HERPETOLOGY. OF PORTO RICO. 559 



to the fauna, two being described as new species. The additions, in 

 Professor Peters's nomenclature, are as follows: 



1. Anolis gundlachi. 



2. Anolis krugi. 



3. Amewaplei. 



4. Amphisbsena caeca. 



5 . Drom icus parvifrons. 



6. Hylodes martinicensis. 



Total number of species known in 1876 consequently was twenty-two. 



The substance of Dr. Peters's paper was republished in 1881 by Dr. 

 Gundlach in the Anales de la Sociedad Espaiiola de Historia Natural 

 in Madrid, translated into Spanish, with the addition of two species, 

 namely, the marine turtles Chelonia viridis and Caretta imbricata, 

 thus bringing the number of species up to twenty-four. 



Dr. Agostin Stahl, the venerable patriot and naturalist of Bayamon, 

 Porto Rico, in 1882 published a Fauna de Puerto-Rico, intended 

 mainly as a catalogue of his large collections, but with brief indica- 

 tions of the characters of some of the species. In his list of the 

 reptiles he omits two species, namely, Mabuya sloanii and Hemidac- 

 tylus mabouia, though the latter is indicated without name, but a 

 marine turtle is added, namely Chelonia caretta, thus increasing the 

 number of species known' to twenty -five. 



In 1896 Dr. Boulanger, the celebrated herpetologist and icthyologist 

 of the British Museum, reported upon a small collection of reptiles 

 from Mona Island deposited in the museum at Magdeburg, Germany, 

 by Mr. H. Boettcher. It contained but three species, but the Ameiva 

 turned out to be an undescribed species which Dr. Boulanger named 

 A. alboguttata, raising the number of species to twenty-six. 



The twenty-seventh species also comes from Mona Island, beingaboid 

 snake, Epicrates monensis, described in 1898 from four specimens in the 

 museum at Hamburg, Germany, by Dr. Zenneck. These specimens were 

 collected on Mona Island during 1891 and 1891 by Mr. Ch. Bock, who, 

 at that time, sent the Hamburg museum a large number of specimens of 

 other species from this interesting little island. These were reported 

 upon by Mr. Meerwarth in 1901, who thus was able to add three species, 

 two of which he described as new forms, namely Hylodes monensis and 

 Sphcerodactyhis rnacrolepis monensis, the third being Metopoceros cmnu- 

 tus, making a total of thirty species for Porto Rico and dependent islands. 



This ends the published records of the batrachians and reptiles in 

 Porto Rico. a 



The present work increases the number of species to thirty-nine, being 

 an addition of nine species. The number of species described as new 



«It should be added, however, that in the various important contributions to the 

 West Indian herpetology published by Prof. S. Garrnan there are frequent references 

 to Porto Rican specimens, but as none of the species so mentioned by him have 

 been additional to the fauna they have not been noticed in the present connection.
