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:—
|Total length, 5 in.||143|
|Length of head||35|
|Base of 1st dorsal||12|
|Snout to 1st dorsal||10|
|Space of notch in dorsal||8|
|Extension of caudal rays||21|
|Snout to pectoral||23|
|Length of pectoral||27|
|Snout to eye||9|
|Diameter of eye||4|
Fin Formula.—B., 4; D., 3–33; P., 8; V., 3 (but broken and indistinct); A., 10; LL., 22–3–5, interrupted.
Scales very minute.
Body compressed. Height one-quarter of length and one-sixth less than length of head.
Pair of branched tentacles from above the snout, not from the nostril.
Colour uniform light-brown, with four oval translucent spots on the dorsal fin.
Teeth minute on jaws and vorner.
Tail slightly unsymmetrical, and caudal distinctly separate from both dorsal and anal.
Loc. Bay of Islands; collected by Mr. Stephenson.
