2. Auchenopterus aysoni, n. sp.

This elegant little fish is one of the blennies, a family fairly well represented in New Zealand waters, Crysticeps australis and Trypterygium nigripenne being close allies. Only one species of the genus is previously known, from the west coast of South America, but it differs in important respects from the specimen under consideration, which was presented to the Museum by Mr. Ayson, Inspector of Fisheries. Unfortunately, the spirit in which it was sent was too strong, so that the scales and many of the lateral pores were destroyed.

The following is a minute description of the fish:—
