In the Bahamas this species is recorded from several islands, viz. Abaco, 

 Eleuthera, New Providence, Andros and Cat Island. 



Stejneger (18, p. 332) and Baeboue (1, p. 57), both of them have examined 

 specimens from the Bahamas and Cuba, think it rather probable that there is a 

 constant difference between the specimens from the both localities, but they have 

 not had material enough to settle the cj[uestion. Baeboue (p. 57) writes: »In the 

 Cuban specimens the longitudinal rugae of the head are rather more pronounced, 

 and do not appear to involve so many scutes as in the Bahaman spécimens». He 

 has, indeed, not given any further description of the Bahama specimens. I collected 

 several specimens both on New Providence and on Andros: and according to Bae- 

 boue's statement that this species is common on these islands I think it rather 

 probable that it is the same form that we have collected. In order to make it 

 possible for other authors, who perhaps, will get an opportunity to examine Cuban 

 specimens, to compare the two forms, I am giving the foUwing description of the 

 specimens from Andros and New Providence. As I have seen only a few specimens 

 from other localities than the Bahamas, it is impossible for me to form an opinion 

 whether the Bahama variety ought to be referred to a distinct subspecies or not. 



Description of specimens from Andros and New Providence 

 (common on both islands. Fig. 7): Upper head scales keeled. The upper head 

 ridges rather prominent, beginning behind the supraocular region, running forward 

 to between the nostrils, where they are almost in contact with each other. Each 

 ridge involves about ten scales. These two rows of scales are in contact with each 

 other between the nostrils and sometimes also by one scale between the eyes, but 

 at other parts separated from each other by one series of scales. Several small 

 scales on the end of the snout. A few very small scales behind the nasal. One 

 series of scales between the canthus rostralis and the scales forming the ridges. 

 Sometimes, one of these scales with a little stronger keel, than the other ones. This 

 keel is continued on two of the ridge scales, thus forming a slight but rather dist- 

 inct branch from the ridge towards the canthus rostralis. The enlarged supraocular 

 scales separated from the supraorbitals by small scales. Occipital suri'ounded by 

 feebly keeled scales. A slight occipital depression. Canthus rostralis with six keeled
