Ophidoidea with jugular ventrals reduced to one or two rays, 

 and the anus in the anterior half of the length. 



This family is quite rich in deep-sea types, and may be divided 

 into various subfamilies, four of which (Brotulinse, Brosmophy- 

 cinae, Bythitinse, and Sirembina^) have already been indicated and 

 defined (see sj^nonymy). The deep-sea forms chiefly belong to 

 the subfamily Brosmophycinse, and perhaps one or two still undif- 

 ferentiated ones whose definition is not at present possible. 



BROTULOPHIDID^. 



Synonymy. 



= Brotulophididm, Gill, Arrangement Families of Fishes, p. 3, 1872. 

 Ophidiidm {BrotuUna), gen., Giinther. 



Ophidioidea with subbrachial (or thoracic) ventrals reduced to 

 simple filaments, and anus in the anterior half of the length. 



The single genus Brotulophis, for which this family has been 

 distinguished, is still very imperfectly known, and its aflSnities 

 are doubtful.
