Taylor (1922a, 1922b, 1922c, 1922d) consistently reported that this species was collected in montane habitats in primary forest and usually was associated with rocky stream beds on Luzon and its land-bridge satellite island of Polillo (Fig. 2).

Taylor's extensive work in the Philippines that specimens of H. philippimtm with reliable locality data became available. Taylor (1922a, 1922b, 1922c, 1922d) consistently reported that this species was collected in montane habitats in primary forest and usually was associated with rocky stream beds on Luzon and its land-bridge satellite island of Polillo (Fig. 2). Still, Taylor (1922b:200) considered the species rare and only obtained eight specimens in two years of nearly continuous field work. During the nearly 80 years that have elapsed since Taylor's work, several additional specimens of H. philippinum have been collected on Luzon and its associated land-bridge islands (Marinduque, Polillo, and Catanduanes; see Specimens Examined; Fig. 2). During the same period, none have been found on Mindanao, Mindoro, or any of the other Philippine islands, thus bolstering the notion that H. philippinum is endemic to the Luzon Pleistocene Aggregate Island Complex (Fig. 2; sensu Heaney, 1986; Alcala, 1986; see also comments by Leviton, 1963). In 1992, while participating in the National Museum of the Philippines/Cincinnati Natural His- tory Museum Philippine Biodiversity Inventory (PNM/CMNH PBI), one of us (RMB) collected speci- mens of what appeared to be a distinctive new species of snake, similar to but obviously specifically distinct from H. philippinum, at 1025 m elevation on the west face of Mt. Madja-as, Panay Island. In addition to rep- resenting a previously unrecognized species, this specimen appears to be the first vouchered record for the genus on the Visayan Aggregate Island Complex (Fig. 2; Heaney, 1986; Hall, 1996, 1998). During the course of this study we examined all available US and Philippine museum collections of//, philippinum and. â ;;*â¢,. Please note that these images are extracted
