Hylodes hallowellii. 



Head and body rather elongate. Muzzle thick, prominent. Canthus ros- 

 tralis obsolete. Tympanic disc half the size of the eye. Vomerine teeth much 

 behind the internal nares, in two short, transverse, slightly curved series. 

 Tongue thick, elongate, oval, entire. Ostia pharyngea round, a little larger 

 than internal nares. Skin of the under surfaces smooth ; sides rugulose, with 

 a few tubercles ; a few rugosities on the posterior dorsal region, and some folds 

 upon its borders. A strong fold from the orbit above and behind the tympanum. 

 Numerous delicate folds npon the anterior face of the femur ; a posterior tarsal 

 fold. Palm smooth, a large median metacarpal tubercle, and a very prominent 

 elongate one on the base of the inner digit. A rudimentary web between all 

 the toes of the hinder extremity ; the metacarpal tubercles two, small, the 

 internal narrow. Femora very stout. Heel extending to the orbit. Length of 

 head and body 1 in. 6 1. Width of head at canthus oris 6 1. Length of hinder 

 extremity 2 in. 3 1. 



Above grayish brown, with a reddish tinge. A light band between the eyes, 

 from which one descends on the end of the muzzle to the labial border. A 

 light line from the nostril to the labial border, two from the anterior border of 

 the orbit, and one from the posterior. A dark shade upon the occiput. Chin, 

 thorax, sides and inner borders of extremities marbled with brown. Two brown 

 bands on the tibia; one broad and several narrow bands on the femur. 



Habitat. Near Carthagena, New Granada. Mus. Smithsonian, (No. 4343.) 

 From Lieut. Michler's Expedition. 



A near ally of H. fitzingerii Schmidt, with which it ought, perhaps, to 

 be removed from this genus. 



It is dedicated to the memory of the late Dr. Edward Hallowell, whom the 

 author holds in grateful and respectful recollection. 



The genus Hylodes, as understood by Dumeril, embraces twenty-three 

 species, including those here described. They naturally associate themselves 

 round several types, forming the following groups. 1. Craugastor Cope. Toes 

 very slightly webbed. Vomerine teeth in two short, transverse series behind 

 the internal nares. Skin of the abdomen smooth. H. hallowellii and 

 fitzingerii. 2. Hylodes Fitz. Toes entirely free. Vomerine teeth in two 

 short, oblique series behind the internal nares. Skin of the belly (typically, 

 granular. H. martinicensis, auriculatus, ?conspicillatus) 

 ?parvus (belly smooth.) 3. Lithodytes Fitz. Toes free. Vomerine teeth in 



1862.]
