once netted a school of true eastern mackerel off Santa Catalina Island. 

 J. Weinniiller, of Santa Barbara, lias also taken them occasionally off 

 Anacapa Island. There is little doubt of the casual occurrence of this 

 species on our Pacific coast. 



87. Scomber pneumatophorus Delaroche. — Easter Mackerel; Tin'ker Maclcerel; Little 



Madcerel. 

 (Scomber diego Ayres; Scomber dekayi Storer. ) 

 From Monterey southward ; coming- in irregular and often large schools 

 in summer and fall. It reaches a length of a little more than a foot. 



88. Orcynus alalonga (Gmelin) Risso. — Albicore. 



{OrctiHus pacifiCHS Cooper; Thyniius pacificus C. & V.) 



From San Francisco southward; abundant in summer south of Point 

 Concepcion and taken by trolling. It is found in deeper water than the 

 bonito, being rarely taken within 6 miles of the shore. It feeds on 

 anchovy and squid, and occasionally rare deep-water fishes are found 

 in its stomach. It is shorter and deeper than the bonito, weighing 12 

 to 15 pounds. It is little valued as a food-fish, selling at about 25 cents. 

 It is caught chiefly for sport, as it is a very gamy fish. 



Another Orcynus, known as the "tuna", exists about Santa Cruz 

 Island, but we failed to obtain it. 



89. Sarda chilensis (Cuvicr & Valenciennes) J. & G. — Bonito; S2)a)iish Mackerel; 



Skipjack ; Tuna. 



From Monterey southward; very abundant everywhere in summer, 

 when it is taken in great numbers, by trolling, at a distance of 2 or 3 

 miles from shore. It is extensively salted and dried, but the flesh is 

 rather coarse, and it brings a lower i^rice than the yellow-tail and bar- 

 racuda. It reaches a weight of about 12 pounds and sells at about 25 

 cents. After the sjiawning season the young are very abundant in the 

 kelp. 



90. Scomberomorus concolor (Lockiugtou) Jordan & Gilbert. 



Monterey Bay. It comes to the market at San Francisco from Soquel 

 every year, but in small numbers. Barely more than 18 or 20 come in 

 in a single season. This year (1880) upwards of 40 were taken, nearly 

 half of which were secured by us. Its usual prire in the market of San 

 Francisco is about $2.50. The female is marked by two rows of alter- 

 nating, round, bronze spots about the size of the imi^il. 



Family CORYPH^NID^. 



91. Coryphaena (species). 



A dolphin came ashore in a storm at Caj'ucos a few years since. Its 

 captor and eater informs us that he is well acquainted with the dol- 

 phin in Mexican waters, and that this was the same fish.
