I have examined three paratypes (USNM 282532-34) and I do not find any differences be- tween these specimens and type material of C. exasperatus. Rivero reported C. parens to have an oblique lateral stripe; however, a close examination of the stripe reveals that it is the same as the dorso- lateral stripe of C. exasperatus. Therefore, I relegate the nominal C. parens (Rivero, 1991b) to the syn- onymy of C. exasperatus (Duellman and Lynch, 1988).
