from the nostril to tlie e^'e, back of wliicli it widens, involving the tym- 

 panum, and extends above the arm and along the side, fading out to- 

 wards the groin j it is bordered above by a white margin, following it 

 all the way from the eye ; the upper edge not very clearly defined, espe- 

 cially behind, where it graduates into the blue of the back. The lower 

 edge of the lateral vitta is margined by a distinct narrow white line 

 (fading anterior to the eye into the blue), which margins the dark border 

 of the upper jaw and extends to the insertion of the arm. The edge of 

 the jaw is brown. Posterior to the fore legs the dark lateral stripe has 

 its lower edge indistinct and fading through bluish white into the white 

 of the belly. On each side of the back there is a narrow dark band, 

 commencing opposite the fore-arm and extending to the inguinal region, 

 the two parallel, and about as wide apart as are the orbits; they are 

 margined by an indistinct border of lighter. Above the anus andbound- 

 ing the back posteriorly is a series of six or eight white spots in contact 

 with each other. There are no bands or blotches across the limbs, al- 

 though on the outer edges (when the animal has all the limbs flexed) 

 there is an indistinct brown line separated from the dorsal blue by blu- 

 ish white.

Nature of spec- 

 imen. 



According to Sumichrast this species is found during the winter sea- 

 son in the vicinity of water, and has the habits of Lithodytes. I have 

 found it near the water, in March, near the City of Mexico. It thus re- 

 sembles its allies of North America proper, Hyla regilla and H. picJc- 

 eringii.
