JORDAN AND JORDAN: FISHES OF HAWAII. -3 



THE FISHES OF HAWAII. 

 Class LEPTOCARDII. 

 Order CIRROSTOMI. 



Family I. BRANCHIOSTOMID.E (The Lancelets). 

 Amphioxides Gill. 



1. Amphioxides pelagicus (Giinther). (J. & E., p. 33.) 



Pelagic. This diminutive lancelet, supposed to be distinguished by the 

 absence of buccal cirri and by its pelagic habit, is now regarded as a larval form. 

 The supposed genus is nearer Branchiostoma than Epigonichthys (Asymmetron) , 

 the only other genus of this family as yet'found in the open Pacific. 



Class ELASMOBRANCHII. 

 Order ASTEROSPONDYLI. 



Family II. SCYLLIORHINID^. 

 Apristurus Garman. 



2. Apristurus spongiceps (Gilbert). (Gilbert, p. 579.) 



Deep seas. This species is referred by Garman to Pristiurus, which genus is 

 characterized by a row of prickly scutes along the upper side of the tail. These 

 are not present in Gilbert's type, though perhaps they may have been lost in the 

 dredge. A cast in the Bishop Museum may belong to this species. Color plain 

 light brown; dorsal fins small, subequal, the first slightly in advance of ventrals. 

 The name Catulns is preoccupied in the Insecta. " 



Family III. GALEORHINID^. 



( Carcharhinidce of authors.) 



Galeorhinus Blainville. 



{Eugaleus Gill.) 



Amid the uncertainties regarding the application of the generic names Galeus 

 Rafinesque and Carcharias Cuvier, we here follow the. decision of the Interna- 

 tional Commission of Nomenclature. 



3. Galeorhinus japonicus (Miiller and Henle). (J. & E., p. 36.) 



Recorded from Laysan by Steindachner. Not rare in Japan.
