SNODGRASS AND HELLER 



from the Revillagigedo Archipelago identified by Jordan and McGre- 

 gor as Priacanthus carolinus, and can find no constant difference 

 among the specimens from the 3 localities. 



The length of the preopercular spine varies, in some it reaches 

 the edge of the opercle and in others it does not. In a specimen in 

 the Stanford University collection from Jamaica, 190 mm. long, the 

 spine is short, not reaching the edge of the opercle, while in a speci- 

 men from Bahia 93 mm. in length, the tip of the spine projects be- 

 yond the opercle. The depth also varies, the smaller specimens being 

 the more slender and duplicating the proportions of the Jamaica speci- 

 men (see below). 



Color in life. Bright metallic red, darkening to crimson on back ; 

 head and belly silvery-red ; membrane of spinous dorsal blotched with 

 olive and red; soft dorsal and ventrals red ; anal crimson with faint 

 dusky bars, black-tipped ; pectorals pale red ; lips and snout olive- 

 red; iris red. (Barrington specimen.)
