off Washington (fig. 1). Boat hunting days in 

 1959 were: California - 120; Oregon - 16; 

 Washington - 34. 



One vessel arrived in central California in 

 late November 1960. It cruised between Point 

 Arena and Pigeon Point until 14 December. It 

 resumed collecting on 5 January 1961 and con- 

 tinued to operate between Point Reyes and Point 

 Sur until 1 April, except from 15 January to 25 

 February when it was cruising between Point 

 Sur and Cortes Bank. In April the vessel moved 

 through northern California and Oregon waters 

 to Washington. One or two vessels cruised off 

 Washington from 23 March through 25 April 

 (fig. 2). Boat hunting days inlate 1960and 1961 

 were: California - 70; Oregon - 4; Washington 

 - 36. 



Symbols used to identify specimens (ex- 

 ample: Tac-50-lB) indicate the vessel, year, 

 specimen number, and species; TACOMA = 

 Tac, MORNING STAR = MS. 



The order followed in listing the cetaceans 

 observed is generally that of Miller and 

 Kellogg (1955). 



In the figures the species are indicated by 

 various symbols. Inside each species symbol 

 is a sign indicating the month in which the 

 observation occurred. Observations for 1958 

 and 1959 are grouped together in figures 3-8 

 and those for 1960 and 196l in figures 9-12. 



SPECIES RECORDS 



Physeter catodon , sperm whale (figs. 3 and 9) 



No attempt was made to record the sex of 

 sperm whales. Both sexes are taken off San 

 Francisco and brought to the whaling stations 

 at Richmond, Calif., in San Francisco Bay. 

 Although pregnant females are found at the 

 stations, we observed no sperm whales accom- 

 panied by young in late winter and spring. 



Delphinus delphis , 



(figs. 4 and 11) 



common dolphin 



Tomilin (1957) placed the Pacific dolphin 

 Delphinus delphis bairdi as a race of the com- 

 mon dolphin Delphinus delphis . 



No common dolphins were identified in 1958. 

 In 1959, 22 sightings were made between Point 

 Reyes and San Miguel Island, Calif. Three 

 groups were seen southwest of San Miguel 

 Island in January, at distances of 12, 2 3, and 

 24 miles offshore. In February 14 groups were 

 sighted between Point Conception and Cape San 

 Martin, from 15 to 40 miles offshore, and one 

 group 23 miles southwest of Point Reyes. Four 

 groups were sighted in March, three about 26 

 miles southwest of Pigeon Point and one 5 miles 

 west of Cape San Martin. In 1961, six groups 

 were sighted between San Nicolas Island and 

 Monterey Bay. Two concentrations were ob- 

 served, one of about 200 animals, 10 miles south 



of San Nicolas Island, and one of about 100, 20 

 miles west of Morro Bay. None was found inside 

 the 100-fm. curve. Group size ranged from 4 

 to over 100. Common dolphins and Pacific 

 striped dolphins were commonly found in mixed 

 groups. We collected four common dolphins as 

 follows :

Lissodelphls borealis , northern right whale 

 dolphin (figs. 3 and 11) 



This species was seen once on 13 March 

 1958, when several individuals appeared to- 

 gether with Pacific striped dolphins ( Lagenor- 

 hynchus obliquidens ) in a large school of 

 Risso's dolphins ( Grampus griseus ), about 35 

 miles southwest of Point Arena. In 1959, three 

 observations were made: on 3 February a 

 school of more than 100 animals 45 miles west 

 of Morro Bay; on 4 February a congregation of 

 more than 100 right whale dolphins and more 

 than 50 Risso's dolphins was seen 60 miles 

 west of Morro Bay; and the third group, which 

 had more than 10 animals, was seen on 5 

 February, 40 miles southwest of Morro Bay. 

 On 18 January 1961, a mixed school of about
