Mr. G. A. Boulenger on Batracliians. 389 



I now find that the account of 8. gibhosum with the reversed 

 shoukler-gh-dle was taken from a mounted skeleton in Hyrtl's 

 collection, which was purchased by the museum of the Col- 

 lege of Surgeons. This specimen was prepared with the 

 • pectoral arch upside down. 



Leptodactylus gracilis, D. & B. 



Several specimens were sent by Dr. v. Ihering from the 

 province Eio Grande do Sul which agree perfectly with 

 Bibron's description. Hensel was therefore right in referring 

 his specimens to L. gracilis, and I was wrong in including 

 his note in the synonymy of L, typhonius. 



Tongue oval, indistinctly nicked behind. Vomerine teeth 

 in two slightly arched series behind the choanse, separated by 

 a very narrow interspace. Snout acuminate, longer than 

 the diameter of tlie orbit ; nostril nearer the tip of the snout 

 than the eye ; interorbital space nearly as broacT as the upper 

 eyelid ; tympanum two thirds the width of the eye. First 

 finger much longer than second ; toes slender, not fringed ; 

 subarticular tubercles well developed; mner metatarsal 

 tubercle very small ; outer metatarsal tubercle very indistinct 

 or absent. The hind limb being carried forwards along the 

 body, the tibio-tarsal articulation reaches beyond the tip of 

 the snout. Skin smooth, with longitudinal folds along the 

 back, the outer one on each side being the most developed j a 

 ventral discoidal fold. Brown or olive-brown above, with 

 black spots more or less confluent into longitudinal bands on 

 the body ; a pale brown vertebral band ; a black streak from 

 the tip of the snout, through tlie eye, to the tympanum, and 

 another bordering the upper lip ; limbs with irregular cross 

 bars ; hinder side of thighs with large black marbiings, more 

 or less confluent into longitudinal bands ; beneath white, 

 immaculate, Male with an internal vocal sac ; thumb without 

 spinose tubercles. 



Bufo arenarum, Hens. 



On comparisoli of a small specimen from Gatamarca, pre- 

 sented to th.e Natural History Museum by Lord Dormer, with 

 the description of B. meridoclnus. Philippi, Arch. f. Naturg. 

 18G9;, p. 44, I am convinced that the latter is to be referred 

 to the synonymy of B. arenarum. 



Hyla rubra, Daud. 



Several larv^, including stages sufficiently advanced to 

 permit of naming the species, were collected at liecife, Per- 

 nambuco, by the late W. A. i^'orbes.
