Color dark brownish-leaden, below dirty white. The almost black of the 

 sides bounded below by an irregular pale border, below which are some dark 

 marblings. The same border extends, with an axillary interruption, to the 

 orbit, and continues on the upper lip as a series of light dots. A light band 

 commences at the groin above, and extends to opposite the sacrum, convert- 

 ing the dark color of the side into a half band. Femur and tibia dark, marbled 

 before and behind. 



From the river Truando, New Grenada. Brought by the expedition under 

 Lieut. Michler, by Arthur Schott. This species and the Dendrobates tinc- 

 t o r i u s Wagl. were accidentally omitted from the report of this expedition, 

 published in Proc. Acad. 1862, 355. 



BUFO ARGILLACEUS CopC, Sp. nOV. 



Ridges of cranium superciliary and supratympanic ; no parietal branch. 

 Parotoids elongate trigonal, the long angle prolonged towards the sides. Two 

 weak metatarsal tubercles. A tarsal dermal fold ; toes little webbed. Muzzle 

 elongate, not much depressed or projecting beyond labial border. No pre- 

 orbilal ridge; superciliaries nearly parallel. Skin rather finely rugose. 



Males olive-grey ; females with a pale vertebral line, and a series of brown 

 spots on each side of it. Crown, lips, and below unspotted. Length of head 

 and body 2 in. 9 1. 



This species is to be compared with the B. granulosus of Spix, which 

 it represents in another region. It differs in lacking the preorbital ridge, and 

 having a longer muzzle. 



Numerous specimens in Museum Smithsonian from Colima, "Western Mexico, 

 from U. S. Consul, John Xantus. 



Second Supplement on some New Raniformia of the Old World. 



TOMOPTERNA LABROSA Cope, Sp. nOV. 



Head rauiform, little elevated ; end of muzzle recurved, loreal and subor- 

 bital regions concave, the edge of the maxillary region strongly projecting. 

 From orbit to margin of jaw below it less than diameter of tympanum, two- 

 thirds that of orbit. Tympanum elliptic, subvertical, about -66 long diame- 

 ter eye fissure, latter -2 greater than from edge of same to external nostril, 

 and 1-5 least interorbital width. Frontal and prefrontal regions slightly 

 grooved medially. Vomerine teeth in two very short, nearly transverse, lines 

 opposite the middle margin of the inner nares. Latter large, about equal to 

 ostia pharyngea. 



When the limbs are extended the carpus attains the end of the muzzle, 

 and the heel the middle of the orbit. Tarsus equal third toe without last 

 two phalanges. Cuneiform shovel small for the genus, equal inner toe less 

 the last phalange. Webs large, measuring "66 the third and fifth toes. 

 Thumb longer than second and fourth fingers. Skin of upper surfaces with 

 numerous nMrrow irregular folds ; eyelids slightly rugose behind. A strong

 vertebral band. The anterior of these are a triangular blotch on top of muz- 

 zle and band across middle of each eyelid. Side of head blackish-gray with 

 a pale gray band on end of muzzle, one from front of orbit to lip, and one
