scales are much more mucrunate than is the case in other smaller ones, 

 even the ventrals being angulate and bristling. 



Relationships. — As one might expect, the new form is very closely 

 related to the Cuban carinatus. The coloration is the most obvious 

 distinguishing feature, but close examination reveals the fact that 

 the scale above the ear is usually prominent in the Acklins and Crooked 

 Island forms, while in the Cuban lizard it is seldom enlarged at all. 

 The malar scales of the new subspecies are larger also, while the first 

 two pairs are especially well marked and nearly square in shape. The 

 Cuban form has shorter anterior malars. The scales on the upper 

 surfaces of the limbs in the new form seem to be slightly smaller and 

 less continuously keeled than in the Cuban lizard, although this feature 

 is very difficult to express by scale counts. The similarities of the two 

 forms outweigh these minor differences, and it is perferable to bestow 

 only a trinomial on the new lizard until further study can be made of 

 the typical carinatus from Cuba.

Since Garman concluded that the lizards from Inagua Island were 

 identical with those from Hispaniola described by Gravenhorst as 

 Pristinotiis sclireibersii, no fresh material had come under the ob- 

 servation of a student of West Indian herpetology until Dr. Bartsch 

 brought back a large and well-preserved collection of Leiocephali 

 from Inagua, an examination of which left no doubt whatever that the 

 species merits full recognition and separation from the neighboring 

 forms found on Hispaniola, Cuba, and the Bahama Islands. 



Diagnosis. — A distinct lateral fold ; four scales (an internasal and 

 three prefrontals) between the rostral and the supraorbital ring; the 

 second prefrontal large and in contact with its fellow ; body scales
