with certainty been shown to be a distinct form : hut, as stated above, it is possible 

 that there is more tlian one form of A. porcatus represented in the Baliamas. Whether 

 Anolia fUsticliua lias the distribution given above, is not certain, according to what 

 I have shown above about A. distichns and Ä. distichoides. Some localités for «A. 

 distichus>-> are perhaps due to A. distichoides, as these two species have not been 

 kept separated, if both «»^ere collected before. About two species, Cyclura cylcura and 

 MaJiuio sloaiiii there is doubt as to the correctness of the determination, as well as 

 about Liophis rubeseens. 



2. On the origin of the reptile fauna of the Bahamas. 



The only writer about the reptile fauna of the Bahamas who has tried to 

 analj'^ze it, is Stejneger (18). Since his very excellent paper on this subject was 

 published, some collections af reptiles have been made in the Bahamas which have 

 given a further knowledge about their distribution. For this reason and also because 

 the opinion about some species given by me above to some extent is different from 

 Stejnbger's I will make a few remarks on this question. 



Not taking into consideration the doubtful species, 30 species (one only a local) 

 of reptiles are found in the Bahamas, 22 lizards and 8 snakes. They belong to 10 

 genera, 5 of them lizards, 5 snakès. Of these 30 species no less than 18 are endemic 

 in the Bahamas (15 lizards, 3 snakes), that is three-fifth of the reptile fauna is 

 characteristic of the archipelago. No genus is endemic.
