brane. Tail not isocercal. Rays of dorsal all articulate ; all but a few of the last 

 simple. Ventral fins very small, reduced to a single ray. Pectorals moderate. Vent 

 normal. Pacific coast of tropical America. {MixpoS, small; S£dMo?,a band.) 



Microdesmua dipua Gilnther, 1. c. 



Gulf of California to Panama. The two remaining species of this family, Micro- 

 deamua i-etropinnis and Cerdale ionthas, both from Panama, are described by Jordan & 

 Gilbert, Bull. U. S. Fish Comm.. 1881,331. 



' ScYTALiscus Jordan & Gilbert. 



Proc. U. S. Nat. Mus., 1883, 111 ; name a substitute for Scytalina, preoccupied in Cole- 

 optera as Scytalina Erichson. It is doubtful whether this genus is really an ally of 

 Congrogadus. 



^Fierasfer duhiua Putnam =; Fierasfer arenicola Jordan &, Gilbert, Proc. U. S. Nat. 

 Mus., 1881, 363. Mazatlau. See Jordan «fe Gilbert, Proc. U. S. Nat. Mus., 1882, 629. 



Ophidium joaephi Girard and Ophidium gr'aellsi Poey (not of Jor. &. Gilb.) seem to 

 be identical with 0. marginatum. 



^The species described in the Synopsis as Ophidium gracllsi should stand as Ophi- 

 dion beani Jordan & Gilbert. See Proc. U. S. Nat. Mus., 1883, 143. 

 ''Otophidium Gill, gen. nov. 



Type Genypterus omostigma Jordan &, Gilbert. This genus dift'ors from Ophidium in 

 the presence of a sharp concealed spine on the opercle. The tyj>ical species has been 

 wrongly referred to Genypterus. 



•^The Brotuline genera {Bythites and Dinematichthys) have been erroneously placed 

 in the Synoposis among the Gadidw. For the characters of the Brotulida; see Gill, 

 Proc. Ac. Nat. Sci. Pbila., 1863, 2.'52; 1864, 200, and 1884, 1(>9, 175. These fishes are 

 certainly much nearer the Ophidiidce, or even the Lycadidce, than the Gadidce.
