 Range. — From Guanajuato and Nayarit, southward to Jalisco, 

 Mexico. 



Remarks. — Professor Cope *^ states that — 



The Hylodes augusti (Duges, MS.), Brocchi Mision Scientifique de Mexique, 

 1881, from Guanajuato, Mexico, is related to the present animal [i. e., Eleuthero- 

 dactylus latrans]. I do not know what the specific diflFerence is, unless it be in 

 the form of the vomerine patches, which I can not clearly make out from Brocchi's 

 description. 



The type of Hylodes augusti remained in the possession of Alfred 

 Duges, who had, as Mocquard says, the unhappy idea of sacrificing 

 it for the sake of a prepared skeleton. Mocquard mentions a young 

 individual from Guanajuato that he had received from Dug^s. This 

 specimen (M.H.N. P. No. 508q!, parchment label No. 99-291) has a 

 head-and-body length of 20 mm.; the hind limb being carried forward 

 along the body, the tibio-tarsal joint reaches the middle of the eye; 

 a broad transverse pink or pale yellow band with several dark spots 

 crosses the back behind the level of the fore limbs; and the hind 

 limbs have dark transverse bars. Differences in coloration alone 

 distinguish it from adults of this species. 



Six specimens (M.H.N. P. No. 508jS, parchment labels Nos. 98-260, 

 98-261, 98-262; No. 5O87, parchment labels Nos. 98-263; 98-264; 

 98-265), collected by Leon Diguet at the commencement of the rainy 

 season on the western slope of Cerro San Juan, territory of Tepic
