Draconetta in the deeper waters of the North Atlantic and Pacific. 
These little fishes resemble Callionymus, but the opercle, in- 
stead of the preopercle, bears spines. The Bovichthyide of New 
Zealand are also sculpin-like and perhaps belong to the same 
family. Dr. Boulenger places all these Antarctic forms with the 
foramen outside the hypercoracoid in one family, Notothentide. 
Several deep-sea fishes of this type have been lately described 
by Dr. Louis Dollo and others from the Patagonian region. 
One of these forms, Macrias amissus, lately named by Gill and 
Townsend, is five feet long, perhaps the largest deep-sea fish 
known, The family of Percophide, from Chile, is also closely

allied to these forms, the single species differing in slight respects 
of osteology. 
Closely related to the family of Notothentide and perhaps 
scarcely distinct from it is the small family of Pteropsaride, 
which differs in having but one lateral line and the foramen 
just above the lower edge of the hypercoracoid. The numer- 
ous species inhabit the middle Pacific, and are prettily colored 
fishes, looking like gobies. Pteropsaron is a Japanese genus, 
with high dorsal and anal fins; Parapercis is more widely diffused. 
Osurus schauinslandi is one of the neatest of the small fishes of 
Hawaii. Several species of Parapercis and Neopercis occur in
