Pages 965-970 | Published online: 17 Feb 2007
 

Summary

Two captures each of one and three specimens of Neophrynichthys marmoratus Regan 1913, off Chilean waters are reported. Both represent northward extensions of known geographical range. Observations were made in relation with colour pattern. The presence of sutured platelike hypurals on the terminal vertebral half centrum, and the presence of swimbladder are considered together with pectoral fin shape to suggest location of the species into the family Psychrolutidae of the order Acanthopterygii.

Resumen

Se considera la presencia de hipurales en forma de placas soldadas con el centrum vertebral terminal, junto con la presencia de vegiga gaseosa y el diseño de la aleta pectoral, para sugerir la ubicación de ésta especie en la familia Psychrolutidae del orden Acanthopterygii.
