Thus there are 8 fairly wide black stripes on the neck, 10 just behind 

 the arm insertion, and 11 in front of the hindleg, the central (dorsal) 

 ones the narrowest. Arms with three fairly distinct black stripes on 

 upper surface; legs with black vermiculations on upper surface, the 

 posterior aspect of the femur with a pair of narrow black lines separated 

 by the pearl-gray body color. On the base of the tail the stripes of 

 black become the same width as the interspaces of plumbeous-gray, 

 and rapidly become less and less distinct. Throat, chin, and upper 

 and lower labials all immaculate pale olive-buff. 



Variations. — The characters of this species seem to be subject to 

 only a small degree of variation. Even the number of dorsal granules 

 in the standard distance from center of eye to tip of snout is far less

variable than is usually the case among Ameivas. The scalation of 

 the head is practically the same in all the specimens, except in 

 U.S.N.M. No. 77953, where the excessive enlargement of the first 

 superciliary has prevented the contact of the first preocular and the 

 loreal that takes place in the other examples. The fourth supra- 

 ocular is sometimes completely separated by granular scales from the 

 occipital bordering the median one. This is not, however, a character 

 of much significance. Body scalation is quite constant, there being 8 

 transverse rows in every case, while the longitudinal rows are 32 to 

 34. The tail has 17 to 19 plates in the fifteenth verticil. Coloration is 

 as constant as scale arrangement; there are 8 black stripes on the 

 neck and 11 on the sacrum in all specimens. The two examples from 

 Cul-de-Sac Plain have tails dark below and above; in the two from 

 Thomazeau the tails are light below. 



Relationships. — Ameiva lineolata, as well as A. beatensis, appears to 

 be related to A. wetmorei of Puerto Rico. All three species have the 

 first supraocular in contact with the loreal, a character not met with 

 in other Ameivas with oblique supracaudal scales.
