I include Meerwarth's record of semilineatus from Port-au- 

 Prince with considerable doubt as to its correctness, since in our own 

 copious collection of lizards from Port-au-Prince I have not yet 

 encountered the species. A closer examination might prove Meer- 

 warth's specimens to be olssoni, which is known to occur there. 



Description. — Adult male, U.S.N. M. No. 74868, from Rio San 

 Juan, Dominican Republic, collected in March 1928, by G. S. Miller, 

 Jr. Top of head with two slightly curved low frontal ridges border- 

 ing a very shallow frontal hollow; head scales distinctly keeled and 

 relatively small; six scales in a row between the supranasals; supra- 

 ocular semicircles separated by two rows of scales (in this specimen) ; 

 occipital medium-sized, about equal to the ear opening in size, sepa- 

 rated from the supraocular semicircle by two or three wrinkled scales ;

Figure 44. — Anolis semilineatus: a, Top of head; b, side of head; c, middorsal scales; d, side 

 of tail. U.S.N.M. No. 74868, from Rio San Juan, Dominican Republic. Three times 

 natural size. 



small keeled scales, the former completely separated from the supra- 

 orbital semicircles by a row of small, keeled scales, the latter separated 

 from the superciliaries by about three rows of granular scales; a series 

 of three enlarged and elongated scales bordering the anterior inner 

 portion of the first superciliary; canthus rostralis projecting over the 

 loreal region, composed of four elongate narrow shields, the second 

 and third the longest; superciliary ridge consisting of one very long 

 and narrow anterior shield followed by a shorter one, which is in turn 

 followed by a double row of small elongate scales separating the supra- 

 ocular granules from those surrounding the eye; loreal rows four or 

 five; subocular semicircle composed of about five keeled scales, the 

 second and third much the longest, the third and fourth in contact 

 with the supralabials; seven supralabials, the suture between the 

 fifth and sixth coming below the center of the eye ; temporals minutely 

 granular, with a patch of irregular, larger scales marking off the supra- 

 temporal region; dorsal scales arranged in about 10 longitudinal rows
