Coelenterates from Lacuna Beach 



H. H. NININGER, A. M. BEAN AND OTHERS 



Corymorpha palma Torrey. Found at several places on the sand flats near 

 Balboa and Anaheim bays. 



Tubularia crocea Ag. Abundant on wharf and piles in Balboa bay. 



The only jellyfish which we have had determined is Scrippsia pacifica Torrey, Det. 

 Torrev. From surface waters near shore. 



Cribina xanthogrammica Brandt, Det. Torrey. The shore anemone is very 

 abundant and variable. 



Epiactis prolifera Ver. Specimens of red anemones, brown anemones with red 

 stripes and brown anemones were found under rocks at low tide. 



A small sand species was found on the sand flats at Anaheim Landing by W. 

 A. H. in September, 1917. We have not found any at Balboa or at Laguna which 

 seem to be this species. 



Ediuardsia sp. This was found very abundantly at Balboa bay and Anaheim 

 Landing, in the sand at low tide. W. A. H. 



Cerianthus xstuari Torrey. Possibly a small specimen collected at Balboa Bay 

 mav have belonged to this species. W. A. H. 



Cerianthus johnsoni Torrey. Two specimens of this species were collected at 

 Balboa Bay by Nininger. The following is his account of the species: 



"The anemone was taken from the muddy shore at low tide. In life the spread 

 of the tentacles was eight and a half inches. There was a folding in toward the 

 mouth of one or more of the tentacles almost all the time. Possibly they were carrying 

 food. In this the tentacles acted independently. When a particle was in the grasp 

 of the group of small central tentacles, the large tentacle or tentacles first involvd 

 returned to their former positions at once. 



The tube was found to be imbedded in the mud to a depth of sixteen inches. 

 Near the bottom of the tube the anemone was fastened to it by means of a cementing 

 substance much like the inner layers of the tube. 



The color of this specimen was pink. The color of another one was grayish with 

 the tentacles banded with pink." 



Living in or on the tube of one of these was an adult of the small crab Pinnixa 

 littoralis Holmes. 



Telesto amhigua Nutting. These little alcyonarians are quite abundant at Laguna 

 Beach, on the under sides of stones. 



Psammogorgia torreyi Nutting. Stems of this large branched alconarian were 

 dredged near Balboa in about twenty fathoms by A. M. Bean. 



From low tide and from dredging near shore one or possibly two species of stony 

 corrals were collected. 



Several small anemone-like forms were collected among algae and among the 

 roots of eel grass. One was a bright red with few tentacles. One had a light body 

 with blue tentacles.
