Mr. G. A. Boulcngcr on American Batrachians. 455 



\vl)ich I examined tlie specimen in tlic Berlin Museum. I 

 further find that Olohjgon or Thoropa miliaris is not a Ilyloid 

 but a Cystignathoid, and tliat it agrees in all essential points 

 Avith Jwrboroccetes, J^ell. The diapophyses of the saeral 

 vertebra are feebly dilated, just as in IJ. Bibrom'i, Oraiji, and 

 quiaxnsis. I aj)pend a description taken from the speeiniens 

 in the Berlin and Copenhagen Museums. 



Tongue subeircular, slightly nicked behind. Vomerine 

 teeth in two short transverse series on a line with the poste- 

 rior border of the ehoante. Snout rounded, as long as the 

 diameter of the orbit ; canthus rostralis obtuse, lorcal region 

 concave ; nostril much nearer the end of the snout than to the 

 eye ; eye large ; interorbital space as broad as the upper 

 eyelid ; tympanum very distinct, two thirds or three fourths 

 the diameter of the eye. Fingers moderate, first slightly 

 longer than second ; toes moderate, quite free, not fringed ; 

 subarticular tubercles moderately developed ; two metatarsal 

 tubercles, inner elliptical, outer round. The tibio-tarsal 

 articulation reaches the tip of the snout or a little beyond. 

 Skin smooth, with a few glandular warts on the sides ; a 

 strong fold from the eye to the shoulder. Pale greyish or 

 brownish above, with darker marblings ; a large triangular 

 spot, base forwards, between the eyes ; a bhickish line along 

 the canthus rostralis and temporal fold ; hind limbs with dark 

 cross bars ; hinder side of thighs dark brown, with yellowish 

 spots ; lower parts pale brown, throat and belly dotted with 

 yellowish. 



From snout to vent 45 millim. 



Ci/sti(jnathus /ij/hdes, described in the same paper with 

 C. disco/or by Keinhardt and Liitken, is based on young 

 specimens of Lcptodactylas pentadactylus. 



Bufo Luetkeniij sp. n. 



Intermediate between B. vcdliceps, Wiegm., and B. granu- 

 lukus, Daud. Crown deeply concave, witii prominent ridges, 

 viz. a canthal, a preorbital, a supraorbital, a postorbital, a 

 parietal, and an orbito- tympanic ; parietal ridges short, 

 oblique, directed inwards ; snout rounded, not prominent ; 

 interorbital space at least as broad as the upper eyelid ; tym- 

 panum very distinct, two thirds or three fifths the diameter 

 of the eye. First finger considerably longer than second ; 

 toes half-webbed, with single subarticular tubercles ; two 

 small metatarsal tubercles ; no tarsal fold. The tarso-meta- 

 tavsal articulation reaches the tympanum or the eye. Upper 

 parts with small irregular warts ; parotoids very small, oval.
