Narcetes stomias (Gilbert) 



One specimen fifteen inches long from station 5692, approximate 

 latitude 31°, 1076 fathoms, southwest of San Diego,, California, un- 

 questionably represents Gilbert's ptomias, but seems to belong in Narcetes 

 rather than Bathytroctes. Garman's Narcetes pleuriserialis is not very- 

 different and may be the same. 



Color, fresh, body and caudal dusky black, head bme-black. 



Bathysaurus mollis Giinther 

 Plate I, Figure 1 



One from station 5684, in 1760 fathoms. The only fish from this 

 station, which is off the west coast of southern Lower California, approxi- 

 mate latitude 23°. It is 17% inches long to base of caudal. 



Although we can find no character to separate our fish from mollis, 

 we give herewith a detailed description of this interesting specimen. 



Head, 4/2 in length to base of caudal; depth, 7%; eye, 7%, in head. Dorsal with 

 15 rays; anal 12; ventral 8. Scales (estimated) 100. Width of head }i its length; 

 gape 6/o in total length of fish. Teeth slightly barbed. 



Gape extending behind eye for a distance much greater than interorbital width; 

 equaling distance from center of eye to snout. Dorsal inserted 1% times the length of 

 its base behind snout. Length of fourth dorsal ray slightly greater than that of 

 maxillary. Mandible projecting beyond snout a distance equal to width of pupil. 

 Maxillary 1% in head. Interorbital width 5/2 in head. Seven to 8 large oval pores on 

 mandible, elongated except the two anterior ones. Head naked, except cheeks and 

 nape. Adipose dorsal present, half-way between origin of ventral and base of caudal. 

 Anal inserted behind dorsal a distance equal to the length of its own base. Anal base 

 1/3 in dorsal base. Ventral, pectoral and dorsal rays equal in length, % of head. Color 

 white, lining of gill cavity black. 



Myctophum californiense Eigenmann and Eigenmann 

 A specimen from station 5695 (southwest of the Santa Barbara 

 Islands, approximate latitude 34°) in 534 fathoms. 



Nannobrachium leu-copsarum (Eigenmann and Eigenmann) 

 A specimen from station 5693, southwest of the Santa Barbara 

 Islands, California, in 451 fathoms; one from station 5694 in 640 fathoms; 

 and a third (imperfect) from station 5697 between Monterey and Pt. 

 Conception, California, in 485 fathoms, latitudes 36° to 33°. 



Nannobrachium regale (Gilbert) 

 One large and one small specimen from station 5693, southwest of 

 the Santa Barbara Islands, California, in 451 fathoms, and a small one 

 from station 5695 in 534 fathoms, approximate latitudes 33° to 34°.
