Amphibians and Reptiles of Santa ^NIarta 57 



three genera have diverged far enough to warrant their separation into 

 different famiHes. 



Phyllomcdusa tarsius (Cope). — Aracataca; Fundacion (observed). 

 Dense woods in flood-plain forest. A single specimen is referred to this 

 species, although it is not typical. The hind limbs are shorter than in the 

 specimens of F. tarsius examined, the heel extending to the middle of the 

 tympanum instead of to the anterior border of the orbit; the parotoids are 

 indistinct, and the white markings around the vent, characteristic of P. 

 tarsiiiSj are lacking. 



Hylella pearsei, new species-'' 



Description: Tongue subcircular, slightly emarginate behind. Head 

 broader than long; snout as long as diameter of orbit; loreal region high, 

 oblique; interorbital space broader than upper eyelid; tympanum indistinct, 

 about one-third the diameter of eye. Fingers webbed at base, first shorter 

 than second; toes two-thirds webbed; disks of fingers and toes well de- 

 veloped, those of fingers larger than tympanum. The hind limb being 

 carried forward, the tibio-tarsal articulation reaches the posterior margin 

 of the eye. Skin smooth above ; belly and an area below the thighs coarsely 

 granular; a dermal fold from axilla to groin. 



Above pale brown with numerous small, round, dark-brown spots, a 

 poorly-defined brown band posterior to the eye, limbs without well-defined 

 markings ; ventral surfaces pale yellow. 



Length, head and body, 14 mm. ; length of head, 5.5 mm. ; width of 

 head, 6 mm. 



Type Specimen: Museum of Zoology, University of Michigan, No. 

 54,639; Fundacion, Santa Marta Mountains, Colombia; August 11, 1913; 

 A. S. Pearse, collector. 



Habitat: Taken in tall grass in an open marsh. 



Remarks: Noble {Bull Amer. Mus. Nat. Hist., XIJI, pp. 441-445) 

 has recently placed one of the species hitherto referred to Hylella (H. buck- 

 leyi Boulenger) with the Leptodactylidae. H. pearsei has the claw-shaped 

 terminal phalanges of the Hylids. 



Sauria 



Gonatodcs fiiscus (Hallowell). — Santa Marta to about 800 feet on San 

 Lorenzo; Fundacion; Aracataca (Rehn and Hebard) ; Las Pavas ; Valen- 

 cia ; Valle de Upar ; f^onseca ; Riohacha. Very common in the desert scrub 

 and dry forest and on walls in towns in the localities given above, apparently 

 less common in the valley forests. Often found in logs, but generally 

 on trees, particularly those which are partly decayed. Eggs laid in decaying 

 wood. 



Gonatodes vittatus (Lichtenstein). — Don Diego (M. A. Carriker) ; 

 Palomina (W. W. Brown) ; Arroyo de Arenas; Fonseca. A very common 

 species on and in logs and on trees in the forests at Arroyo de xA.renas and 

 Fonseca. 



-■"• Named for the collector of the type specimen, Dr. A. S. Pearse.
