Figure 18. — Distribution of larvae of the lophiiform families Caulophrynidae (Caidophryne jordani) (open hex- 

 agon with dot), Gigantactinidae {Gigantactis sp.) (open triangle with dot), Himantolophidae (Hiinantoloplms sp.) 

 (open diamond with dot), Linophrynidae (2 or more genera represented) (open square with dot), and Melanoceti-

Caulophrynidae 



(2 occurrences, 2 larvae) 



Bertelsen referred all material of Caulophryn- 

 idae to a single species, Caidophryne jordani 

 Goode and Bean. This is the only ceratioid fish 

 known to develop pelvic fins. The two occur- 

 rences (Figure 18) were north of the equator 

 in the pattern occupied by the middle vessel. 



Centrophrynidae 



(1 occurrence, 1 larva) 



A single specimen was obtained of Centro- 

 phyrne spinulosa Regan and Trewavas in the oflF- 

 shore pattern (Station 45.325). Larvae of this 

 species develop a digitiform barbel on the throat, 

 a character unique to the species.
