Stanley Rand Biological Laboratories, Harvard University Among the reptiles and amphibians collected for the Museum of Comparative Zoology in Haiti, with the support of an Ameri-can Philosophical Society grant, during the summer of lfJ60, are seven specimens that appear to represent an undescribed species of Anolis. These lizards are small, moderately proportioned, dull colored in life, as well in preservative, and rather nondescript animals. In life the adult males possess a dark gray gular fan and an orange-pink chin and throat that distinguish them immediately from any otlier Hispaniolan Anolis. When this chin and throat color disappears in alcohol, the combination of scale characters distinguishes the species, but there are no unique characteristics. Dr. Karl Koopman, Assistant Curator of Mammals, Chicago Natural History Museum, provided financial assistance and encouragement that helped to make the collection of these specimens possible. In recognition of his aid the new species is called : Anolis koopmani new species Type. MCZ 62541, adult male. Type locality. Carrefour Canon, 350 m. altitude, near Ducis, N. of Aux Caves, Haiti.
