SCHMIDT, THE HERPETOLOQY OF PORTO RICO 189 



As in A. stridulus, the scale between the supraciliaries and the supra- 

 orbital semicircles, anterior to the supraorbital granules, is remarkably 

 constant. It is double on one side in only one specimen out of thirty-one 

 examined. The semicircles may be broadly in contact (3 specimens), 

 narrowly in contact (9), or separated by a single row of scales (19). The 

 scales between the semicircles and the occipital vary from two to four. 



Anolis mayeri from the Virgin Islands was compared in the original 

 description with Anolis cuvieri and Anolis cristatellus (Fowler, 1918, 

 Papers Dept. Marine Biol., Carnegie Inst., XII, p. 8, Fig. 4), chiefly 

 because of the presence of small granular scales interspersed between the 

 larger dorsal scales. On examination with sufficient magnification, both 

 A. cristatellus and A. evermwnni prove to exhibit this character. A. 

 mayeri is therefore not particularly related to A. cuvieri and is in fact 

 intermediate between A. cristatellus and .4. evermanni, having the two 

 scales bordering the supraocular granules anteriorly of A. cristatellus, 

 while it is closely allied to .4. evermanni by its habitus (especially the 

 form of the head and tail), the larger scales, and the uniform (green) 

 coloration. It is remarkable that no other specimens of this species have 

 appeared in the numerous collections from the Virgin Islands. 



The results of the examination of the contents of twenty stomachs are 

 as follows: Empty, 3; beetle remains, 11; wasps, 2; ants, 1; caterpillars, 

 1; spiders, 1; skin of Anolis (doubtless its own), 2; juvenile Anolis 

 evermanni, 1. 



Anolis pulchellus Dumeril and Bibron 



The following localities are represented by eighty-seven specimens in 

 the collection: Aibonito, Cata.no, Coamo Springs, Ensenada, Maricao, 

 Mayaguez, San Turce, Culebra and Vieques Islands. 



Anolis pulchellus is recorded from nearly all of the Virgin Islands, in- 

 cluding Anegada and St. Croix. Except for its absence from Mona Island, 

 it has therefore the same distribution as Anolis cristatellus. 



The number of loreal scales in a vertical row is usually four (five or 

 six in A. brugi) ; in eighty-five specimens, sixty-nine have four loreal 

 rows, fifteen have five, and one has six. The scales separating the occipital 

 from the supraorbital semicircles number one in one specimen, two in 

 twenty-nine specimens, three in fifty-one, and four in four. The semi- 

 circles are in contact in seventeen specimens, separated by one scale row 

 in sixty-six, and by two scale rows in two. 



Stejneger supposed that Anolis pulchellus was confined to the coastal 

 plain area, rarely going above five hundred feet in altitude. In the course
