to the fauna, two l)eing descril)ed as new species. The additions, in 

 Professor Peters's nomenclature, are as follows: 



1. Aii(>Jl>< (jimdlachi. 



2. A^iolls hrugi. 



3. AiiK'ini plei. 



4. Aii}2>}i/xhs^na caeca.

6. Ilylodcx 1)1(1 rfhurenfiis. 



Total niinihcr of species known in 1S76 conscxjuentl}" was twenty-two. 



The sul)stance of Dr. Peters's paper was rei)ul>lished in ISSl by Dr. 

 Gundlach in tiie Anales de la Sociedad Espaiiola de Histona Natural 

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

 namely, the marine turtles ClicJoiiia n!r!dl)< and Cdirtta htihr/cata^ 

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



Dr. Ao-ostm Stahl, the venerable patriot and naturalist of F)ayamon, 

 Porto Kico, in 18S2 pu])lished a Fauna de Puerto-Kico. intended 

 mainly as a catalogue of his laroe collections, but with bii(>f indica- 

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

 re])tiles he omits two species, namcdy. ]\f((hin/<i shnui!/ M\d Ifenudac- 

 t(/h(s nidhoiild^ thouo'h the latter is indicated without name, but a 

 marine turtle is added, namel}" Clx/Jonin cdrdtd^ thus increasing- the 

 number of species known to tvventy-tive. 



In 1896 Dr. Boulanger, the celel)rated ht'rpetoloo-ist and icthyologist 

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

 from Mona Island (h^posited in the museum at Magdel)urii-, (lermany, 

 by Mr. H. Boettcher. It contained but three species, ()ut the Ainelra 

 turned out to be an undesci'ibed species which Dr. lioulanuci- named 

 A. (ilhoguttdtd., raising- the munber of species to twenty-six. 



The twenty-seventh species also comes from Mona Island, beinoa])oid 

 snake, Epicr(ifr.'< nionensts^ described in 181*8 from four specimens in the 

 museum at Hamburg, Germany , ])y Dr. Zenni^ck. These specimens were 

 collected on Mona Island during 181)1 and 181>-1: by Mr. CUi. Bock, who, 

 at that time, sent the Hambui-gnmseum a large munber of specimens of 

 other species from this interesting little island. These were reported 

 u})on by Mr. Meerwarth in 11N)1, who thus was able to add three species, 

 two of which he described as new forms, namely IlyJodcs inonensu and 

 S2>fKvrodactyh(s nuicrolt'ph monensis^ the third being MiiopMX-efOH cornu- 

 tit.s., 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." 



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 iin})ortant contributions to the 

 West Indian herpetology pubhslied )jy Prof. S. Garnian there are fre(juent references 

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

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