striatus: Hispaniola; Île de la Gonâve; Isla Saona; intergrades with E. s. exagistus. Type locality: Santo Domingo and St. Thomas; restricted by Sheplan and Schwartz, 1974, to the city of Santo Domingo, Distrito Nacional, República Dominicana.

exagistus: Hispaniola: Haiti, distal portion of the Tiburon Peninsula, east to Les Basses, but presumably occurring further east. Type locality: Camp Perrin, Departement du Sud, Haiti.

warreni: Île de la Tortue; Type locality: Vicinity of Palmiste, lIe de la Tortue, Haiti.  
TypesSyntypes: lost, formerly in ZMH, now destroyed.
Holotype: MCZ 125603, adult female [exagistus]
Holotype: MCZ 125604, adult female [warreni] 
DiagnosisDESCRIPTION: Maximum SVL 2330 mm; dorsal scale rows on neck 34-49, at midbody 35-65; ventrals 270-299 in males, 266-298 in females; subcaudals 76-102 in males, 76-94 in females; ventrals + subcaudals 353-390 in males, 343-387 in females; head scale formula 3/5-1/2-5. Body blotches 60-122, but dorsum often virtually patternless or with blotches so fused as to be uncountable; blotches, rhombs, or spots gray, tan, or brown, outlined or not by dark brown to black on paler brown, gray, or red-brown ground; blotches more or less subcircular, ovate to angulate, often modified, by alternation, into chain-like pattern, saddles, or bands; usually a secondary series of smaller angulate blotches on lower sides, lying at apices of primary dorsal blotches; lateral neck stripe may be very prominent, extending anterior third of body in some specimens, but weakly developed in others; upper side of tail with 0-28 blotches, but may be solid dark brown to black; venter cream, gray, or brown, with scattered to regular dark brown to dark gray markings forming longitudinal short lines, line segments, or rectangular blotches (Schwartz & Henderson 1991: 609).
