Cephalopods 



of the 



Philippine Islands 



Introduction 



This report is based mostly on the extensive collections of cephalo- 

 pods made by the United States Fisheries steamer Albatross between 

 December 1907 and September 1909 in the Philippine Islands and 

 adjacent seas, and deposited in the United States National Museum, 



The Philippine cruise was under the direction of Dr. Hugh M. 

 Smith, then Deputy Commissioner of Fisheries. The late Dr. Paul 

 Bartsch, formerly Curator of Mollusks, U.S. National Museum, made 

 many of the cephalopod collections and I am greatly indebted to him 

 and his assistants for the accurate labeling of the collections and the 

 numerous supplementary notes which have proved invaluable during 

 this study. 



Collections of cephalopods taken at numerous trawling and dredging 

 stations were extensively supplemented by shore collections made both 

 by hand and by shore seines. In addition several valuable specimens 

 were obtained from local fish markets. 



Dr. Bartsch made frequent night use of a submarine electric light. 

 This hght, now in the possession of the U.S. National Museum, was 

 enclosed in a heavy waterproof brass-bound glass casing. According 

 to Dr. Bartsch, the Hght was lowered several hundred feet below the 

 surface and then gradually hauled upward, bringing with it many 

 species not easily taken at the surface. The efiicacy of this type of 

 collecting, now in use on most oceanographic vessels, is well demon- 

 strated by the large number of specimens bearing the legend "electric 

 light." 



Forty-six species of cephalopods were collected during this cruise, 

 from northern Luzon to Mindanao, the southern Sulu Archipelago, 

 and Balabac, south of Palawan.^ Of these, eight are species new to
