Notes on Annelids Collected During 1917 

 at Laguna Beach 



A number of sipunculids were collected but not as yet determined. There was 

 one large species found in the sand at Balboa and one small species found in the 

 sand and in a sponge. At Laguna in the roots of eel grass there were two medium 

 sized forms found, one with smooth gray skin, the other with rough brown skin, and 

 one small kind similar to the small one found at Balboa. In a worm colony of 

 Sahellaria a rough kind was found which seemed like one of the others. 



SYLLID.^ 



Trypanosylits gemmipara Johnson. Specimens of this large flat syllid were a 

 light pink. Most were obtained by dredging off shore at a depth of from 10 to 15 

 fathoms. A few were collected from algfe along shore. 



Syllis elongata Johnson. One specimen determined by Hamilton. Others obtained 

 may be the same species. 



A large number of other specimens are not yet determined. 



APHRODITID.« 



Several specimens from holdfasts and from dredgings have not yet been deter- 

 mined. 

 AMPHINOMID,^ 



Erythoe callfornica Johnson. ITnder stones. 



Etiphrosyne aurantlaca Johnson. A number of these short yellow worms were 

 obtained from holdfasts. 

 POLYNOID.T. 



Halosydna insiijnis Baird. A large number of these collected among mussels and 

 under stones. 



H. pulchra Johnson. Some of these found on Stichopus. A number of other 

 specimens have been sent away for determination, including some from the sand flats 

 of Balboa and from among hydroids. 

 PHYLLODOCID.^ 



Phyltodnce fenuginea Moore. Under stones at Laguna Beach. 



/'. meJi/tapillaia Moore. This was the largest of the family found at Laguna. 

 Among holdfasts and in the tube masses of Sahellaria califoniiia Fewk. 



A number of other species remain to be determined. 

 NEREID.?^. 



Nereis agassizi Ehl. \'ery common along shore and in holdfasts. 



N. vexillosa Grube. A few of these xvere determined. 



N. prncrra Ehl. Some of these found with the others of the family. 



A^. Tirt'ns Sars. A few specimens, smaller specimens than those reporter! by 

 Hamilton some years ago. 



A number of other species will probably be added from the undetermined ma- 

 terial. 

 NEPHTHVDID^. 



Nephthys cceca Fab. Low tide, Laguna Beach. One specimen.
