poral slender, forming the greater part of the supratemporal arch, its an- 

 terior extremity in contact with the postorbital and postorbital process of 

 jugal bones. Paroccipital small ; parietoquadrate arch well developed. 

 Supraoccipital loosely attached, coossifiied with exoccipital. 



The frontal bone is grooved on the median line below. The postoptics 

 are within tlie epipterygoids, and are curved, enclosing a subcircular 

 space, and have a short external branch. The epipterygoid leaves the 

 pterygoid behind tlie ectopterygoid process, and articulates with the pari- 

 etal, passing some distance in front of the petrosal. The petrosal is 

 very short above ; the "subforaminal process is distinct, and the inferior 

 groove looks outwards as well as downwards. Quadrate with wide exter- 

 nal conch and no internal conch. Stapes not deeply sunk ; columella 

 slender. The vomers are flat and elongate, and are not separated by a 

 groove. The palatines are broad and flat, and the maxillopalatine fora- 

 men is small. The pterygoids are broad and flit in front, and are then 

 abruptly contracted from the outside to a narrow posterior part. This 

 curves outwards from the long basipterygoid processes to the quadrate. 

 The ectopterygoids are short and are deflected at the proximal extremity. 

 Presphenoid long and rod-like. Occipital condyle convex, simple, with- 

 out exoccipital divisions. 



The mandible has marked peculiarities. The Meckelian groove is 

 closed, and the splenial bone, if present, is minute. I do not detect it in 

 the A, caroliriensis. There is a fossa on the inside of the ramus at the 

 base of the coronoid. The latter bone is developed much anterior to its 

 apex on the external face, and not posteriorly. The dentary is produced 

 far posterior to the coronoid. The angular and articular are fused, and 

 the angle is rather short and has an internal angular projection 

 (^Xiphocercus valenciennii, Anolis eqiiestris, A. marmoratus, A. carolinen- 

 sis). 



The hyoid apparatus has the extreme development seen in all the lizards 

 with a gular compressed pouch or fan. That is, the ceratobranchials of 

 the second pair are closely appraised and produced to a great length. 

 First pair of ceratobranchials and ceratohyals simple, the latter attached 

 to the extremities of the moderately developed hypohyals. 



The scapular arch conforms to the Iguanid type. There is a proscapula 

 well above the coracoid, and a single coracoid notch. The sternum has 

 a small median fontanelle which is reached by the long posterior limb of 

 the interclavicle. Two ribs attached to each side of sternum, and three to 

 each of the slender, closely appressed xiphoid rods. There are five pairs 

 of abdominal ribs in Anolis carolinensis, and four, five and six in other 

 species. 



The vertebrse have no zyosphen nor elongate diapophj'ses. There are 

 eight cervical vertebrae, of which only the last four have ribs, all of which 

 have simple heads, the last two being elongate and reaching to the plane 

 of the sternum. 



The caudal vertebra; have no supplementary dividing suture, and there
