and light colors abruptly separated on posterior face of femur, which with 

 the abdomen are pale golden below ; gular region faintly greenish ; chin 

 brown, varied. Tail brown, cross-banded near the end. 



Anolis gingivinus. 



Head elongate ; from end of muzzle to auricular opening twice into length 

 from posterior margin ear to posterior face femur. Muzzle rather narrow, 

 end rounded and truncate in profile. Canthus rostralis straight, acute. Lo- 

 real region a little concave, with five (4) rows of scales, its greatest height half 

 frontal width between last scales of canthus rostralis ; latter distance equal 

 from same point to top of rostral plate. Two pronounced frontal ridges not 

 continued on anterior part of muzzle ; concavity pronounced, elongate, en- 

 closing two rows of smooth scales at middle portion, bordered by two large 

 subequal scales in front of last superciliary ; between anterior of these are 

 three rows of scales, of which the median is often large. Posterior scales of 

 canthus rostralis much larger than second. Superciliaries four or five, in con- 

 tact, sometimes nearly separated by a row of granules. Supraorbital disc sepa- 

 rated by only one row of granules from superciliaries. Occipital well devel- 

 oped, surrounded by numerous flat scales, in a strong depression. Symphyse- 

 als large, first infralabial a little smaller, like the second larger than any la- 

 bials, and preceding an infralabial series of oblique scales. Ear equals half eye. 

 A faint nuchal fold ; two rows of larger median dorsal scales, less than bra- 

 chials ; laterals very minute. Ventrals oval, much larger than dorsals or bra- 

 chials, smaller than supraorbitals. Fan elongate, moderately developed. 

 Tail moderate, strongly compressed, with a strong crest of scales, of which 

 every third is larger and the summit of a cross series. Ramus mandibuli in 

 most specimens thickened in a vertical direction, forming a strong inferior 

 ridge. Posterior limbs short. From end of muzzle to ear opening \" 9 /// ; 

 from latter to vent 4 r/ 4 /// ; anterior limb 2 // 1" f \ posterior to heel 1" 7 /// ; 

 foot 2". 



Above greyish or rusty brown, with darker, rather close vermiculations on 

 the sides, which form a dark superior border to a broad pale band from 

 above axilla to groin. This is bordered below by brown, below which are 

 other dark vermiculations. Inferior surfaces, including fan, immaculate. 9 

 is similar, except in the absence of the dark markings not bordering the late- 

 ral band. 



Six specimens from Anguilla Rock, near Trinidad ; presented by W. J. 

 Cooper to the British Museum. 



Anolis citrin ellus. 



Muzzle of medium outline, slightly depressed and rounded at extremity, 

 less than twice as wide between lachrymal angles than loreal height, but 

 twice as long from same point. Canthus rostralis straight, the' posterior 

 scale largest, the fourth under the lateral nostril. Facial ridges not strong, 

 higher than canthus, each with two large scales in front of first and large 

 superciliary, and enclosing three rows of smaller, flat, smooth scales, which 

 are broad as long, the two outer larger than the median. Superciliaries large, 

 four on each side, in contact, nearly separated by a row of minute scales, and 

 separated from the round occipital by three rows of scales. Supraorbital 

 disc touching or not touching supraorbitals, two larger and six smaller, the 

 inner anterior longer than broad, three times the size of second. Five rows 

 of loreals. Three anterior infralabials larger than labials, the anterior less 

 than symphyseal. Auricular opening two-thirds of ocular. Fan elongate, 

 rather closely scaled. Abdominal scales about equal middle interrugal and 

 brachial ; some of the thoracic keeled. Anterior femoral larger, very weakly 

 keeled ; inferior tibials and antebrachials more strongly. Two median dorsal 

 rows larger keeled, much less than abdominals ; other dorsals and laterals 

 minute, but rather coarse and tuberculiform. Tail but moderately com-
