wliicli the first and second are brightest. The second dark band 

 is wider than the first and vertebral ; it and the third arc partly 

 divided by a faint white line. Another white line on each side is 

 produced by a series of dark spots on the ends of the gastrosteges. 

 Labial plates black, j'ellow spotted. Head dark brown above, 

 with a pale shade across frontal, and two just behind parietals. 

 Chin and belly yellowish. 



ANOLIS INSIGNIS, Cope, sp. nov. 



Auricular opening half as large as eye. Scales intermediate ; 

 seven rows between orbits; one or two superorbital rows but 

 little larger than the others ; eight rows across middle of muzzle, 

 and six across loreal region at middle. Three large and two small 

 keeled infralabial rows. Scales of arm smooth, of tail striate. 



Fawn-brown, with four double bands of greenish-blue between 

 axilla and tail. Divided between the brown band b}- a yellow 

 band, which widens below and breaks into spots above. A large 

 round greenish-blue spot with brown centre in front of axilla. 



Interorbital and occipital regions deeply concave, the latter 

 bounded posteriorly by two elevated osseous ridges which meet 

 behind at an acute angle. No facial rugai, front flat except a 

 slight median elevation. Muzzle with broad median ridge. Scales 

 of front equal, those of canthus osseous. Postfrontal and zygo- 

 matic arches prominent, rugose. Inferior loreal rows of scales 

 larger than others, nares surrounded by small scales. Fan very 

 largely developed. An elevated crest or dermal fold on the nape- 

 Scales of the sides and back (except some median rows) flat, 

 pavement-like, equal, smooth, one-third the size of the smooth 

 ventrals. Four median dorsal rows subconic, smaller than the 

 ventrals. Tail proximally compressed, covered with equal scales. 

 Limbs stout, the anterior extending four-fifths way to groin; the 

 hinder reaching nearly to the ear. Scales of the limbs small ; 

 dilatations distinct. 



The colors of this Anolis are very elegant. Besides the large 

 spot behind the angle of the mandible, there is a blue one on the 

 angle surrounded by fawn color, and this by yellow. Sides of the 

 temporal region and neck with yellow spots. Bluish of first cross- 

 baud in a coarse netted figure. Top of head fawn color; fan 

 entirely vermilion ; belly bright yellow. Tail with broad blackish 

 anuuli ; limbs with dark crossbars, three on tibia, femur, and 

 forearm ; two ou humerus.
