1. GALAXIAS. 211 



or one-tenth of the total length (without caudal) ; the length of the 

 head is nearly one-sixth of the total (without caudal). Snout with 

 the jaws equal in length ; cleft of the mouth rather narrow ; the 

 maxillaiy extending to below the anterior margin of the orbit. Eye 

 of moderate size, somewhat shorter than the snout, more than one- 

 fifth of the length of the head. The length of the pectoral is much 

 less than one-half of the distance of its root from the ventral, and 

 that of the ventral is one-third or nearly one-third of the distance 

 of its root from the anal. The least depth of the tail is one-half of 

 the distance between dorsal and caudal fins. Caudal emarginate. 

 Yellowish- oHve, body with numerous faint spots, each spot being 

 composed of minute dots. Operculum silvery.

 parts of South America. 



I have been unable to detect any specific difference in the American 

 and Australian specimens which I have had an opportunity of 

 examining.

6. Galaxias krefftii. 

 D. 12. A. 16. P. 12. V. 7. 

 Body moderately elongate, subcylindrical, its depth in front of 

 the dorsal being contained seven times and one-half in the total 

 length (without caudal) ; the length of the head is contained five 

 times and one-half in the same. Snout broad, with the jaws equal 

 in length ; cleft of the mouth rather narrow ; the maxillary extend- 

 ing nearly to below the front margin of the orbit. Eye of moderate 

 size, as long as the snout, one-fourth of the length of the head. 

 The length of the pectoral is considerably less than one-half of the 

 distance of its root from the ventral ; and that of the ventral is two- 

 fifths of the distance of its root from the anal. The least depth of 

 the tail is one-half of the distance between dorsal and caudal fins. 

 Caudal truncate. Yellowish- olive (in spirits) ; back powdered with 

 minute black dots. 



New South Wales. 

 a-c. Three and three and a half inches long. Sydney. From Mr. G. 

 Krefft's Collection.

 head comparatively longer.
