STUDIES IN AUSTRALIAN FISHES — MCCULLOCH. 389 



from Samoa and Identified by them as both 8. guamensie and 

 S. scahra, seems to me to agree very well with Gunther's figure 

 of the former Bpecies. 



They differ from S. scaber in the arrangement of the spines on 



top of the head and in colt mration. In all of my series, including 

 specimens 30-115 nun. long, the infraorbital ridges do nol termi- 

 nate in sharp spines, the occipital spines arise on the same level 

 as, or in from of the end of the postocnlar spines, and there is 

 only rarely one or two small spines between the latter. The 

 general colour is brown with striking darker bars and spots on 

 the head, body and tins, and there is a more or less distinct 

 black spot on the operculum. 



The specimens examined were obtained at the following 



localities : — Samoa, New Hebrides, Lord Howe Island, 

 Tongatabu. Bogainville Island, Duke of York [gland, and 

 Murray Island, Torres Strait.
