Another had eaten two frogs, Bleutherodactyhis crnentus and Geobatrachus 

 zmlkeri. 



All of the specimens have black annuli in pairs, the number on the 

 body varying from ii to 14. The subcaudals are 44 to 64, the ventrals 186 

 to 200. 



Tantilla longifrontale (Boulenger). — San Lorenzo, 4,000 feet; Palo- 

 mina (W. W. Brown). The San Lorenzo specimen was taken on a rock 

 in a stream. 



Tantilla semicinctum (Dumeril and Bibron). — Valle de Upar; Bonda 

 (a specimen in the Museum of Comparative Zoology, from the H. H. Smith 

 collection). The Valle de Upar specimen was in dry woods. 



Tantilla indanoccphala "(Linnaeus). — Fundacion ; \'alencia. Two 

 specimens taken under logs, one in a swamp, and one in low forest. 



Stenorhina degenhardtii (Berthold). — Valencia; Arroyo de Arenas. 

 Only two specimens taken, both on the ground in dense woods. 



The specimens have the color described as variety A by Boulenger.*- 

 and there is a broad, irregular black band on the median ventral line. 



Micrunis mipartitus (Dumeril and Bibron). — San Lorenzo, 5.000 feet; 

 San Sebastian (W. W. Brown). The single specimen found on San 

 Lorenzo was among leaves in heavy forest. 



The specimens (6) all have more than the maximum number of white 

 rings given by Boulenger,*^ the number being from 69 to 75. 



Micrurus dumerilii (Jan). — Macotama and La Concepcion (five speci- 

 mens collected by W. W. Brown) ; Fundacion (i). The Fundacion speci- 

 men was found under a log on the margin of an open swamp. 



The material is puzzling. The specimens correspond in many ways 

 with the descriptions of Jan and Boulenger, and, as these writers had but 

 one specimen each, it is to be expected that a series, such as is at hand 

 from the Santa Marta region, will reveal variations. The only constant 

 differences observed are in the size of the eye, which is three-fourths, not 

 two-thirds, of its distance from the mouth, and in the relative length of 

 the frontal and parietal scales, the former being shorter than the latter. 

 The Fundacion specimen is in coloration similar to those of Jan and Bou- 

 lenger, and the larger one of Werner.** In the others the black bands are 

 about half as wide as in those mentioned, the laterals are poorly defined 

 and are often, and the middle ones occasionally, interrupted ventrally. 

 This coloration is apparently represented by Werner's smaller specimen. 

 In some specimens from La Concepcion the postnasal is broadly in contact 

 with the preocular, in others the suture is short, and in still others these 

 scales are completely separated. The triads on the body vary from 9 to 14, 

 th^ ventrals are 180-200, and the subcaudals are 31 to 50. 



It is the opinion of the writer that all of these specimens must for the
