blenniidae: salariinae — schultz and chapman 351 



where an abundance of loose reef-blocks and crevices occurred. It 

 was not encountered in the Lithothamnium ridge area. 



Remarks. — Two forms of this type of fish can be distmguished 

 among specimens from the tropical Indo-Pacific; those from Polynesia, 

 Micronesia, and Melanesia differ from those in the East Indies and 

 Indian Ocean in the following details: The small black dots on the 

 body, pectoral base, so typical of females and somewhat developed in 

 the males of /. periophthalmus (Cuvier and Valenciennes) from the 

 Indian Ocean and western Pacific are completely absent in the form 

 from Oceania, /. paulus: the dashes behind the eye are not united 

 over the top of the head; the opercular spot is not strongly developed; 

 the alternating dark and light bands over upper lip are poorly de- 

 veloped or absent; and the bars on sides range from very strong to 

 nearly absent.
