CALLORHYNCHUS, (Gronov.), Cuvier. 



Callorltynchm, Gronovu's., Miis. Ichth., i, 59. Civier.— Et-giie Animal, cil. i, 1X17, 11, 1 10. 



Snout with a cartilaginous prominence, terminating in a cutaneous Haji. Two dorsal 

 tins, the anterior \vith a very long and strong sjjiue. Extremity of the tail'distinctly turned 

 upwards, with a fin along its lower edge, but without one above. Anal fin clo.se to the cau- 

 dal, sliort and deep. 



The typical species of this genus, €. mJlorhynchus (L.) [ = 0. antarctica (Lacepede) 

 Cuvier], has been hitherto found only in the Antarctic basin and the South Pacific. 



HYDROLAGUS, Gill. 



Hydrolagus, Gill, Proe. Acad. Nat. Sci. Phila., 1862, 331. 



Holocephali closely allied to Vliimwm, but with no filament at the tip of the tail, and 

 with bipartite posterior appendages.

 Hydrolagus ColUei, Gill, Proc. Ac. Nat. Sc. Phila., 1S62, 331. 



Tail simply tai)eiing, without filament. Three dorsal fins, besides the caudal: the first, 

 with the spine, is separated by a considerable interspace from the second; the three other 

 fins low, subcontinuous. Each clasper of the male is divided iuto two club-shaped branches, 

 which are leather shorter than the snout; both branches coated with the spiny meml)raue, 

 and the inner is not subdivided. Brown, silvery, ui)i)er parts with round yellow spots. 

 This form occurs only in the North Pacific. It is abundant about Puget Sound, and 

 in southeastern Alaska. It swims at the surface, and is abundant about the wharves at 

 Esquimalt, where it is called the "Eatfish." 



There is no evidence that it descends to very considerable depths. 



HARRIOTTA, Goode and Bean, n. g. 



Snout exceedingly elongate, with a cartilaginous midrib, and foliaceous lateral expan- 

 sions of the skin at its base. Two dorsal fins, the anterior with an immense triangular 

 spine, finely serrated, uiion its lateral edges. Anal fin reduced to a cutaneous fold. Lon- 

 gitudinal axis of the tail nearly the samc^ as that of the trunk, vei\y elongate, with filamen- 

 tous tip, the ftn below much more extensive than that above. No cephalic organ. Gill- 

 openings lateral ; separated by a wide isthmus. Olaspers small and simple. 



Tliis genus is named in honor of Thomas Harriott, the most eminent ])hilosopher and 

 naturalist of his day in England, who was a member of Raleigh's Itoaiioke colony in Vir- 

 ginia in 1585, and who published the first work in English on xVmericau natural history.
