Description of a new species of Galaxias from Mount 



AYiLsox, with remarks on the distribution of the Genus. 



By William Macleay, F.L.S., &c. 



Galaxias Coxii, 



B. 7. D. 10. A. 11. y. 7. P. 12. 



Height of body one-sixth, of the total length ; length of head 

 about one-fifth of the same. Head broad and depressed between 

 the eyes. Eyes about one-fifth of the length of the head, and 

 less than haK their diameter distant from the mouth. Mouth 

 large and slightly oblique, the maxillary extending to below the 

 middle of the orbit. Teeth in the jaws in a single row, acute, 

 rather distant and interspersed with a few of larger size ; those on 

 the palate in a series of about seven on each side of a central 

 longitudinal ridge, and those on the tongue in two series of strong, 

 acute, slightly hooked teeth, five or six in number, separated by 

 a very deep longitudinal groove. The pectoral and ventral fins 

 are about the same length, and have a pointed look owing to the 

 middle rays being the longest ; the dorsal and anal are about 

 equally long, the latter commencing opposite the middle of the 

 former ; the caudal is truncated and is rather broad and spreading. 

 The colour in the fresh specimen is greenish olive, spotted all 

 over with dark drown, the spots towards the tail sometimes 

 coalescing so as to look like ''fasciae," the belly is yellowish, 

 there is a large oblong black spot behind the operculum just 

 above the base of the pectoral fin. All the fins are of a beautiful 

 reddish-pink colour tipped with black. 



Three specimens, seven inches long. 



I am indebeted to the Honble. E. K. Cox, M.L.C., for the 

 specimens from which the above description is taken. They were 

 taken by him from a small rivulet on or near the smnmit of 

 Mount Wilson. The height of the mountain is about 3,500 feet
