NEW AMPHIBIA. 



BY THOMAS BARBOUR. 



Many collections of Neotropical Amphibia have been received 

 during recent years by the Museum of Comparative Zoology, and 

 in these the following new species have appeared. 



Gymnophis clarkii, sp. no v. 



Type. — No. 11047, Museum of Comparative Zoology, from Tela, Honduras. 

 Collected in June, 1925, by Dr. Herbert Clark. 



Diagnosis. — The shortest and thickest species known. Only about seven 

 anterior and five posterior rings without traces of secondary folds. 



Description. — Diameter, 9 mm.; length, 145 mm.; ratio, 16. Complete 

 rings, 105; the 5th ring shows a tendency to a dorsal cleft, and after an interval 

 of the next few rings, well-developed secondary folds appear. These persist, 

 dividing the primary rings dorsally and sometimes almost completely until 

 about six segments from the posterior end of the animal, where they disappear. 

 The vent is nearly terminal. 



Color. — As usual, plumbeous. 



Phyllomedusa nicefori, sp. nov. 



Plate 12, fig. 1, 2. 



Type. — No. 11611, Museum of Comparative Zoology, from Villavicencio, 1 

 Colombia. Collected by the Rev. Brother Niceforo Maria and named for 

 him, 



Diagnosis. — This species belongs with those having the first toe longer than 

 the second; having vomerine teeth; lacking parotoid glands; thus very similar 

 to P. coelestis, from which it differs in having shorter legs and far less developed 

 digital dilatations. 



Description. — Vomerine teeth in two small but very distinct groups opposite 

 the middle of the choanae; form elongate, size medium; snout longer than 

 diameter of eye, sloping; loreal region likewise declivous; interorbital space 

 broader than upper eyelid; tympanum about one-half diameter of eye; fingers 

 entirely free, long, first slightly shorter than second; fourth nearly as long as 

 third; first toe longer than second; discs of fingers and toes small; scarcely a 

 trace of a metatarsal tubercle; the hind limb being carried forward along the 

 body, the tibio-tarsal articulation reaches the anterior border of the eye; skin 

 smooth above, granular beneath, with several large prominent tubercles on 

 each side of the vent; no parotoid glands. 



Color in alcohol. — Exactly similar to that of P. coelestis, blue (green in life) 

 above, lower lip white, the white line extending completely around the forearm 

 insertion and terminating as a cluster of white dots along the edge of the chest; 

 several white sternal spots; throat and chest lavender, fading posteriorly to 

 dirty white, which is the color of the lower belly and inside of limbs; a white 

 glandular line separating the blue from the white along the back of the fore 

 limbs, while on the hind limbs the blue fades into the light color, with several 

 light spots along the boundary area. A few scattered white tubercles along 



1 A town on the Rio Meta in the tropical lowlands east of Bogotd; altitude, 

 452 meters.
