Sahellaria californica Fewkes. 



This form was found in large colonies in the protected 

 crevasses of cliffs west of the laboratory. The colonies are 

 some twenty feet long, two feet wide and ten inches thick. The 

 tubes are of loosely agglutinated sand and are crowded very 

 closely together with their mouths evenly disposed over the 

 surface of the colony. 



Another species lives singly in very hard, thick sand tubes. 

 Some specimens have algse growing on their opercula. 



TURBELL.'\RIA 

 I have three kinds of these "flat worms" in my collection. They 

 are found under partly submerged stones. 



Nemertinea 

 There are seven different nemertines in the collection. They are 

 recorded from holdfasts, seaweed tangles and from among ver- 

 metus tubes. 



Nematoda 

 There are two or three different marine nematodes in the collec- 

 tion. They are most common in the finer moss. 



SiPUNCULOIDEA 

 There are two kinds of sipunculids, which seem quite distinct. 

 Taken from eel grass roots, from under rocks and mussels. 



The specimens were identified from the following papers:
