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. 1 



AMPHISB^ENID^E. 



Amphisbsena caeca Cuvier. 



One from Guanica. Rings on body 217, on tail 17. Long occipitals more 

 than half length of frontals. Length 130 mm. Collected by Mr. M. H. San- 

 born. 



BOID^E. 

 I'.'pic rates inornatus (Reinhardt). 



One from Guanica, collected by Mr. Sanborn. Ventrals 264, subcaudals 

 75. Indistinct blotches are seen all along the body, numerous and most 

 distinct on hind part of body and tail. Ventrals largely uniform deep dusky 

 brown. Length 1,675 mm. 



CORONELLID^E. 

 Leimadophis stahli Stejneger. 



Two from Guanica, besides one obtained on a coffee plantation in the 

 mountains 5 miles west of Utuado. They show ventrals 154 to 157, subcaudals 

 90 to 92, anals 2, scales transversely on back 19. Length 363 to 382 mm. 



Alsophis portoricensis Reinhardt and Liitken. 



Two from Guanica, collected by Mr. Sanborn. Ventrals 172 to 180, sub- 

 caudals 116 to 118, anals 2, scales transversely over back 17. Length 534 to 

 1,057 mm. 

 Alsophis antillensis (Schlegel). 



Five from the Virgin Islands. They show ventrals 172 to 183, subcaudals 

 124 to 130, anals 2, scales transversely over back 19. Length 368 to 943 mm.
