On leaving San Diego one single gray whale was noted migrating south. 
This whale being an early single was probably a pregnant female. 
Four separate schools of Delphinus delphis were noted during an 11- 
minute period in the early afternoon. School sizes were 35^5* ^0-10, 
50-10, and 65-10. Three of the four schools were noted to have some in¬ 
dividuals with whitish patches on their dorsal fins. In one school 7 5 
percent of the dolphins had white patches in their dorsals. Only black 
dorsals were noted in one pod. 
Six single observations were made of California Sea Lions through 
the remainder of the day. 
b January 1968 
Three Delphinus delphis were noted slowly moving to the southeast. 
All had whitish areas on the dorsal. 
A group of 12-2 Risso Dolphins ( Grampus griseus) were noted travel¬ 
ing south. All-white dorsal surfaces and dorsal fins were noted for 
several of these dolphins. This coloration is normal for adults of this 
species. 
Also traveling south behind the Grampus were ca. 800-100 Right Whale 
Dolphins ( Lissodelphis borealis ) divided into 6-8 subgroups. The sub¬ 
groups traveled in a line one in back of the other, and each subgroup 
generally ’porpoised” out of the water in unison. Lissodelphis commonly 
associates with other genera of cetaceans. 
A pod of 10-2 Dali Porpoise were traveling south staying near the 
surface between breaths. 
Three probably Dali Porpoise were noted some distance from the ship.

A large school 30-5 Dali Porpoise were recorded traveling south. 
Two Dali Porpoise were noted diving and milling about the surface. 
These porpoises were probably feeding. 
Fifteen Fur Seals, all single except one pair, were recorded float¬ 
ing on their backs with flippers and tails in the air. 
5 January 1968 
One Fur Seal was recorded. 
6 January 1968 
Five pods of Dali Porpoise were noted this day. School size ranged 
from 6-2 to 12-2 with the other three being 10-2/5. A westerly direction 
was recorded for one pod.
