tinct facies of adult and larval characters. Pax- 

 ton placed the remaining 14 genera into two 

 tribes, the Lampanyctini and Gymnoscopelini. 

 On the basis of larval characters, we cannot con- 

 cur with his distribution of genera among the 

 two tribes. He included eight genera (Lampa- 

 nyctus, Stenobrachius, Triphoturus, Ceratosco- 

 pelus, Lepidophanes, Bolinichthys, Taavingich- 

 thys, and Lampadena) in the tribe Lampanyctini 

 and restricted the tribe Gymnoscopelini to six 

 genera (Gymnoscopelus, Lampanyctodes, Notos- 

 copeliis, Lampichthys, Scopelopsis, and Hinto- 

 nia). Paxton found no single character that 



would differentiate any of the four tribes from 

 all others in the subfamily and relied on a com- 

 bination of osteological and photophore charac- 

 ters to define the tribes. His most trenchant 

 characters separating the Gymnoscopelini from 

 the Lampanyctini were the presence of a supra- 

 maxillary bone in the Gymnoscopelini and its 

 absence in the Lampanyctini and the presence 

 of a Dn photophore in the former and its absence 

 in the latter. 



Our findings in the larvae suggest a diflFerent 

 distribution of genera for the two tribes. On 

 the basis of larval characters described earlier
