1936] MAMMALS OF OREGON 349 



PHOCAENA PHOCOENA (LINNAEUS) 

 HARBOR PORPOISE ; BAY PORPOISE 



[Delphinus] pJiocoena Linnaeus, Syst. Nat., ed. 10, p. 77, 1758. (Synonyms: 

 Phocaena comnwnis Lesson; Phocaena vomerina Gill). 



Type locality. Swedish seas. 



General characters. Size small, less than 6 feet in total length ; form short 

 and thick (pi. 50, D) ; head short; dorsal fin small, triangular, and about 

 middle of back; teeth thin and flat, in two from San Francisco Bay, Calif., 

 26 above and 24 below and 21 above and 24 below (Scammon, 181 '4, p. 95). 

 Black above, paler, gray or white below, sometimes with white markings on 

 tail and pectorals. 



Measurements. Of male from Port Townsend, Wash., April 28, 18'69 (Scam- 

 mon) : Total length, 4 feet, 8 inches; length of pectorals, 8 inches; width orf 

 tail, 14 inches ; height of dorsal fin, 3% inches ; thickness of blubber, 1 inch. 



Distribution and habitat. Inhabits Atlantic and Pacific coastal 

 bays and harbors, possibly including many forms. Noted by S'cam- 

 mon along the Pacific coast from Mexico to Puget Sound and in the 

 lower waters of the Columbia River, in Cathlamet Bay, and off 

 Astoria. He says they are never found in large schools, but occa- 

 sionally 6 or 8 may be seen together, appearing at the surface singly 

 or 2 or 3 together. They make a quick puff and quickly disappear 

 below the surface, seeming to prefer the darkness below and never 

 making playful gambols as do the larger porpoises (Scammon, 1874', 

 p. 97). 



They feed upon small fish and are occasionally taken in nets 

 hauled by the fishermen. The Indians frequently shoot or capture 

 them in the sheltered coastal waters and regard their flesh as a great 

 delicacy.
