The following synoposis is an expression of my views of the relations of the 

 various members of the suborder. 



I. Branchial apertures above in the axilla of the pectoral 



fins. Mouth subterminal or inferior, the lower jaw 



being received within the upper Malth;eoidjE. 



II. Branchial apertures below, in or behind the inferior 



axilla? of the pectoral fins. Lower jaw projecting be- 

 yond or closing in front of upper. 



1. Head very large and flattened. Mouth transverse 



horizontal. Pyloric caeca Lophioid^e. 



2. Head compressed or cuboid. Mouth vertical or very 



oblique. Pyloric caeca none. Dorsal fin oblong. Ven- 



trals developed Antennarioid.e. 



2. Head compressed. Mouth with cleft subvertical. Py- 

 loric caeca two. Dorsal fin very short, like anal. Ven- 

 tral fins obsolete Ceuatioid.*. 



The following is an enumeration and synopsis of the representatives of 

 the several families. As Dr. Bleeker was the first to name one of the fami- 

 lies. I have credited it to him, although he neither defined it nor re- 

 stricted it in the same manner as is here done. As it is, however, only ne- 

 cessary that the type which the author considered as the representative of any 

 group should be known in order to necessitate the retention of a name. 

 Bleeker's must be retained. The generic name of Ferca, for example, is cred- 

 ited to Linnaeus, but, under that name, representatives of different families 

 were confounded by the author, and the name is now accepted in an entirely 

 different sense. The name alone is adopted, and not the idea or definition 

 connected with it by Linnaeus.
