In the open sea many slender larvae, similar in form to 

 Stolephorns miaj'ckits were obtained by the use of dyna- 

 mite. The number of anal rays shows that these larv« 

 belong to the present species. 



48. Stolephorus lucidus Jordan & Gilbert. 

 Originally found by Dr. Gilbert in the Astillero at Ma- 



zatlan; not obtained by us. 



49. Stolephorus scofieldi Jordan & Culver, n. sp. 



* Head 3^ to 3^^ i'^ length to base of caudal; depth 

 4/^ to 5; eye 3^ to 4 in head; dorsal 12; anal 25 or 

 26; scales 41 or 42. 



Close to Stolephorics delicatissimus, but with larger 

 head, wider lateral band, and greater number of dorsal 

 and anal rays. 



Body somewhat compressed and elevated, the belly not 

 carinated or serrated. Teeth in both jaws, and on pala- 

 tines; a few on vomer. Maxillary covered with teeth its 

 entire length and reaching beyond base of mandible, but 

 not to opercular margin. 



Gill-rakers 10-]- 12, the longest a little more than half 

 the eye. 



Origin of dorsal midway between base of median cau- 

 dal rays and center of eye; anal not quite as long as head, 

 its origin below the middle of dorsal. Lower caudal 

 lobe longer than upper; longest ray equaling length of
