A Rare Fish From Laguna Beach 



A photograph of this tish was sent to Prof. Gilbert to whom we 

 are indebted for the identification. The specimen was caught on 

 a hook and Hne not far from the laboratory. It was brought in by 

 Prof. A. M. Bean. No one in Laguna had ever seen anything like 

 it and no one would venture an opinion as to what it was. 



Alepisannis (cscidapius Bean 



Color, dark slaty gray above, sides silvery and irridescent, back 

 steel blue reflections. Under parts a lighter gray silvery. Adipose, 

 pectoral and caudal fins nearly black. Skin smooth, apparently 

 without scales. 



Total length 101 cm. Length of head from tip of mouth to 

 the back of the operculum 17 cm. Pectoral fin just back of oper- 

 culum, beginning of the dorsal just over it. Length of snout to front 

 of eye 6.6 cm. Eye 3.5 cm. long by 2.8 high. Breadth of pectoral 

 at base 2.8 cm. Fin rays of pectorals at base 14 in number, the 

 first and last are small, all the others branched. The first branch 

 of the 4th to the 13th is branched again. The fifth ray with its 

 branches is the longest, those on either side are quite long, so that 

 the fin ends in one or several long streamers. Greatest length of 

 fin 16.5 cm. 



Distance between back of fore fin and front of pelvic 19.2 cm. 

 Pelvic fins 8 rays, first and last not branched, membrans as on all 

 fins delicate and easily broken. Length of fin 5.7 cm. Anal opening 

 3 cm. from back of anal fins, ^ cm. long, not quite so wide. Dis- 

 tance from pectoral to anal fin 30 cm. Length of anal 10.8 cm. 17 

 fin rays all branched but first and last, the first branch of each 

 branched again. Longest part of fin (slantingly taken) 8 cm., one 

 to the 6th fin rays nearly as long. 



Tail symmetrical short rays in center, about 2 cm. long, at outer 

 margin longest about 14 cm., about 40 fin rays in the tail. 



Dorsal fin about 58 cm. long, 34 fin rays unbranched. Most of 

 the fin rays are long, 10 to 19 cm. Height of the fin through most 

 of its distance 9 cm.
