SUPn^EME.'VTARY IVOTE ON THE PEDIt'UIiATI. 



BY THEODORE OILL. 



In the i^roceedings of the United States Xational Museum for 187S 

 (v. 1, pp. 215-232), I have given the characteristics of the families, sub- 

 families, and genera of the Pediculate fishes. The present communica- 

 tion will supplement the article in question by detailing the synonyms 

 of the families and subfamilies. The generic synonyms have been al- 

 readv indicated. 



I. 



Since the publication of the "Note on the Antennariidae'' (op cit., pp. 

 221-222), a "new genus" has been added to the family by Dr. A. Giin- 

 ther, whicli may be distinguished as follows : 



Tetrabrachium. 



= Tetraltracliium, Giluther, Zool. Cballeuj^er, part C, p. 44, 1880. 



Antennariids with the body oblong conic from the head backwards; 

 the skin naked; a compressed cuboidal head; small A^ertical mouth; 

 dorsal spines (3) isolated and dwarfed, but exserted ; second largest, 

 " wide and fringed ; " dorsal and anal fins low, long, and free behind ; and 

 pectorals with the upper portion (4 rays) detached from the lower. 



Type, Tetrabracliiuiu ocellatuni, Gilnther, Zool. Challenger, part 6, p. 45, pi. 19, 1'. c. 



■ Ocean south of New Guinea (specimen obtained at a depth of 28. 

 fathoms). 



All that has been suggested as to this interesting form is what may 

 be implied by the reference to the " Pedicalidae," which, as appears b}- 

 the "Systematic List" at the end of the volume (p. 78), is simply a mis- 

 print for Pediculati. Possibly the nearest ally of the genus is Histio- 

 pJiryne^ but it appears to be quite an isolated form. 



Dr. Liitken (Videusk. Medd. fra den Naturhist. Foren. Kjobeuhavn, 

 1879-'80, pp. 67-68) has objected inter alia to the generic differentiation 

 of Gorynolophus, but has not traversed or even met the reasons and ar- 

 guments in favor thereof submitted by me (Proc. TJ. S. Nat. Mus., v. 1, 

 p. 230). I therefore need only refer again to my original statement.
