FIG. 3 in Undescribed Diversity in a Widespread, Common Group of Asian Mud Snakes (Serpentes: Homalopsidae: Hypsiscopus)

FIG. 3. Morphological characters and variation of Hypsiscopus murphyi. (A–D) Holotype of H. murphyi (NCSM 85490) in preservative showing dorsal (A), ventral (B), and right lateral head (C) views, and hemipenes (D). Black scale bars represent 1 cm in panels A and B, and 2 mm in panels C and D. (E) Close-up of rear-fang of H. murphyi (AMNH R-33908). (F) Variation in melanin pigmentation of the infralabials and anterior chin shields: slightly pigmented (left; NCSM 85490) and heavily pigmented (right; ROM 32374). (G) Left two images, variation in dorsal-to-ventral color patten change: sharp (NCSM 85490) and gradual (ROM 30818). Right two images, variation in ventral color pattern: immaculate (NCSM 85490) and mid-ventral halfmoons (ROM 30818). (H) Variation in extent of mid-ventral caudal stripe, with stripe beginning on second subcaudal pair (AMNH R-33908) rather than the 13th subcaudal pair in the holotype (NCSM 85490; panel B).
