 Royal Society of South Australia in February, 1917, and one collected by Air. E. 

 Le G. Troughton at Kangaroo Is., 1920. Longest specimen 283 mm. 



The young example referred to is 128 mm. in length, it has a distinct median 

 keel on the anterior half of the opercle and all the body and tail ridges are 

 spinigerous. both these features being absent in the adult. Zietz's record of 

 Doi'viclithw: hcfrrosoiiia is based on tliis specimen, his determination being doubt- 

 less influenced liv the facts that in that s])ccies each ring terminates in a spine and 

 the operculum is ridged, as in the young of //. rostratiis.
