AMMOCHARID^ 



Ammochares occidentalis Johnson. Several specimens were found among the roots 

 of eel grass at Laguna last Summer. The tube of one specimen at least was made of 

 overlapping but regular fragments of shell. Another specimen was dredged with a 

 similar regular tube of shell fragments. 



SABELLID^E 



A number of species were collected, but none as yet determined. Sabella elegans 

 Bush seems to be in the collection. Most specimens were taken from holdfasts or 

 dredged off shore. One was found in the neighborhood of a sabellarian worm colony 

 and some were under rock ledges. 



SERPULID^ 



But few of these were collected. 



Serpula colombiana Johnson was the only one determined. 



HERMELLID^ 



Sabellaria californica Fewkes. Enormous colonies of this species are found along 

 the shores in many places. 



S. cementarium Moore. This species is usually found farther out and although 

 common is usually found in much smaller numbers in more isolated tubes. 



In the lakes back from Laguna Beach and in the streams, a leech is very common. 

 Specimens sent to the U. S. Nat. Museum were determined as Erpsodella punctata 

 Leidy. W. A. H.
