288 NEW GENERA AND SPECIES OF FISHES, 



work the genus Ophisomus and the subfamily Ophisomince have 

 been applied to certain blennioid fishes. Indeed it appears pro- 

 bable that the application of the name Ophisoma, as a substitute 

 for Ariosoma, to these eels was due to some confusion in their 

 author's mind between his genera Ophisomus ( = Pholis) and 

 Ariosoma, and was not of deliberate intention. 



The following species are referable to the genus Congrellus as 

 here restricted : — 



1. Congrellus balearicus. 



= Jfurcena balearica, De la Roche, Ann. Mus. xiii. 1809, 

 p. 327, f. iii. 

 Hab. — Mediterranean. 



la. Congrellus opisthophthalmus. 



= Conger opisthophthahnus, Ranzani, De Nov. Spec. Pise. 

 Disser. Prim. 16, pi. v. f. 1, 1838. 

 Hab. — Western Tropical Atlantic. 



lb. Congrellus mellissii. 



= Congromurcena meUissii, Giinther, Catal. Fish. viii. p. 42, 

 1870. 

 Hab. — St. Helena. 



2. Congrellus gilberti, nom.nov. 



= Op)hisoma balearicum, Gilbert, Proc. U.S. Nat. Mus. xiv. 

 1891, p. 349. 



Hab. — Bay of Panama. 1 Lord Howe Island. 



The small eel which I identified (see Rep. Lord Howe Island, 

 Fish. p. 72, 1889) with C. mellissii, possibly belongs to this form. 

 The specimen has unfortunately been mislaid. 



In writing of the Panama examples. Prof. Gilbert incidentally 

 refers to Ophisoma balearicum ( = Congrellus balearicus), and its 

 geographical varieties or, as I prefer to consider them, sub-species 

 in the following terms : — "They agree perfectly with the descrip- 

 tions of 0. compressum" (? impressum), " Poey, and 0. mellissii, 

 Giinther, and show in addition a brownish-black blotch below the 

 eye, not noted in descriptions of other species. From the current
