MEXICAN TAILLESS AMPHIBIANS 143 



faint; adhesive disks of fingers slightly larger than those of 

 toes and often larger than tympanum; the hind limb being 

 carried forward along the body, the tibio-tarsal joint reaches 

 between eye and tip of the snout; vomerine teeth in two 

 oblique series between anterior margins of choanae, almost in 

 contact medially; fronto-parietal bones not in contact anteri- 

 orly, leaving a small fontanelle; tympanum more than one-half 

 and often three-fourths diameter of eye; tongue broad, notched 

 behind; head broad; canthus rostralis obtuse; loreal region 

 concave, oblique; skin of back smooth, with a few scattered 

 small warts; top of head shagreened between tympani; under- 

 parts, with exception of gular region, coarsely granulated; upper- 

 parts (of specimens in alcohol or formalin) green, blue-green, or 

 violet, rarely with round yellow spots; sides often with lateral 

 yellow bands; concealed surfaces of limbs, hands, and feet 

 yellowish, with exception of outer finger and toe, which are 

 same color as back; a white line along outer edge of forearm, 

 lower hind limb, and tarsus; under surfaces white; male with 

 single subgular sac; head-and-body length, 58 to 77 mm.

PHYLLOMEDUSA DACNICOLOR Cope 



1864. Phyllomedusa dacnicolor Cope, Proc. Acad. Nat. Sci. Philadelphia, vol. 

 16, p. 181, Aug. 



Type locality. — Near Colima, State of Colima, Mexico. 



Range. — West of the Mexican Plateau, from southern Sinaloa to 

 the southern boundary of Guerrero. 



Remarks. — The type of this species, which can not now be located, 

 was evidently collected by John Xantus de Vesey, for Cope states 

 that it was removed "from the large Xantusian Coll." Several living 

 individuals of this species collected near the Presidio in Sinaloa were 

 brought to London by Alphonso Forrer. In describing these frogs 

 Boulenger ^^ remarks that large individuals may have a head-and- 

 body length of 83 mm. and in addition makes the following comments: 



The faculty of opposing the inner finger and toe is conspicuous, though less so 

 than in the typical species of Phyllomedusa. The colour of the upper parts is 

 normally bright green, but rapidly changes to olive or brown; white dots are 

 scattered on the flanks; the lower parts are pure white; the two inner fingers, the 

 three inner toes, the lower surface of the hands and feet, and the sides of the limbs 

 are yellowish pink. The iris is black, vermiculated with gold; a golden line borders 

 the vertical pupil. The nictitating lid is veined with gold, and the lower eyelid 

 completely opaque, green. 



Entries made in the field catalogues of Nelson and Goldman show 

 that two of these frogs (U.S.N. M. Nos. 46954-55), taken on June 30, 

 1897, in green grass on a plain near Acaponeta in Nayarit, were bright 

 green on the back, and another individual (No. 46950) caught in a 

 public garden in the middle of the city of Rosario, Sinaloa, on July 6,
