BIAWAK Quarterly Journal of Varanid Biology and Husbandry Volume 3 Number 4 December 2009 ISSN: 1936-296X On the Cover: Varanus cerambonensis The Varanus cerambonensis depicted on the cover and inset of this issue were photographed on Buru Island, Maluku province, Indonesia by Valter Weijola on 19 and 23 March 2009. Both specimens were encountered in mangroves on the eastern part of the island at 1250 and 1330 h, and measured approximately 100 cm (specimen pictured on cover) and 70 cm (specimen pictured below) in total length.. Belonging to the V. indicus species group, V. cerambonensis was described in 1999 (Philipp, K.M., W. Böhme and T. Ziegler. 1999. The identity of Varanus indicus: redefinition and description of a sibling species coexisting at the type locality [Sauria: Varanidae: Varanus indicus group]. Spixiana 22[3]: 273-287.), and is reported to occur on several neighboring islands within the central Moluccas, including Ambon, Banda, Buru, Obi, and Seram. Field observations of V. cerambonensis have been scarce, and little has been published on its natural history and occurrence. 94 BIAWAK Quarterly Journal of Varanid Biology and Husbandry Editor Editorial Review ROBERT W.
