372 On a new Fish from Chile. 



LXI. — Description of a new Fish of the Genus Galaxlas 

 from Chile. By C. Tate liEGAN, M.A. 



Galaxias hullocki. 



Depth of body about 5 in the length, length of head 4 to 4^. 

 Snout a little shorter than eye, the diameter of which is 3^ in 

 the length of head and less than the interorbital width. 

 Mouth oblique j jaws equal anteriorly or the lower a little 

 projecting ; maxillary extending to below anterior edge or 

 anterior ^ of eye ; no canine teeth. 6 branchiostegals ; about 

 10 gill-rakers on the lower part of the anterior arch. Dorsal 

 9-11. Anal 13-16. Origin of anal well in advance of that 

 of the dorsal ; posterior end of base of anal vertically below 

 that of the dorsal. Pectoral extending about \ of the 

 distance from its base to that of the ventral. Ventrals 

 5-rayed, originating at a point a little nearer to the end of 

 snout than to the base of caudal. Caudal emarginate. 

 Caudal peduncle much longer than deep. Greenish; a 

 broad orange longitudinal band along the lower half of the 

 side ; fins pale or tinged with orange. 



Hah. Maguehue, Temuco, Southern Chile. 



Numerous examples, measuring up to 60 mm. in total 

 length, received from Mr. D. S. Bullock, who obtained them 

 on April 6, 1907, from a pool of muddy water left by a 

 dried-up creek. 



This species differs from all others of the genus in having 

 the origin of the anal fin in advance of that of the dorsal and 

 the ventral fins 5-rayed. 



In my " Revision of the Galaxiidae ^' (Proc. Zool. Soc. 

 1905, ii. p. 363) six South-American species of Galaxias 

 were recognized as valid. The only one since described, 

 G. titcombi, Everm. & Kendall (Proc. U.S. Nat. Mus. xxxi. 

 1907, p. 92, fig.), from the Kio Traful, Argentina, is, in my 

 opinion, a synonym of G. platei, Stdr.
