Six specimens, 74-144 mm. long, vary in the relative 

 lengths of their rostrums. In three, the distance from the 

 eye to the tip of the snout is almost equal to, or shorter than 

 that from the eye to the ventral fins ; the others have the 

 rostrum longer, it being equal to, or a little less than the 

 length from the eye to the vent. A Western Australian 

 specimen is also much more rugose than the others, but does 

 not otherwise differ from them. 



They also exhibit some variation in the development of 

 the lateral spines of the tail. In younger specimens the last 

 three segments are armed with spines directed backwards 

 and forwards ; these disappear with age, becoming involved 

 in the general anchylosis which occurs in the posterior rings.
