so. 7 IIERPETULUGICAL COLLECTIONS— COCHRAN 21 



Color {hi alcohol) . — Drab-gray above, lighter l)cncath ; traces of a 

 clove-brown lateral stripe beginning on the loreal region, continuing 

 behind the eye over the ear to the shoulder region where it intensifies 

 in hue, then widening and gradually fading out posteriorly ; a second 

 clove-brown stripe ])eginning on the malar region, continuing back- 

 ward below the ear, and joining the ui)per stripe in front of the 

 shoulder : upper parts of limbs and base of tail irregularly mottled 

 with large clove-brown blotches ; skin of gular fan lavender-gray, the 

 scales white with a very fine powdering of minute black dots. Eyelid 

 white, the inner edge dark clove-brown. 



Paratypes. — U.S.N.AI. nos. 81344-5 and 81347-50 from Mariguana 

 Cay collected on July 18, 1930; nos. 81351-72 from Betsy Bay, 

 Mariguana Cay, July 18-20, 1930; nos. 81373-5 from Booby Island, 

 east of Alariguana Cay, July 21, 1930. 



Variations. — Like its near relative Anolis Icucophaciis Icucophaeus 

 from Inagua, and its more distant relative A. cristatelliis from Pue'rto 

 Rico and the Virgin Islands, the nev/ subspecies is subject to consider- 

 able variation in the minor details of the head-plate arrangement, as 

 well as in coloration. There may be only four scales between the 

 nostrils, or twice that number. The supraocular disk may be in contact 

 with the supraorbital semicircles, or separated by one or two rows of 

 granules. The occipital may be set ofif from the supraorbital semi- 

 circles by two to four very irregular scales. The median transversely 

 enlarged scales on the snout are often subdivided and scarcely enlarged, 

 and may or may not touch the anterior supraorbitals. The color 

 pattern is often much more distinct than it is in the type, especially in 

 half-grown specimens. On the other hand, it may be obscured by a 

 highly melanistic condition, in which the whole upper surface is 

 suffused with blackish brown, extending even onto the ventral regions. 

 Very rarely the whole body is pale drab. 



Relationships. — The subspecies from Mariguana Island is more 

 closely related to leucophaeus albipalpebralis than to the typical Inaguan 

 leucophaeus, since the first two forms are without the leopard spots 

 so characteristic of the last-named. 



The two previously described forms seem to attain a larger size 

 than the new subspecies, the largest individual of which is only 65 mm 

 long from snout to vent, out of 33 examples. Several of the Inaguan 

 and Turks Island lizards measure at least 70 mm, and appear to be 

 heavier in structure, although the difference here is scarcely measur- 

 able. The Turks Island form is very light in color and does not have 

 the broad dark lateral strij^c which almost always appears on Mari- 

 guanan lizards.
