deep at Rongelap Atoll, whereas at Guam it occurred in the intertidal 

 zone of the reef. 



Remarks. — Randall (Copeia, No. 3, p. 237, 1955), on the basis of 

 his study of specimens in the U. S. National Museum, finds that 

 Bleeker's "renardi" represents the adult male of strigiventer. I 

 agree with his observations and interpretations. This is another 

 example of sexual dichromatism in reef fishes observable only when 

 large series of well preserved specimens are available.
