The three specimens from San Lorenzo, Veracruz (USNM 123513-5), were identified as _Hyla rickardsi_ by Smith (1947:409). The flash colors have faded in preservative, and so are of no aid in identifying these specimens. Two are adult females with snout-vent lengths of 35 and 39 mm. In possessing a relatively large tympanum and barred thighs, and in lacking a dorsolateral stripe they are typical of _loquax_, but in the amount of webbing on the hands and feet, broad tarsal stripe, and narrow anal stripe they are like _rickardsi_. The third specimen, a juvenile, has a snout-vent length of 25 mm. In coloration it resembles the adults; it has more distinct bars on the limbs. On the basis of geography these specimens should be _loquax_, for the closest known record of _rickardsi_ is more than 200 kilometers to the northwest, whereas _loquax_ is known from several localities around San Lorenzo. Shannon and Werler (1955:383) described _Hyla axillamembrana_ from the lower southern slopes of Los Tuxtlas. The unique type is a small male (27 mm. snout-vent). I have examined the type and find no great differences between it and small specimens of _loquax_. It is not possible to determine the color of the thighs, nor was this information given in the description. _Hyla axillamembrana_ is here considered to be a synonym of _Hyla loquax_. =Hyla microcephala martini= Smith _Oaxaca_: Donaji (15); 43 km.

This frog is abundant in the Gulf lowlands of the isthmus, where large breeding congregations were found in grassy ponds on the savannas and in openings in the forest. Most frequently males were calling from grasses and reeds in the ponds; many individuals were perched precariously on thin blades as high as one meter above the water. The call is a series of low squeaks. Individuals found at night were pale yellow above with light brown lines arranged in an irregular pattern on the back, but often forming a cross or an X-shaped mark in the scapular region. There is a brown stripe from the nostril to the eye and thence to the groin. Anteriorly this stripe is bordered above by a thin white or cream-colored line. Numerous small brown flecks are scattered on the back and dorsal surface of the shank. In most specimens there are thin transverse brown bars on the shank. The thighs and undersides of the limbs are golden yellow; the belly and vocal sac are lemon yellow. The iris is yellowish brown. During the day individuals assume a pale reddish tan ground color with darker brown markings. Twenty-five adult males from Alvarado have an average snout-vent length of 24.1 mm. =Hyla picta= Guenther
