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 Bovichthyidce 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, N ototheniidcs . 

 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 Percophidce, from Chile, is also closely

allied to these forms, the single species differing in slight respects 

 of osteology. 



Closely related to the family of Nototheniidcz and perhaps 

 scarcely distinct from it is the small family of Pteropsarida, 

 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
