 of eye 5, interorbital width 4. Dorsal V, 45. Anal 39. Pelvics only reaching four-

Length of the type, 168 mm. to base of caudal. This species is known to me only 

 from Dr PAPPENHEIM'S description and from some notes and measurements that he has 

 kindly sent me. Some of these may be given for comparison with those of the type 

 of C. antarcticus. The measurements are in millimetres.

IV. THE SYSTEMATIC POSITION AND GEOGRAPHICAL DISTRIBUTION OF THE 

 GALAXIID^E AND HAPLOCHITONID.E. 



The Galaxiidse and Haplochitonidae are Teleostean fishes of the order Isospondyli, 

 that is to say, they are malacopterous physostomes with a truly homocercal caudal fin, 

 with abdominal pelvic fins, and with ribs inserted on autogenous parapophyses. In 

 this order the name Salmonoid may be given to a group of fishes with an adipose fin 

 usually present, with one supramaxillary or none, with parietals well developed, and 

 with oviducts absent or incomplete. The relations of the Salmonoid families are 

 indicated in the following synopsis : 



I. An orbitosphenoid ; an opisthotic ; a mesocoracoid ; vertebrae upturned at base 

 of caudal fin ........ 1. Salmonidae. 



II. An orbitosphenoid; no opisthotic; no upturned vertebrae; meso-pterygoids 



toothless. 

 A mesocoracoid ; parapophyses inferior .... 2. Argentinidse. 



No mesocoracoid ; parapophyses lateral . . . S. Microstomidse. 



* The fish named Pagetodes by RICHARDSON (" Erebus " and " Terror" Fish., p. 15, pi. viii. fig. 3) may have belonged 

 to the genus Cryodraco, but in the form of the body, the length of the pelvic fins, and the continuous dorsals it shows 

 more resemblance to Pagetopsis. Until RICHARDSON'S species is rediscovered, the name Pagetodes cannot be used. 



t DOLLO'S figure of the upper surface of the head is enlarged, the length of the head, to the end of the bony 

 operculum, to 80 mm. and the interorbital width to 16 mm.
