Species of Frogs. 1 7 



maculate, white, the throat yellowish. Male with two inter- 

 nal vocal sacs. Size of Rana temporaries. 



This species is intermediate to Rana Catesbiana and R. 

 clamata.

Having examined the type specimen of Limnodytes mada- 

 gascariensis in the Paris Museum, I am able to state that Rana 

 inguinalis is identical with that species. The specimen re- 

 ferred bjme (Cat. Batr. Ecaud. p. 67) with doubt to R. mada- 

 gascariensis is identical with R.femoralis, Blgr. (I. c. p. 463). 



Scaphiopliryne marrnorata^ Blgr. 



Scaphiophryne marmorata, Boulenger, Cat. Batr. Ecaud. p. 472. 



Scaphiophryne spinosa, Steindachn. Sitzb. Ak. Wien, lxxxv. 1882, 

 p. 189, pi. ii. 



This frog was described from a half-grown specimen. The 

 British Museum has now received, through M. V. de Robil- 

 lard, an adult female, measuring 48 millim. from snout to 

 vent. S. spinosa is no doubt identical with this species, 



Pseudis rnantidactyla (Cope). 



Lysapsus rnantidactyla, Cope, Proc. Ac. Philad. 1862, p. 352. 

 Pseudis rnantidactyla , Boulenger, Cat. Batr. Ecaud. p. 187. 



The British Museum has received a specimen of thi3 species 

 from the Rio Grande do Sul through Dr. v. Iliering. I have 

 also seen several specimens in the Paris Museum, and ob- 

 tained one for the national collection ; these are from Monte 

 Video. I am able to add the following characters to Mr. 

 Cope's diagnosis : — The tips of the fingers are not dilated. 

 The hind limb being carried forwards along the body, the 

 tibio-tarsal articulation reaches the tip of the snout or slightly 

 beyond. This species is very closely allied to Pseudis minuta, 

 Gthr., but is to be distinguished by its dilated toes and shorter 

 hind limbs and the much developed external vocal bladders, 

 which are blackish and situated below the mandible, opening 

 by a slit, as in several species of Rana. The size is about 

 the same in the two species. The bones are green.
