vertebral broader. Ventrals 266 to 271. Subcaudals 36 to 52, entire. 

 Yellowish, reddish, or greyish brown, light to dark, punctulate and 

 clouded with darker, with irregular transverse badly defined bands of 

 darker, which are often confluent into more or less distinct longitudinal 

 bands on the sides of the neck. Belly olivaceous, flecked with lighter. 

 Tail sometimes transversely banded. Some specimens are nearly uni- 

 form in coloration, very light to almost uniform black. The specimens 

 described were large ones from Porto Rico. Reinhardt's specimens had 

 264 to 271 ventrals, and 67 to 69 subcaudals. The tail is shorter in the 

 adult, and commonly the tip is imperfect.
