUA Wihner W. Tanner' A skink, USNM 30833, taken by the Brimley brothers in Cliihuahiia. Mexico, has, for lack of a better understanding of its relationships been heretofore associated with the multivirgatus complex. Taylor (1935:352) and Smith and Taylor (1950:166) suggested its apparent distinctness but because of a badly faded color pattern hesitated to describe it as new. In July. 1931, D Elden Beck took a subadult at Colonia Garcia, Chihuahua. In August, 1957, the author secured an adult at Col-onia Chuhuichupa. Chihuahua. A study, of these three sepcimens and a comparison of them with multivirgatus from Arizona. New Mexico, Utah and Colorado, has demonstrated significant color and scale pattern differences. I, therefore, propose that this new skink be known as Eumeces multilineatus, n. sp. Type: Brigham Young University No. 13798, collected by Wilmer W. Tanner and Gerald Robison, 3 miles north of Colonia Chuhuichupa, Chihuahua, Mexico, on August 26, 1957. El. 7500 ft. Paratypes: Brigham Young University No. 11984, from Col-onia Gracia, Chihuahua, Mexico, by D Elden Beck, July 12, 1931; U. S. National Museum No. 30833, from Chihuahua. Mexico, col-lected by H. H. Brimley and C. S. Brimley. Diagnosis: A Eumeces of the multivirgatus group, of similar size, body and limb proportions as in multivirgatus. Postnasals ab-sent; frontonasal nearly twice as wide as long; interparietal not enclosed; seventh supralabial separated from ear opening by one pair of enlarged postlabials; median ventral caudals approximately three times as wide as long; color pattern consisting of five primary light lines over a dark ground color; median line on inner third of first scale row, followed laterally by a dark stripe on median third of first scale row. Scales between dorsolateral and lateral light stripes a uniform blackish color. Description of the type: Rostral normal, in contact with first supralabials, nasals, and internasals; two internasals followed by a frontonasal, nearly twice as wide as long; prefrontals widely sutured; frontal large, only slightly wider anteriorly than post-eriorly, the latter part rounded; four supraoculars, second largest; frontoparietals smaller than interparietal, the latter arrowshape; parietals large, nearly in contact with j)rimary temporal, not enclos-ing interparietal; two pair of muchals of equal size; nasal divided, anterior part slightly larger; anterior loreal higher than long, pos-terior longer than high, anterior scale in contact with first and second labials, nasal, internasals, frontonasals, prefrontals and 1.
