natricid snake, significant characters of the dentition, vertebrae, hemipenis, and scutellation agree with previous immunological data which indicated that Tretanorhinus is a member of the Central American Dipsadidae. The karyotype of Tretanorhinus variabilis supports the view that this genus is not a

Comparisons are made between the new species and all other South American species of the L. dulcis group. The hemipenis

Dunn (1938:417) characterized the Enulius hemipenis as "slightly bifurcate [= bilobed], sulcus forked [= bifurcated] at extreme distal end, no calyces, organ with minute uniform spines

determined if these are really the same in detail as plugs ejected by females, or just an overflow from active glands. However, another explanation is that the diverse structures (ornamentation, plicae, spines, terminal awns) found on the hemipenis are not without a direct function as is believed (Böhme
