202 BATRACHIA SALIENTIA. 
Werner (Jahresb. naturw. Ver. Magdeburg, 1894, p. 128) places this frog among the 
synonyms of R. halecina; but if it is correctly described (and description and figure 
agree tolerably well), it must be a distinct species, apparently of the 2. sylvatica type. 
7. Rana pustulosa, (Tab. LXI. fig. B.) 
Rana pustulosa, Bouleng. Ann. & Mag. N. H. 1883, xi. p. 343. 
Hab. Mexico, Ventanas in Durango (Forrer). 
Form of the body moderately robust ; head of moderate size, with broad and rounded 
snout; canthus rostralis angular; loreal region high and concave. Tympanum half 
the size of the eye. Vomerine teeth in two short oblique series extending to behind 
the level from the hind margin of the choane. First finger extending beyond the 
second. ‘Toes with very broad web, reaching the last phalanx of the fourth toe. ‘Tips 
of the toes slightly swollen. An inner small metatarsal tubercle. Hind limb, without 
tarsus, shorter than, fourth toe (from metatarsal joint) half as long as, the body. Back 
with a narrow glandular fold; skin of the upper parts covered with small pustules. 
Greyish-brown, with indistinct blackish spots; limbs indistinctly barred. Lower parts 
dull yellow, throat marbled with blackish. An indistinct light line runs along the 
upper lip and side of the abdomen. 
The measurements of an adult female are: — 
Distance between snout and vent . . . . . . . . 110 millim. 
Diameter oftympanum. . . . . . . 6, 
Length of hind limb to tibio-tarsal jomt . . . . . . 96 ,, 
3 fourth toe from metatarsal jommt . . . . . 56 ,, 
Some small frogs collected by Dr. A. C. Buller at the Hacienda Santa Gertrudis, 
Jalisco, may possibly be the young of this species ; their snout is, however, more pointed ; 
the skin shows only minute asperities; the web reaches only the penultimate joint. 
A whitish line runs along the glandular fold, and another, broader and more distinct, 
along the upper lip and side of the abdomen.

The synonymy as given above is that compiled by Peters, Cope, and Boulenger ; 
but I am not satisfied that the different names and descriptions really refer to the same
