This species does not grow so large as the tunny. It is but rarely 
seen on our Atlantic coast, but is common in the Mediterranean. It is 
found on the Pacific coast as far north as San Francisco, and is abun- 
dant in the spawning season about the Santa Barbara Islands. As a 
food-fish it is of little value. It reaches a length of 3 feet and a weight 
of 20 pounds.

* Poey, who describes this species, writes as follows of the length of the pectoral, 
on which point alone it fails to agree with alalonga ; the pectoral is If in anal, 5 in 
total to base of caudal, f in ventral, f- in head. Liitken unites other disputed species, 
albicora, pacificus, germo, etc., with alalonga, and hesitates to do the same with subu- 
latus only on account of the length of its pectoral, which he thinks is a little too long 
for thynnus and not nearly long enough for alalonga.
