The type of Besnardia gyrinops is 337mm. in total length: this fish is said to be known locally as "Gran sapo de Mar". The form of the pelvic fins in this species is of some interest. These appear to arise from a pocket-like fold of the skin, and in preserved specimens the fins may be com- pletely everted, presenting a normal appearance, or may be withdrawn so that only the tips project through the opening of the pocket. An exactly similar state of affairs is found in the Pediculate fish Chaunax pictus.
