I therefore propose provisionally to associate these fishes in 

 a new order, which may be termed 



Xenoberyces. 

 The two families may be thus defined : — 



1. Stephanoberycidae. 



Air-bladder with a pneumatic duct ; dorsal and anal fins 

 without spines; pelvics abdominal or subabdominal, without 

 spine, 5- or 6-rajed. 3i gills. Nasal bones joined through- 

 out their length. 



Two genera : — Stephanoheryx, Gill, and Malacosarcus, 

 Guntli. 



2. Melampliaidae. 



Dorsal and anal fins with a few slender graduated spines ; 

 pelvics thoracic, of a slender spine and 6 to 9 soft rays ; 

 pelvic bones well behind the cleithra. 4 gills. Nasal bones 

 separate. 



Principal genera : — Melamphaes, Giinth., Plectromus, Gill, 

 Scopelogadus, Vaill., Anoplogaster, Giiath., and CauloJepisj
