A REPORT ON SOME ARENACEOUS FORAMINIFERA 



(Plates 1-12) 



Joseph A. Cushman and Irene McCulloch 



From relatively shallow waters along the eastern edge of the Pacific 

 from Seward, Alaska, to areas off the coast of Peru, large numbers of 

 bottom samples have been assembled for study. 



That such a collection for study exists is due almost entirely to the 

 interest, energy, and efficiency of Captain Hancock personally. 



In this connection due credit must be given to a mechanical genius, 

 Alex Campbell, Chief Engineer of the Velero III, for devising all sorts 

 of mud dippers when needed, ranging from a section of pipe to most 

 efficient metal snappers. The sincere appreciation herein expressed means 

 so much more when it is remembered that the several specialists on 

 each expedition always became too engrossed in special fields to devote 

 time and energy to collecting material outside their special interests. 



From time to time additional material has been added to the collec- 

 tions brought back by the Velero III, by people who were visiting re- 

 mote areas and knew the value of comparative material in connection 

 with such extensive studies. Such aid has been invaluable and the hope 

 is expressed that even greater amounts of such material will be avail- 

 able in the future for comparative studies. 



Unfortunately, when the system of numbering samples was begun 

 there was no way of anticipating the scope of the work in the future. 

 In 1932 the plan of arbitrarily using the figure "1" for all samples off 

 San Pedro; the figure "2" to begin the number of all samples off 

 Mexico; "3" for South America; "4" for Galapagos; "5" for South 

 America was adopted. Shortly afterward, a trip to Alaska resulted in 

 a series beginning with "A"; "V" for British Columbia; "W" for 

 Washington; "C" for one collection of samples from off the coast of 

 northern California to Los Angeles. 



Beginning northward and proceeding southward the station lists 

 arranged in tables record the available data. 



The arenaceous foraminifera recorded in the following pages do 

 not represent all the species obtained in the dredgings. As in all similar 

 collections there are single specimens, or incomplete ones, or specimens 

 representing the early stages alone. While it may be evident that these
