CEPHALOPODS OF THE PHILIPPINE ISLANDS 149 



The color in alcohol is brownish yellow but probably the specimens 

 were transparent when ahve, with only large scattered chromato- 

 phores on the mantle, head, and funnel. 



Type. — Zoological Museum, Copenhagen. 



Type locality. — Azores. 



Discussion. — Certain discrepancies occur between these specimens 

 and the published accounts of this species. Most important of these 

 is the nature of the hectocotylus. Undoubtedly the differences in 

 this organ are due to growth; however, Lonnberg stated that there 

 are two rows of minute suckers to the end of the arm. Sasaki's 

 description is also at variance, even though his largest specimen should 

 have shown all the structures found on the present specimens of a 

 similar size. Perhaps there is in this species a certain amount of 

 v^ariation in the structure. Certainly it is noteworthy that either the 

 left or right ventral arms may be hectocotylized, and that this charac- 

 ter is at variance with all the published descriptions. It may be 

 noted further that the terminal minute suckers have well-developed 

 apertures with smooth rings and are not mere pads or peduncles 

 minus the suckers, as Pfeffer suggested. 



The number of photophores on the eyeball also seems to vary, 

 probably with age. Both Chun and Pfeffer stated that there are 

 four light organs on the eyeball in this species. Naef suggested four 

 but his illustration indicates two rows and more than that number of 

 organs. Sasaki stated that there are 15 photophores arranged 

 irregularly around the eye. In the specimens from the Albatross all 

 but one have 14 organs around the eyeball, 6 around the iris, and 8 

 on the periphery of the bulbus. Only in poorly preserved specimens 

 is there any irregularity of arrangement. Apparently these light 

 organs are fewer in number in smaller specimens, although an exami- 

 nation of small specimens from the Florida Current and from the 

 Dana collections shows 14 light organs on all specimens. 



In the armature of the tentacular suckers there are also dissimilari- 

 ties. Sasaki illustrated the sucker ring of one of the large hand 

 suckers, which shows strong curved round teeth and a narrowed 

 aperture. In the present specimens the hand suckers have small, 

 sharply pointed triangular teeth, slightly larger on the distal borders, 

 all of about the same size, about 22 in number, and not at aU correspond- 

 ing to those on the hand suckers of Sasald's figure. 



Remarks. — The present specimens all came from two general areas 

 rather widely separated. Those from Dammai are from the inner or 

 Sulu Sea side of the Sulu Archipelago in from 224 to 268 fathoms 

 while those of the other group are from the area of the Verde Island 

 Passage along the southern coast of Luzon from the South China
