Locs. Specimens of C. cristatus are in the Australian 

 Museum from Cooktown, Queensland, and Houtman Abrol-

Family PEGASID.E. 

 Genus ACANTHOPEGASUS, gen. nov. 



Near Parapegasus, Dumeril, but differing in the structure 

 of the ventral fins. These are composed of one spine and 

 three rays, each of which is clearly divided into two halves 

 in its basal portion ; the spine overlies, and is in close con- 

 tact with the first ray. The body is more rugose and spiny 

 than Parapegasus, but similarly constructed.
