In Imetiana the nasal has either replaced the loreal by being extended backward to contact the preoeular, or has fused with the loreal. Of the diagnostic characters used by Cochran (1941) in her description of Dorlingtonia liaetiana, only two set this species apart from the other members of the present species assemblage. These are: tlie single anal plate in contrast to the divided plate of the other species; and the first pair of lower labials not meeting in the midvcntral line. In view of the scale variations already noted for this group, these characters are only doubtfully of generic value in this assemblage. With respect to scale pits, funereus and polylcpis haw two pits per dorsal body scale, calUlaemus has only one. The pit in the latter is asymmetrical and suggests its derivation from a two-pit condition by the loss of one pit. The Cuban species lack scale pits, as does haetiana. On Puerto' Rico exiguiis stahli has no pits on most of the body scales, but may have two pits on the scales of the dorsal side of the neck. The subspecies exiguus exiguus has no.
