beginning of soft dorsal 3 times length of head; length of head twice its 

 greatest depth, 5 in distance to vent; appendage of mandible | as long 

 as eye; free tip of caudal eye. Orange or yellowish, body with a 

 blackish 'longitudinal stripe; anal darker in color than dorsal. Length 

 about 12 inches. Aleutian Islands ; rare ; in water of moderate depth. Here 

 described from the original type from Unalaaka; 2 other specimens 

 known, the one studied by Dr. Gilbert taken in the entrance to the har- 

 bor of Unalaska. (Named for Dr. George Brown Goode.)

Group OPHLUIOIDEA. 

 (THE EEL-POUTS.) 



This group, as a whole, agrees with the Blennioidea in all respects, 

 except that no spines are developed in any of the fins, save sometimes 

 in the posterior part of the dorsal. From the Anacanthinl, with which the 

 Ophidioidea agree in the jugular ventral s and in the absence of spines, 

 they are separated by the form of the hypercoracoid, which is perforate, as 

 in ordinary fishes. The group is a very large and varied one, widely dis- 

 tributed in all seas. 



a. Pseudobranchire well developed, very rarely small or obsolete. 



b. Veiitral fins jugular, inserted much behind the eye, often wanting, never 



filamentous. 



c. Gill membranes broadly united, free from the isthmus ; ventrals wanting ; 

 no scales. SOYTALINID^E, ccv. 



cc. Gill membranes united to the isthmus, the gill openings lateral. 



ZOARCID^E, ccvi. 

 bb. Ventral fins developed as slender filaments attached at the throat not far 



behind eye. 

 e. Gill membranes broadly attached to the isthmus ; no scales. 



DEREPODICHTHYUXE, ccvii. 

 ee. Gill membranes nearly separate, free from the isthmus ; body scaly. 



OPHIDIID.E, ccvm. 



aa. Pseudobranohiae absent (or rudimentary in some Brotulidce). 

 /. Ventral fins wanting ; no scales. 



g. Vent normal, well behind pectorals. LYCODAPODIMS, ccix. 



gg. Vent at the throat. FIERASFERIDJE, ccx. 



/. Ventral fins well developed; vent posterior, normal. 



h. Dorsal fin single, low; ventral fins short. BROTULID.E, ccxi. 



hh. Dorsal fins 2, the anterior, at the nape, of a single long ray; ventral 



fins elongate. BREGMACEROTID.E, ccxn. 



Family CCV. SCYTALINID^E. 



Body elongate, compressed, eel-shaped, naked. Head depressed, with 

 tumid cheeks, like the head of a snake. Mouth moderate, horizontal, the 

 lower jaw the longer; teeth in a single series in the jaws, vomer, and 

 palatines; no barbels. Gills 4, a slit behind the fourth; pseudobranchise 

 present. Gill membranes broadly connected, free from the isthmus. Dor-
