III-IV PACIFIC ISLANDS HERPETOLOGY, NO. V GUADALCANAL, SOLOMON ISLANDS: A CHECK LIST OF SPECIES ( l ) VASCO M. TANNER Professor of Zoology and Entomology Brigham Young University Provo, Utah INTRODUCTION This paper, the fifth in the series, deals with the amphibians and reptiles, collected by United States Military personnel while they were stationed on several of the Solomon Islands. These islands, which were under the British Protectorate at the out-break of the Japanese War in 1941, extend for about 800 miles in a southeast direction from the Bismarck Archipelago. They lie south of the equator, between 5° 24' and 10° 10' south longitude and 154° 38' and 161° 20' east longitude, which is well within the tropical zone. In this study, eleven large islands are considered as composing the Solomon Archipelago, which form two chains. The northern row of islands consists of Buka and Bougainville, just south of New Brit-ain. Next is Choiseul, followed by Isabel and Malaita. The southern group, which practically parallels the northern row, consists of Vella Lavella, Kolombangara, New Georgia, Russell, Guadalcanal and San Cristobal. Bougainville is the largest island of the group. It has a surface area of 3,900 square miles, the highest mountain peak, Mount Bally, 10,000 feet and also active volcanoes. Guadalcanal, 2,500 square miles, is the largest island in the southern row with a peak over 8,000 feet high (see map fig. 1). (1) Contribution No. 127 from the Department of Zoology and Entomology.
