used the results of photophore anatomy research by Bassot ( 1 966, 

 1971) to support their conclusions. These results seemingly 

 completely supported Weitzman's referral of genera to family 

 groups and agreed with Ahlstrom except for placement of three 

 genera — C'lr/or/iowc, Diplophos (including Mandncus), and 

 Tnplophos. 



One of us (Weitzman), continues to study relationships of the 

 stomiiforms with elongate gill rakers in adults and we offer the 

 following analysis as a current comment on the status of our 

 knowledge of these fishes. The two concepts of relationships by 

 Ahlstrom and Weitzman may be compared as follows: Ahlstrom 



(1974:670-672) stressed relationships of taxa based on photo- 

 phore patterns and development. Ahlstrom (1974:672) consid- 

 ered the stomiiforms with elongate gill rakers in adults as a 

 group comprised of three groups of genera, with any subdivision 

 being into two subfamilies based on photophores occurring in- 

 dividually or in clustered groups. These groups of genera in- 

 clude: (I) Those with individual separate photophores, most of 

 the photophores developing simultaneously and initiated as a 

 "white" photophore stage. This group includes Manducus, Dip- 

 lophos, Cyclothone. Yarella, Pollichthys, V'inciguerha. Wood- 

 sia, Ichlhyococcus. and presumably Triplophos and Polymetme,
