plates, pale, tail, contact and supraocular

TEIIDAL Ameiva end (Cope).

Six from Utuado, Porto Rico, some showing the granules extending forward to the second chin-shield. In one an accessory scale is interpolated between the preparietals and in contact with the parietal.

One from the Arecibo River near the 70-kilometer post, on June 14.

One from a small settlement on the Rio Grande 2 miles from Arecibo, on June 14. It shows two very large plates on the inner tibial surfaces.

Among 13 examples from the Virgin Islands, one shows the prefrontals separated by a small accessory scale, and another has the same scale and frontal divided into three equal scales, two of which are in front as a pair; 3 more examples from the Virgin Islands show the occipital plates rounded and subequal; one also shows an additional plate bordering the third and fourth supralabials and interposed between the loreal, first subocular, and preocular.

Ameiva wetmorel Stejneger. Frontispiece and Figure & Description.—Body elongate, rather slender. Tail long, conic. Head conic, muzzle long. Eyelids granular. Teeth rather large, conic, in one row, and becoming larger as they progress backward. Interorbital level. Ear about size of eye, and tympanum not deep. Hind foot about two-thirds combined length of head and trunk.

Front nasal plates meet rather narrowly in contact on top of snout. Nos tril in suture between two nasals. Supraocular plates three, in contact with prefrontal, frontal, fronto-parietal, and parietal. Fronto-parietals united as a single plate before 3 large parietals, of which median is much narrowest. Suboculars narrow, first two each half length of last. Loreal in contact with second and third labials, first three suboculars, first supra-preocular, prefrontal, fronto-nasal, and hind nasal. First supraocular in contact with first superciliary, loreal, prefrontal, frontal, and second supraocular. Second and third supraoculars separated from superciliaries by a narrow series of very small scales. Second supraocular in contact with first supraocular, frontal, fronto-parietal, and third supraocular. Third supraocular in contact with second, fronto-parietal, and parietal. Superciliaries of five plates, last small, about equal and all combined only equal in length to anterior one. A row of narrow occipital plates. Six superior and 5 inferior labials to rictus. Ear-opening not denticulated. First pair of chin-shields in contact, second pair separated only in front by narrow single row of small granules. Three rows of scales on gular fold, front and hind rows of about equal width, median row larger. Scales on upper surface of body and limbs minute. Brachium

with one series of very broad plates externally and a narrower inner series. Antebrachium with three series of small plates. On under surface of tibia two rows of enlarged plates, outer row of much larger plates, and one above enormously enlarged. Eight rows of abdominal plates. Three large anals, one in front and two behind. Tail covered with rings of smooth scales.

Color in alcohol largely black above, with 7 longitudinal sharply defined narrow lines of very pale blue-green, distributed as follows: Median, much broader than the others, extends from tip of snout to tail, where it broadens out and, like the others, fades in the more bluish color of the tail. A second streak includes the superciliaries and extends back on upper side of head till above shoulder. On each side, from lower edge of eye back over ear, along its upper edge, a narrow pale blue-green line extends back alongside of tail, fading out behind. Another similar line is on each side from lower ear-edge above shoulder back to groin; below this another still narrower line of same color from axillary to groin. Behind hind leg a single pale blue-green line extends back alongside of tail, fading out behind and much wider than lines ending in groin. Upper surface of limbs blackish like back, each forearm with lengthwise median pale blue-green line, broken in one or more places, and continued up on upper arm as several spots. Several pale spots on outer surfaces of limb in black field. Upper surfaces of hind limb conspicuously spotted with pale blue-green. Under surface of body mostly uniform pale blue-green. Feet and hands dark above, pale below. Tail largely pale bluish, especially terminally.

Color in life with tail greenish-blue (coppery-blue), ground-color above black and below pinkish gray. Dorsal median longitudinal stripe, and three lateral longitudinal stripes, deep straw-yellow. Shorter stripes begin at both nostrils and extend to groin. Legs spotted yellow on brownish-black ground color.

Total length 103 mm., from snout tip to vent 31 mm.

One example from Ensenada, Porto Rico, June 1, 1915. Collected by Mr. M. H. Sanborn.

The above is the only example I have seen, though several others have been reported. Its striking coloration will at once distinguish it from the well known Ameiva exul. Apparently not reported since described.'
