Note: Gago and Lavenberg (1992) analyzed character variation of Centrobranchus worldwide and 

 determined that C. choerocephahis and C. brevirostris, two species formerly recognized in the northeast 

 Pacific (Wisner 1976), could not be distinguished from C. nigroocellatus.

Note: Badcock and Araujo (1988) synonym ized Pacific C. warmingii with Ceratoscopelus lownsendihased 

 on a worldwide study of C. warmingii. The two species differ in the arrangement of luminous tissue. 

 Principally, C. warmingii lacks the extensive supraorbital luminous tissue that is characteristic of adult 

 eastern Pacific C. townsendi. Also, the supra- and infracaudal series of luminous patches extends farther 

 posteriad in C. warmingii compared with C. townsendi. In this survey the specific distinction of the two 

 forms is maintained to show how they are delimited geographically, with a relatively narrow zone of 

 overlap (Fig. 23).
