Show 540 ON REPTILES ETC. F R O M WESTERN SOMALI-LAND. [June 18> 4. CHIROMANTIS PETERSII, Blgr. A fine female specimen, measuring 80 millim. from snout to vent. Darar, 15.9.94. 5. CASSINA OBSCURA, Blgr. A single specimen from the Budcla Plateau. The tarso-metatarsal articulation reaches the shoulder. Toes one-third webbed. Skin nearly smooth above. Olive-green above, with dark liver-brown spots. 6. CACOSTERNUM NANUM, Blgr. A single specimen. Durro, 2.12.94. The occurrence so far north of this species, originally described from Caffraria (Ann. & Mag. N . H . [5] xx. 1887, p. 61), is surprising. Yet I have little doubt the determination is correct. 7. BUFO REGULARIS, Reuss. Numerous ; collected all along the route. 8. BUFO DODSONI, sp. n. (Plate XXX. fig. 5.) Crown without bony ridges ; snout short, blunt; interorbital space as broad as the upper eyelid ; tympanum very distinct, two thirds the diameter of the eye. First finger considerably longer than second; toes one-third webbed, with single subarticular tubercles; two moderate metatarsal tubercles; a tarsal fold. The tarso-metatarsal articulation reaches the anterior border of the eye. Upper parts with numerous flat, distinctly porous warts; parotoids oval, flat, as long as their distance from the anterior border of the orbit. Pale olive above, with small darker spots; a dark canthal streak and a dark vertical bar below the eye; lower parts white. Male with an internal subgular vocal sac. From snout to vent 53 millim. A single male specimen. Rassa Alia, 6.10.94. This species, which is allied to B. viridis, Lain*., is named after Mr. E. Dodson, who accompanied Dr. Donaldson Smith as taxidermist. 9.
