AMniiiuANS AND REPTILES OF Santa Marta 63 



de Upar; Badillo; Fonseca; Loma Larga; Arroyo de Arenas Riohacha; 

 Palomina and La Concepcion (W. W. Brown) ; Don Diego (M. A. Carri- 

 ker). Common on the lowlands all about the range, preferring open habi- 

 tats, but not uncommon in the more open parts of the flood-plain forests at 

 Valencia and Valle de Upar. Although a ground form, it readily climbs 

 about in low bushes in search of food. 



Leposoma dispar Peters. — Bolivar to 600 feet; Las Pavas ; Tucurinca 

 (Rehn and Hebard). Found among leaves in the dry forest, except that 

 two specimens were in damp leaves in a marshy plaice on the bank of the 

 Tamocal River. 



Loxopholis nigiccps Cope. — Fundacion ; Las Pavas ; Valencia. At Fun- 

 dacion found in some numbers under logs and in the grass about an open 

 marsh and along the river ; at Valencia two specimens found among leaves 

 and under detached bark in the valley forest. 



The males alone have pores, five on each thigh, and usually four, some- 

 times 5, in the prseanal region. The chin shields are constantly one anterior 

 and four pairs, the members of the first two pairs being in contact. The 

 color of the males is richer (the dorsal parts blackish, the under surfaces 

 more or less red), the females being brownish above and whitish below. 



Tretioscincus hifasciatns (Dumeril). — Bolivar to 2,000 feet; Tucurinca 

 ( Rehn and Hebard) ; Fundacion ; Las Pavas ; Valencia ; Valle de Upar ; 

 Fonseca ; ArroyO' de Arenas ; Don Diego. A common form both in the dry 

 and valley forests. Found among fallen leaves, on and in logs, and on 

 the trees. 



In many specimens the color of the tail is a brilliant blue. 



Bachia hicolor (Cope). — Bolivar to 600 feet; Tucurinca (Rehn and 

 Hebard) ; Loma Larga; Palomina (W. W. Brown). Under logs and rocks 

 in the dry forest. 



There are two species of Bachia in the Santa Marta Mountains region, 

 one of which is the same as Heterodonium bicolor. The specimens taken 

 in the localities given above have the scales in 28 (29) annuli. and have 

 from 44 to 46 scales between the occiput and the tail. The hind limbs are 

 undivided and are decidedly larger than in the specimens which have been 

 referred to the following form. There are four digital tubercles on the 

 fore limbs in all specimens. It is possible that this species is synonymous 

 with B. flavcscens, but if so the definition of the latter must be changed, for 

 the Santa Marta Mountains specimens have fewer scales than given by 

 Boulenger for Havescens, and the dorsal scales are distinctly imbricate. 



Bachia dorbignyi (Dumeril and Bibron). — Valencia; Valle de Upar; 

 Fonseca. Found under logs in the dry forest at Fonseca and in dry parts 

 of the flood-plain forests at Valle de Upar and Valencia. The species is a 

 very active one. 



The specimens referred to this species resemble those identified as B. 

 bicolor, but dififer in having the scales in 26 annuli, in having 46 to 48 scales 

 from the occiput to the base of the tail, in having the hind limb more 

 reduced, and in having but three digital tubercles on the fore limbs. It will
