CALLORHYNCHUS, (Gronov.), Cuvier. 



Callorhj/nchus, Guoxovn's., Mns. hhth., i, 59. C'lViER. — Eegiie Animal, ed. i, 1817, ll, 140. 



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

 fins, the anterior \Anth a very long and strong spine. Extremity of the tail distinctly turned 

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

 dal, short and deep. 



The typical species of this genus, C. caUorhynchiis (L.) \ = C. antnrcticd (Lacei)ede) 

 Cu\-ierj, has been hitherto found only in the Antarctic basin and the South Pacilic. 



HYDROLAGUS, Gill. 



Hydrolagus, Gill, Proc. Acad. Nat. Sci. Phila., 186-2, 331. 



HoUcephali closely allied to Chitncvra, but with no filament at the tip of the tail, and 

 with bipartite posterior appendages.

 ffijdrnlagun Colliei, Gill, Proc. Ac. Nat. Sc. Phila., 1862, 331. 



Tail .simply tai>eriiig, without filament. Tliree dorsal fins, besides the caudal: the first, 

 with the spine, is separated by a coiisiderabh! interspace from the second; tlic three otlu'r 

 fins low, subcontinuous. Each dasper of the male is divided into two clubsliaped branches, 

 which are rather shorter than the snout; both branches coated with the spiny membrane, 

 and the inner is not subdivided. Brown, silvery, ujiper parts with round yellow sixjts. 

 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, upon its lateral edges. Anal fin reduced to a cutaneous fold. Lon- 

 gitudinal axis of the tail nearly the same as that of the trunk, very elongate, with filamen- 

 tous tip, the fin below much more extensive than that above. No cei)hahc organ. Gill- 

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



This genus is named in honor of Thomas Harriott, the most eminent i)hilosopher and 

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

 ginia in 1585, and who published the fir.st work in Engli.sh on American natural history.
