cauglit the specimen, to be green in life. In alcohol it is pale brown above, 

 varied -with a few light points, which are more numerous and distinct on 

 the head. There is an indistinct reticulation on the posterior part of the 

 sides. Labial plates dark brown, the lines of their distinguishing sutures 

 in some cases yellow. Inferior surfaces straw color, except gular region, 

 which is pale brown yellow spotted. 



Length to vent, .073 ; do. to line of can thus oris, .013 ; do. to line of 

 posterior borders of auricular meatus, .018 ; do. to axilla3, .035 ; length 

 of anterior limb, .025 ; do. of anterior foot, .010 ; do. of posterior limb, 

 .031 ; do. of postesior foot, .015. The end of the tail is reproduced and so 

 its length cannot be given, but its base is quite robust. No. 13,903. 



This species is nearer to the A. prmsignis Hallow, than the ^1. lar Cope. 

 Both are West Indian in habitat. A fourth species of the genus is de- 

 scribed by Bocourt under the name Idiodactylus georgeensis, in the Miss. 

 Sci. Mexique Reptiles, p. 41, and is handsomely figured, PI. x, fig. 1. It 

 diflFers from the other species according to Bocourt in the absence of the 

 palpebral spine, and from the A. irregularis in the equality of the dorsal 

 scales. It is from the Belize.

Scales in nineteen longitudinal rows, all keeled. Superior labial plates 

 eight, the fourth and fifth below the eye ; the fifth and sixth separated from 

 the parietal by a large temporal, and the seventh separated from the pari- 

 €ntal by a single wide temporal. On one side there are two small scales 

 between these large temporals which are wanting on the other side. 

 Loreal as high as long ; one preocular. Internasals as long as prefrontals. 

 Prefrontal elongate, with concave sides, well separated from preoculars. 

 Parietals elongate. Postgeneials longer than pregeneials. 



Color brownish-olive, with a pale olive lateral band extending along the 

 third and fourth rows of scales. No dorsal band except for a short dis- 

 tance posterior to the nape, and a very faint trace beyond. Head dark 

 brown above, with a pair of light parietal spots. Superior and inferior 

 labial plates and the first three large gastrosteges reddish-orange or sal- 

 mon color. Under surfaces everywhere else pale olive, without markings. 

 When the skin is stretched some light spots appear, which give an Incom- 

 plete outline of a row of quadrate dark spots above the lateral band. No 

 traces of a superior series, although there is space for them. 



Total length, M. .755 ; length to canthus oris, .031 ; of tail, .214. Gas- 

 trosteges .148 ; one anal ; urosteges 92. No. 18,906. 



This species belongs to the K saurita group, but is more robust than the 

 North American species that belong to it. It resembles in coloration and 

 in the keeled first row of scales the E. sackeni of Florida. It differs in the
