544 NEW FISHES FROM PACIFIC COAST GILBERT. 



Second dorsal inserted over the anal, its base one-third that of first 

 dorsal, and less than one-half its distance from base of upper caudal 

 lobe. Its upper margin is much less concave than that of anal, and the 

 fin is smaller. 



Lower caudal lobe nearly half the upper, which is 3| in total length. 



Light gray above, whitish below, the fins conspicuously margined 

 with white in the largest specimen obtained, without margins in the 

 others. 



This species is very abundant at the Eevillagigedo Islands, speci- 

 mens being secured at Clarion and Socorro. A siugle individual was 

 also obtained at Magdalena Bay, Lower California. It reaches a length 

 of at least 8 feet. This is the species recorded by Jordan and Bollman 

 from the Galapagos Islands as Eulamia lamieUa. From lamieUa it 

 diflt'ers in the notched teeth and the anterior position of the first dorsal. 



6. Stolephorus cultratus sp. iiov. 



Body compressed, of medium depth, tlie abdomen compressed to an 

 edge both iu front of and behind the ventral fins, but without serra- 

 tions. Behind the ventrals the edge is sharply carinate. 



Head slender and shar]>, the snout long and compressed, extending 

 beyond tip of lower jaw for a distance nearly equaling diameter of orbit. 

 Maxillary abruptly widened behind angle of mouth, then tapering to a 

 rather sharp point which extends beyond mandibular articulation nearly 

 to gill-opening. 



Teeth in lower jaw small but distinctly visible ; in upper jaw growing 

 larger towards tip of maxillary, where they are directed forwards. 



Opercle narrow, scarcely as wide as exposed portion of preopercle, 

 the margin moderately oblique, not wavy. 



Front of dorsal midway between base of caudal and front of pupil. 

 Base of ventrals midway between origin of anal and articulation of 

 mandible. Origin of anal behind last ray of dorsal. 



Scales closely adherent, rather thick and firm. 



Head 3§ iu length ; depth j^. D. 12 ; A. 20. Lat. 1. 40. 



Color olivaceous, the dorsal region with black specking. A silvery 

 band along middle of sides very narrow anteriorly but increasing iu 

 width to opposite anal fin, where it is as wide as eye. Snout and mar- 

 gin of caudal lobes dusky. 



A single specimen, 3;\ inches long, from Santa Margarita Island, off 

 the coast of Lower California. 



7. Myctophum regale sp. uoa'. 



In the type specimen the scales are whollj' wanting, with tlie excep- 

 tion of two or three along the base of the anal, which have entire mar- 

 gins. The scars in the skin indicate that the scales along the lateral 

 line were enlarged, those on middle of rail being twice the size of the 

 ordinary scales. The species closely' resembles in appearance Mycto- 

 phum {Nannobrachiian) n'ujer (liinther, but ditt'ers in the relative posi-
