230 BATRACHIA SALIENTIA. 
5. Hylodes calcitrans, sp.n. (Tab. LXVII. fig. B.) 
Hab. Mexico, Omilteme in Guerrero (H. H. Smith), Jalisco (Richardson). 
Body rather stout, its length exceeding the distance between vent and heel; snout 
rather broad, but pointed in front, with sloping sides and distinct, curved canthus. 
Tympanum two-thirds the size of the eye. Vomerine teeth in two short oblique 
groups behind, and within the level of, the choane. Upper parts smooth, abdomen 
granular. Tips of the fingers and toes scarcely dilated. First and second fingers 
subequal. Subarticular tubercles well developed, but not continued on the metatarsals. 
Two metatarsal tubercles, of which the inner is unusually large, projecting, nearly as 
large as the tympanum. Toes short. No tarsal fold. Coloration variable. Upper 
part of the snout light-coloured, separated by a dark interorbital band from the colour 
of the back, which is generally brownish-grey marbled with a darker tint. A blackish 
band along the canthus rostralis sometimes extends over the whole side of the head, 
and may be continued on the side of the body. Limbs with narrow cross-bars, which 
sometimes encroach upon the concealed hinder surface of the hind limb. The darker 
spots on the back are sometimes confluent, and form a pair of longitudinal bands. 
Lower parts whitish, throat brownish.

Numerous examples show all the unusual development of the inner metatarsal 
tubercle, but in specimens from Jalisco the granulation of the abdomen is less 
conspicuous, possibly owing to their imperfect state of preservation. 
6. Hylodes platyrhynchus, sp.n. (Tab. LXVII. fig. A.) 
Hab. Costa Rica (Mus. Nac. de Costa Rica). 
- Head large, broad, its width being increased by the loreal region, which, instead of 
being subvertical, slopes outwards in a very oblique plane; canthus rostralis distinct. 
Posterior half of the abdomen granular and finely areolated. Eyes obliquely directed 
forwards. ‘Tympanum one-third the size of the eye (in a female). Vomerine teeth in 
two long, straight, subcontinuous series behind the choane, and laterally extending to 
the level of the inner margins of the choane. Upper parts nearly smooth, with the 
exception of a linear fold above and round the tympanum, and another from the eye 
curving towards the middle of the side of the back ; some small tubercles on the hinder 
half of the superciliary region. Disks of the fingers well developed, truncate, larger 
than those of the toes. First finger a little shorter than second. One metatarsal
