Ascidia californica Ritter and Forsythe
These simple forms were found quite abundantly under stones and in kelp holdfasts. The form of the body was determined largely by the position the animal took on the stone or seaweed.
Styela barnharti Ritter and Forsythe
The specimens obtained were young, simple, of a redish-brown color and about 4 mm. high. They were found under stones at low tide but not as commonly as some others.
Styla montereyensis Dall
A single specimen of this large, simple species was taken just off shore. It was slender at the base, expanded near the openings and of a redish-brown color.
Euherdmania claviformis Ritter
This slender species was often found in clusters under stones. They were about 2 mm. in diameter and 10-20 mm. long, sometimes free from sand, at other times covered with sand grains.
Goodsiria dura Ritter
Bright red or orange masses of these were often found in bits of seaweed from deeper water. The individuals were 2 to 3 mm. across and often closely massed on the seaweed or other support.
