size, 527-1072 mm. long, my specimens prove that the body 

 becomes more elongate with age, the depth being 2.81-3.42 

 respectively in the length from the snout to the hypnral. In the 

 type of H. porosa, which is only 5| inches long, the depth is 2£ 

 in the same length. The latter also has the margins of the 

 preorbital and several opercular bones serrated, while they are 

 nearly smooth in Eurumetopos, though there are distinct indica- 

 tions of serrations in the smallest of my specimens. 



As Enrumetopos, the genus has been defined by Waite (loc. cit.), 

 to whom I am indebted for drawing my attention to its probable 

 identity with Hyper oglyphe.

The type of this species was found on the beach at Bridge- 

 water, Tasmania It was hrought to Sydney by Mr. A. Morton, 

 and while here, a photograph was taken of it which is the original 

 of the very imperfect plate illustrating his paper. An excellent 

 print of it, and a second stuffed specimen 635 mm. long, which 

 was received from him is in the Australian Museum collection. 



Four specimens, 527-1072 mm. long, taken by the "Endeavour " 

 agree perfectly with both the photograph and the skin, but show 

 considerable variation in the depth of the body as noted above. 

 The largest specimen has a rather more tumid snout than the 

 others, and the pectoral fins may be either about three-fourths the 

 length of the head or a little longer than it ; the first anal spine 

 is extremely small, and more or less hidden in the skin. 



Waite has recently described and figured a large example, 

 954 mm. long, from the Chatham Islands, New Zealand. He 

 also had another smaller one, 537 mm. long, from the market in 

 Christchurch, of which a cast is in the Australian Museum. His 

 figure agrees better with my smaller specimens than the larger 

 ones, though in none of mine is the curve of the back so pro- 

 nounced as he shows it. I therefore publish a photograph of a 

 specimen in the flesh, 900 mm. in length. 



H. johnstonii is possibly the adult form of H. porosa, 

 Richardson 1 which is known only from the type specimen, 5^ 

 inches long, and some very small ones 25-30 mm. long which
