' Holotype. 



A. iridescens. The black patch on the caudal 

 peduncle is best developed in A. brocki, less so 

 in A, ephippiatus, and is weakest in A. i7i- 

 descens. Some specimens of A. iridescens pos- 

 sess pigmentation on the distal portions of the 

 dorsal rays, a condition not observed in the 

 other two species. In fresh specimens of A. 

 brocki and A. ephippiatus, the body musculature 

 is translucent. 



Etymology. — Named for the late Vernon E. 

 Brock in recognition of his contributions to 

 marine biology and his encouragement and 

 support of my studies on Hawaiian bathyal 

 fishes.
