Page 358 (899). The type of the genus Oj>Mchthys Aid is, according 
to Poey, Murcena anmilata Ahl, which is a species of Pisodontophis. 
Genus 170 must therefore stand as Miirwnopsis Le Sueur, and 170 (5) as 
OpMclithys Ahl.

The two species may stand as 588, L. conger (L.) J. & G. and 588 (6), 
L. caudicula (Beau) J. & G.
