kahawai (Anipis salar). This fish differs but little except in its proportions 

 from G. (Crinideiis) simjjleXy Rich., and is evidently closely allied to that 

 species which frequents the east coast of Australia. 



11. Chilodactylus sjyectabilis, Hutton (Cat. Fish. N. Z., p. 8), is common 

 near the East Cape, and is called by the natives Ehouhounamu or Nanua.

 among one hundred tarakihi.

I have named this fine species in honour of Sir Robert Douglas, Bart., to 

 whose kind hospitality I was indebted for a pleasant fishing excursion at 

 Ngunguru, which afforded me many novelties. 



During the same visit to Ngunguru I obtained a mutilated fragment of 

 the following fish, which appears to bo well-known locally, but is rarely 

 caught. I am unable to identify it with any described species.
