IGUANME.

Aeolis envied Merrem.

One from Utuado, 405 min. in total length. Color in life with iris brown ish yellow, a ring of pure yellow next to the black pupil. Scales around eye yellow, barred with black. These colors seem to hold even when the animal changes color from black to green and yellow. In alcohol the color is largely uniform bluish above and paler below. Pale crescent below eye.

Known to the natives as "the devil." They are afraid of this species and believe that it is deadly poisonous. Mr. Silvester informs me it is rare and occurs along water-courses. He saw another example along the main course of the Arecibo River at Utuado, but was unable to capture it.

Aeolis mayeri sp. nor. Figure 4.

Description.—Body long, rather robust, with slight dorso-nuchal fold. Head rather level on top, with broad median depression on prefrontal region. Slight median depression on occipital region. Eyelids granular. Teeth mod erately large, and become enlarged posteriorly or below eye, those in front of each jaw small. Dewlap moderate, covered with small imbricated scales. Interorbital slightly convex. Ear-opening circular, deep.

Scales all smooth, rather large. Median or vertebral row of scales down back slightly enlarged, and progressing down sides scales become granular on latter. Very minute granules seen scattered about between scales of back, though not visible to the naked eye and not preventing their imbrication on one or more sides in most cases. Scales on belly larger than most scales on back, and small on under surface of head. Scales on head above rather large and smooth. Supraoculars large, flat, and separated from supraorbital semicircles by narrow, complete row of small scales. Supraorbital semicircles with one or two median plates in contact, and separated from occipital plate by one or two rows of scales. Occipital large, nearly equals ear-opening, and scales around variably large and small. Counting vertically, six rows of loreal scales present, and of more or less uniform size. Six or seven large infraorbitals, last ending well before hind edge of eye. Temporals moderate, and about 12 scales between hind eye-edge and ear.

Limbs rather robust. Scales on upper sides of fore-limbs larger than those on middle of back, slightly keeled, and closely imbricated. Scales along lower front femoral region larger than those on belly, smooth and closely imbricated. Scales on upper surface of femur very small and imbricated.

Post-anal plate moderate.

Tail strongly compressed, largely with slight crest. Scales covering sides of tail flat, keeled, those in crest longest and enlarged, a keel forming front edge of each.

Color largely uniform brownish in alcohol, paler below. Some very obscure markings on back, upper surfaces of limbs and tail. Slight pale streak from eye through ear and backward. Another from over shoulder and backward.

Total length 188 mm. (caudal tip damaged) and length from snout tip to vent 67 mm.

Type No. 3151, Princeton University, and 7 paratypes. Virgin Islands.

These examples suggest in many ways that they may be the young of Anolis cuvieri. They agree partly in having the scales of the back in places slightly separated from one another by the interpolating of more or less scat tered, inconspicuous, and irregular small or minute granules, though these in no way encircle the scales. In general the scales of the back present an imbricated appearance. I have for these reasons allowed the species to stand near Anolis cut Teri. Its differences are, however, slight, and as the young of Anolis cuvieri is unknown, I first thought it to be such, especially as all my examples are comparatively small. It would appear too great a latitude in variation to admit such characters as these specimens present as simply variations due to age. First is the contact of several pairs of the large scutes of the supraorbital semicircles, rarely separated by a single row of very small scales. Second, the occipital scale is distinct and usually large, though often separated by only one scale from the supraorbital semicircles. The labials are in contact with the infraorbital semicircle, a character constant in every specimen. In agreement with Anolis cuvieri are the rows of large scales between the rictus and the ear, which vary from 5 to 8. This character will readily serve to distinguish it from the common Anolis cris' tatellt&s. The present new form presents a considerable resemblance to Anolis monensis Stejneger (known only from Mona Island) in the larger scales and rather uniform coloration, though it has small post-rictal scales like its near ally Anolis cristataus.
