Plcurodona pusilla (Ruthven)^'\ — Santa Maria to Bolivar; Gaira ; 

 Fundacion ; Fonseca ; Arroyo de Arenas. Found about ponds and marshes 

 at the west end of the range and about pools in the low forest at Fundacion, 

 on the bank of the Rio Rancheria at Fonseca, and under rocks near pools 

 in the bed of the Rio Barbacoa at Arroyo de Arenas. 



Dr. Boulenger has {in litt.) referred the specimens described as Palu- 

 dicola pusilla to Paludicola. It certainly does not belong" to this genus as 

 restricted by Mehely,^'^ but is nearer to Pleurodema as defined by that author. 

 The sternum has a long style terminated by a small, slightly cleft 

 xiphisternum. 



Leptodactylus typhonius (Daudin). — Fundacion. Generally distributed, 

 occurring in the clearings, about the open marshes, and in the low forest. 

 During the day found under logs and fallen leaves, but active at night and 

 easily taken in numbers by the aid of a headlight. 



The specimens show two types of coloration, some having regularly 

 arranged transverse spots, others a broad, pale vertebral stripe. 



Leptodactylus pentadactylns (Laurenti). — Fundacion; A'alencia; 

 Arroyo de Arenas; Don Diego (M. A. Carriker). Generally distributed 

 at Fundacion, being found under logs during the day and by headlighting 

 at night. At Valencia observed both in the forest and on the savanna, in 

 the latter habitat under logs. Taken at Arroyo de Arenas under stones at 

 pools in the bed of the Rio Barbacoa, and at Don Diego in the forest. 



The specimens have been identified by Dr. Boulenger. 



Leptodactylus holk'ianus Boulenger. — Santa Alarta to Bolivar; Fun- 

 dacion ; Valle de Upar ; Don Diego. On the banks of streams and ditches. 

 Specimens were found under logs and in dense grass during the day and 

 by headlighting at night, the species being active at night. 



The material has been compared with the type by Miss Joan Procter. 

 It may be noted here that the writer cannot separate the Santa, Marta speci- 

 mens from paratypes of Leptodactylus insulanim Barbour^^ from Saboga 

 Island in the Bay of Panama. , 



Bupemphix pustulosiis (Cope). — Santa Marta to 2,200 feet; Fundacion; 

 Valencia; Don Diego. On the desert at Santa Marta found about the 

 ditches and marshes, and on the lower slope of San Lorenzo near streams 

 in the wooded ravines. At Fundacion found about the forest pools and 

 under logs in the clearings and about the grass marshes. The Valencia 

 specimens were taken in the flood-plain forest and under logs on the 

 savanna. The Don Diego specimens were collected in the low forest. This 

 species has the form of sternum described for E. nattcri by Mehely.^^ 



Bufo murimts (Linnjeus). — Santa Marta to 4,500 feet; Gaira; Funda- 

 cion; Loma Larga (observed). This species doubtless occurs in all locali- 

 ties about the mountains. On San Lorenzo it apparently does not breed 

 above 2,200 feet, although it is not rare between 2,200 feet and 4,500 feet.
