The presence of labial pits, the shortest tail of the entire genus and supralabials separated from the eye result in the Cuban boa being the least derived species of the genus
Chilabothrus. The largest individual measured long and was estimated at more than in mass. He also mentioned one large individual kept in captivity by him that had a length of and was collected at the
Zapata Swamp,
Matanzas Province. Rodríguez (1876) commented that the largest specimens are able grow up to long and in diameter. However, on average
C. angulifer reaches in total length.
Coloring Coloration brown with a pattern of staggered dark brown rhombic spots. Dorsal pattern of 42–65 appressed, angulate, dark brown to black markings on a yellowish to yellow-tan ground, but often (western Cuba) without any dark colors in dorsal pattern, and pattern composed of indeterminate number of medium brown to pale tan, much-fused markings; tail patternless above, or with up to 12 darker dorsal markings.
Scalation C. angulifer possesses 53–69
dorsal scale rows at midbody; 272–292
ventral scales in males, 268–290 in females; 45–55
subcaudal scales in males, 46–54 in females; 321–347
ventrals +
subcaudals in males, 316–339 in females;
supralabial scales separated from eye .
C. angulifer is different from most other species of the genus in that the eye is usually completely separated from the supralabials by a row of lorilabials, and the subcaudals are few. ==Behavior==
