The differences alleged to exist between Himantololoiihus and Coryvol- 

 ophus are very marked, and if they really do exist, as stated, there can 

 be no doubt that the two should be kept apart. I know of no reason^ 

 except the singularity and greatness of the differences specified, for 

 doubting the correctness of Eeinhardt's observations on Himantolophus. 

 and prefer to assume their reliability rather than to discredit them, but 

 at the same time admit the desirability of confirmation. The burden 

 of proof meanwhile lies on those who would keep the forms together, 

 and not on those who would separate them. 



Finally, as to the genus Lojphius, it seems to me that the L. s€ti(fen(s 

 should be generically distinguished from the L. 2niicato)'ius, notwith- 

 standing the close external resemblance of the two. The two gTOups 

 may be diagnosed as follows : 



LoPHius. — Lophiids with vertebrae in considerable number, i. e., 27 — 

 31,* and toothed vomer. 



Tyj)e, Lophius jjiscaloriiis. 



LoPHio^rL^s. — Lophiids with vertebrie in diminished number. /. e., 

 about 19, and toothed vomer. 



Type, Lophiomus setigerus^Lophius seligerus, Wahl. 



It is surprising that the two have not been differentiated by Dr. Giin- 

 ther, inasmuch as he sometimes considers a difference of one or two ver- 

 tebrae to be sufiacient to distinguish families.
