CLASSIFIED RESUME OF ORGANISMS OBSERVED 309 



String, with as many as thirty of the brown bodies, was 

 seen. No luminescence was observed. Locomotion was a 

 slow, steady advance. 



In the trawling nets salpae are rare compared with their 

 abundance near the surface in other localities, although 

 remains of several small individuals usually occur in every 

 net. 



Class ASCIDIACEA 



Order ascidiae luciae 



Pyrosoma colonies up to one foot in length were 

 observed a half dozen times, between 980 and 2000 feet. 

 All except one of these was completely aglow with tiny 

 pin-points of light. These organisms are rare in the 

 trawling nets, as usually only one small colony, several 

 inches in length, is caught for about every twenty nets 

 drawn. Occasionally, during certain months, the nets are 

 almost filled with long, rope-like colonies several feet in 

 length. 



Subphylum leptocardia 

 Order amphioxi 



Amphioxides was observed at iioo and again at 1503 

 feet on the last of the deep-sea dives. At least forty, of 

 mature size, were in the first group. The beam was going 

 full strength and I was focused on several unknown, 

 rounded organisms only about two feet from the window, 

 when this school suddenly came into focus. I thought for a
