Hyla regilla, Brocchi, Miss. Se. Mex., Batr. p. 31, t. 13. fig. 2 (not B. & G.). 
Hyliola bocourti, Mocquard, Nouv. Arch, Mus. i. p. 841 (1899); Bull. Soc. Philom. (9) i. p. 164 
(1899). 
Hab. Mexico, Tepic (Diguet); Guatemata, Alta Vera Paz (Bocourt). 
Closely allied to Hf. eximia, but with the posterior face of the thigh ornamentally 
coloured. 
Vomerine teeth between the choane, in two transverse groups; choanse and 
eustachian ostia nearly equal. Snout of moderate length, rather depressed, with 
obtuse canthus and sloping sides, Distance of the nostril from the eye nearly as long 
as the diameter of the latter, and more than the distance of the nostrils from each 
other. Interorbital space wider than the upper eyelid. Tympanum distinct, one-half 
the area of the eye. Fingers free, with disks somewhat larger than those of the toes, 
and somewhat smaller than the tympanum. Toes barely one-third webbed; (tarsal 
fold, if present, quite indistinct). Upper parts smooth, lower granular. Upper parts 
bluish, with large blackish longitudinal spots, which commence between the eyes. 
Side of the snout blackish, which colour is continued as a band across the tympanum 
and along the side of the body; this band is sharply defined towards the back, and 
finely edged with white, but towards the abdomen it gradually passes in an irregular 
outline into the light coloration of the lower parts; it has also an incomplete whitish 
lower edge between the eye and the tympanum. Upper jaw without a horn-coloured 
border ; limbs indistinctly cross-banded, and the posterior face of the thigh is finely 
marbled with black and white on a greyish ground,

Hab. Mexico, Cuernavaca (fH. H. Smith). 
Vomerine teeth (sometimes indistinct or even entirely absent) between the choanee, 
in two fascicles; choanz wider open than eustachian ostia. Snout of moderate length, 
rather pointed, not depressed, with angular canthus and subvertical sides. Kye of 
moderate size, its diameter equal to its distance from the nostril, and more than the
