Type locality: East Plana Cay, Bahama Islands.  
Reproductionoviparous 
TypesHolotype: MCZ 36711. 
DiagnosisDiagnosis. Allied to Leiocephalus psammodromus but differing in having the second prefrontals in contact with each other and usually larger than in psammodromus. The lateral scales are larger, and the tail is not as strongly compressed. The new form also differs greatly in coloration from its ally [Barbour & Shreve 1935: 358].

Description. Upper head scales large and smooth or very feebly striated; nasal in contact with the rostral; frontals (supraorbitals) in contact; supraoculars six, separated from the frontals by a series of small scales; second prefrontals large and in contact with each other; parietals two pairs in one row; a strong < shaped fold on either side of the neck. Dorsal and caudal crest slightly developed, being but a feebly serrated ridge. Dorsal scales small, broader than long, not or very feebly mucronate, not serrated posteriorly, the keels forming continuous and slightly oblique lines; lateral scales smaller than dorsals; scales back of ear small, almost granular; ventrals as large as or a little larger than dorsals, smooth, rounded and broader than long; about 68 scales from occiput to base of tail (about 68 to 77 in para types), about 62 scales round the middle of the body (about 58 to 69 in paratypes). Tail fairly well compressed (somewhat more compressed in paratype 36,714 than in the rest), the crest somewhat more developed than that on body [Barbour & Shreve 1935: 358]. 
CommentFor illustrations see Rabb, 1957.
