by peofessor f. w. huttox. 69 The Fishes of the Palmer Eiyer. By William Macleay, P.L.S., &c. Tlie Hevd. J. E. Tenison-Woods procured while at the Pahuer E-iver, in !N^orthern Queensland, a small collection of the Fishes of that river, which he has asked me to examine and if necessary to describe. He is indebted to Mr. Selheim, a G-erman naturalist resident in the Palmer District, for the greater number of them.

Therapon" fasciatus, Casteln. Proc. Linn. Soc, N. S. Wales, Vol. 5, p. 363. This species seems to be confined to the rivers flowing into the Grulf of Carpentaria. A similarly marked, though very distinct species — Therapon percoides, Gunth. — is found in the East Coast rivers of Queensland.

I described this fish originally from a specimen sent me from the Endeavour River. It is easily recognizable from T. unicolor and other unicolorous species, by the broad head, fleshy lips and smooth preorbital bones. 3. Eleotris plaxiceps, Qi. sp. D. 6/10. A. 8. Head broad, flat, and one third of the total length ; mouth large and flat, the lower jaw protruding, the maxillary reaching to below the middle of the eye. The eye rather small and more than three diameters apart. The scales on the body are rather large and finely ciliated, those on the head smaller, and on the fore part of the head between the eyes there are a number of small
