AMCS Bulletin 8 Jointly published as Texas Memorial Museum Bulletin 28 Further Studies on the Cavernicole Fauna of Mexico and Adjacent Regions Edited by James R. Reddell 1986 (AMCS reprint 2006) 8.5 by 11 inches, 288 pages softbound

Among the many taxa described in this volume are fifty new species and subspecies of troglobite from Mexico. This brings the number of described troglobites in Mexico, Guatemala, and Belize to 330. Many of the newly described taxa are from the Purificación cave area in Tamaulipas and Nuevo León, the Huautla region in northern Oaxaca, or the Cuetzalan area in northern Puebla.
