Mexico and Central America, the Thorius pennatulus Cope, and the two 

 species of CEdipina (Opheobatraclius). Besides the generic characters, it 

 differs from the latter in the shorter and compressed tail, etc. From the 

 former it differs in the larger number of costal folds, smaller nostril, and 

 in coloration, etc. The single specimen was found at Palma, and is 

 No. 293 of the collection.

 PJiilos. Soc, 1885, p. 275. 

 This species differs from the L. rugulosa Cope {Proceeds. Amer. 

 PMlos. Soc, 1869, p. 160) in its more elongate muzzle and in the 

 smaller and differently shaped tympanic membrane. In the L. rugu- 

 losa the membranum tympani is round, and is about equal to the eye ; 

 while in the L. ranoides it is a vertical oval of about half the same diame- 

 ter. The belly of the L. ranoides is free from rugosities. 



Three specimens of this species are in the collection, and they are very 

 dissimilar in coloration, and neither of them resembles the type. They 

 may be arranged thus. 

 I. Light gray ; no dorsal stripe or interocular cross-band. No. 333, near 

 Buenos Ayres. 

 II. Dark brown, a light interorbital crossband, and black W-shaped 

 mark on interscapular region. No dorsal stripe. Type from Nica- 

 ragua. No. 14,179, U. S. National Museum. 



III. Dark brown, with a pale, narrow dorsal line, and pale interocular 

 cross-band. No. 288, Terraba. 



IV. Dark brown above with a broad pale dorsal stripe, as wide as the 

 internareal space. No interocular cross-band. No. 304, Buenos 

 Ayres. 



These speQimens agree in having four dark spots on the upper lip, of 

 which the anterior is below the nostril ; in the legs being marked with 

 a few dark-brown cross-bands ; and in the femur being obscurely mar- 

 bled behind. The vomerine teeth are close together, entirely within the 

 interior border of the internal nares, and much posterior to the latter. In 

 No. 304 the dorsal integument displays a fold from cranium to sacrum on 

 each side of the wide dorsal stripe ; on the external side of each of these 

 anteriorly three short folds extend upwards and backwards from the 

 orbit. 



No. 288 is a female, and resembles in color the Lithodytes melanostictus 

 Cope {Journal Phila. Acad., 1875, p. 109), which is from alpine
