a brilliant pattern of white spots on the prefrontals and frontals and 

 a large white spot on the occipital ; a white line beginning in front of 

 the first supraocular and continuing backward on the outer edges of 

 the supraoculars to the outer parietals, behind which the line widens 

 and turns to an iridescent olive-green dorsolateral stripe, much invaded 

 by darker pigment until it finally vanishes on the side of the tail ; a 

 similar much interrupted median dorsal line along the crest ; a sepia 

 lateral stripe beginning behind the eye, and widening and gradually 

 losing itself about midbody ; loreal region, lips, and anterior lower 

 surfaces pea-green to sage-green ; a faint sepia mottling on the 

 throat ; the posterior part of the body and under surfaces of hind 

 legs lightening to olive-buff ; some indistinct, transverse, lateroventral 

 bars of pale china-blue, and a few small light spots of the same hue on 

 the upper surfaces of the limbs ; tail with alternate rings of sepia and 

 white, widening distall}'. 



Paratypes. — An excellent series of lizards of all sizes and ages was 

 obtained on Acklins Island, U.S.N.M. nos. 81482-9 from the hills near 

 Cornucopia taken on July 7, 1930, and no. 8148 1 from Jamaica 

 Bay. From Castle Island, just south of Acklins came U.S.N.M. nos. 

 81562-9, taken July 8, 1930. The same form occurs on Crooked Island, 

 for U.S.N.M. nos. 81492-6 were taken there on July 14, 1930. 



Variation. — About the usual amount of variation is seen in the head 

 plates of this new form. The second pair of prefrontals is usually 

 larger than the others, and in broad contact, although sometimes the 

 presence of an unusually large median snout scale prevents much 

 contact. The frontals and supraoculars may be fully separated by a 

 complete series of small scales, or this series may be much reduced and 

 interrupted. As to coloration, the light longitudinal stripes are usually 

 in evidence, while the dark head with the contrasting brillance of the 

 light markings is an almost invariable condition. The females resemble 

 the males in color. The very young ones, however, do not show such 

 a definite pattern. U.S.N.M. nos. 81488 and 81489, respectively 

 36 mm and ^2 mm snout to anus, have the top of the head drab-gray, 

 with small sepia dots scattered uniformly over the head plates. The 

 body likewise is drab-gray, with the light longitudinal lines plainly 

 showing, and the dorsal region and upper limb surfaces are spotted 

 with sepia, like the head. The throats of most of the adults have dark 

 narrow lines converging anteriorly ; in the type this pattern is greatly 

 obscured and interrupted by the numerous very light-colored scales, 

 which tend to form short transverse groups of three or four scales all 

 over the throat and chest regions. One very old male, no. 81481 

 measuring 105 mm, has lost practically all traces of color pattern. Its
