4. A Revision of the Fishes of the Family Galavide.

(Plates X.—XITI.*) 
The Galaxiide are a family of Teleostean Fishes which are placed 
by Boulenger in the Haplomi, a suborder defined by the abdominal 
ventral fins, the persistent pneumatic duct, and the absence of a 
mesocoracoid element in the pectoral arch. 
They may be thus defined :— 
Maxillary behind the premaxillary and toothless, but to a 
certain extent bordering the mouth. Parietals in contact, 
separating the frontals from the supraoccipital; orbitosphenoid, 
basisphenoid, and opisthotic wanting; pro-otics not forming a 
roof for the eye-muscle canal, which is confluent with the cranial 
cavity ; mesethmoid small, unpaired. Ribs attached to auto- 
genous pavapophyses; epipleurals and epineurals present. Post- 
temporal simple, attached to the epiotic; pectoral pterygoids 
normal, 4 in number. 5 to 11 branchiostegals; gill-membranes 
free from the isthmus; pseudobranchie present; four gills, a 
slit behind the fourth. Body naked. No adipose fin, Pectorals 
placed low; ventrals, if present, with 6 or 7 rays. Air-bladder 
present. Ova falling into the abdominal cavity before extrusion, 
The closely allied Haplochitonidee differ in the greater develop- 
ment of the premaxillaries, the presence of a roof for the eye- 
muscle canal, formed by the pro-otics, and in having an adipose fin. 
The Esocide of the Northern Hemisphere resemble the 
Galaxiidee and Haplochitonide of the Southern in the primitive 
structure of the vertebral column, also in the shape of the cranium, 
the orbitosphenoid wanting and the opisthotic very small or absent. 
However, the presence of well-developed paired ethmoids and the 
separation of the parietals by the supraoccipital are cranial 
differences of considerable importance.
