Planarian worms were abundant on boulder and sandy clay 

 bottoms in 1-4 feet of water. They were rarest on clay and 

 mud bottoms, and were very rare in deep water, but two 

 specimens of Planaria macidata being found in water 10 and 

 14 feet deep. Miss Stringer comments on the lot as follows : 

 " In two cases I feel uncertain as it is possible that they repre- 

 sent a third species, Planaria gonocephala, a form often asso- 

 ciated with the two named. As they were in each vial merely 

 a single specimen with the others I am inclined to believe them 

 merely lacking in the typical pigmentation of one of the other 

 forms." The specimens in cjuestion are Field No. 959, col- 

 lected in algae in water 3J/2 feet deep. Identifications by Miss 

 Caroline E. Stringer. 



PHYLUM MOLLUSCOIDEA 



CLASS rOLYZOA 



Family Plumatellid^ 



Plumatella punctata Hancock. 



This bryozoan was common in many places on sand and 

 clay bottoms in water 3-5^ feet deep. In deeper water it 

 occurred on a mud bottom in 8-14 feet of water. In shallow 

 water it occurred on Scirpus anierlcanus, Scirpus occidentalis, 

 and on leaves of Polamogeton. Statoblasts were found abun- 

 dant in plankton obtained between Norcross Point and Dun- 

 ham Island, collected by Mr. A. A. Doolittle. Other species 

 of bryozoans will probably be found when special search is 

 made for them. Plumatella was identified by Dr. Paul S. 

 Welch.
