A Preliminary Report 



ON TUK 



Distribution of tlie Scallops and Glams in the Ghande- 

 leur Island Regions, Louisiana. 



By M. H. SPAULDING. 



I. INTRODUCTION. 



During the summer of 1904, Dr. James L. Kellogg, then 

 studying the oyster conditions at Cameron, visited the oyster 

 grounds of St. Bernard parish as the guest of the Louisiana 

 Oyster Commission. While in those waters he made a flying 

 trip to the Chandeleur Islands where he discovered the occur- 

 rence of the small scollop {Pecten irradians) and the "little 

 neck clam" {Venus meranaria), both of which are valuable 

 food forms in the New England States. 



As Dr. Kellogg was unable to complete the investigation 

 this winter as planned, I was engaged to determine the distribu- 

 tion and abundance of these mollusks in this region. In this 

 connection it is a great pleasure to acknowledge Pix)f. Guilbeau's 

 cordial co-operation with every stage of the work. I wish also 

 X\, express my heartiest thanks to Captain William Ileinemann 

 and Captain W. F. Streckert, the keeper and assistant keeper 

 respectively of the Chandeleur Light, for the many courtesies 

 which they have shown the party while we have been working 

 in these waters. I am also greatly indebted to Mr. L. R. Caiy, 

 Field Zoologist of the Station, with whom I was associated dur- 

 ing the greater part of the cruise. 



The station schooner "America" was placed at our disposal 

 and was brought to Gulfport, Miss., by Mr. Cary and party, 

 where I joined them in the latter part of January, when active 

 work was commenced. An examination of nearly all the avail- 

 able bottoms in this region has been made, the results of which 

 are given in the following report:
