Distributional records and taxonomic notes are presented for the following seven species of rare or little-known skinks from the Mexican states of Chihuahua and Durango: Eumeces brevirostris bilineatus, E. callicephalus, E. lynxe durangoensis, E. multilineatus, E. multivirgatus, E. obsoletus, and E. parviauriculatus. E. lynxe durangoensis Tanner is a junior synonym of E. lynxe belli (Gray). E. multivirgatus mexicanus Anderson and Wilhoft is probably a junior synonym of E. multilineatus Tanner. In the collections of reptiles and amphibians made in northern Mexico by summer field expeditions of the University of Kansas Museum of Natural History since 1955, there are some noteworthy specimens of scincoid lizards from Chihuahua and Durango. EUMECES BREVIROSTRIS BILINEATUS Tanner. Data for five specimens from Chihuahua are as follows: KU 44262-3, 15 mi. S and 6 mi. E Creel, 7300 ft., July 16, 1957, and KU 47429, 2 mi. W. Samachique, 7000 ft., July 11, 1958 (juveniles); and KU 51324-5, 2 mi. W. Samachique, 7000 ft., July 11-12, 1958 (adults). The five specimens provide additional information on variation in this recently described subspecies and extend its known range slightly eastward in Chihuahua. The juvenal specimens differ from two juvenal paratypes of bilineatus (KU 44728 and 44730) from the region of El Salto, Durango (paratype from Mojarachic, Chihuahua, not examined), as follows: markings on anterior part of body having greater contrast; dorsolateral lines paler and wider, most distinct anteriorly but easily discernible to insertions of hind limbs; dorsal field between pale lines uniformly metallic, tannish gray (more evident in specimens from Creel than specimen from Samachique); tail bright blue; a distinct, wide, dark stripe on side of body, bordered above by pale dorsolateral line and below by silverish color of belly. Colors of the two adults fall within the range of variation seen in the holotype and four adult paratypes (KU 44726-7, 29, 31-32). One of the adults from Samachique (KU 51324) was giving birth to young when caught;
