Qaleolaria australis — material examined. 



The question of the possible identity of the tropical Indo-Pacific 

 australis with the boreal Atlantic biloba Sars has been discussed fully 

 in my report on the eastern tropical Pacific collection (19116). 

 According to Moser (1913) the two are identical. The present speci- 

 mens agree very well with the eastern Pacific representatives. The 

 length of the somatocyst varies a good deal — it is always short, 

 reduced to a mere bubble in some, and in a few of the most frag- 

 mentary ones none is to be seen. But in these its absence is only 

 the result of mutilation. 



I was in hopes that this large series would throw some light on the 

 question of the identity of G. chuni of Lens and Van Riemsdijk, re- 

 sembling australis, except for a much longer somatocyst, which I 

 referred provisionally to the synonymy of the latter. But none of 

 the specimens approach the chuni type. According to Moser (1913) 

 chuni is distinct, but she does not state the difference.

These two nectophores are in fair condition and show the complex 

 basal structure which I have described elsewhere (Bigelow, 1911&, 

 p. 239). The small somatocyst in conjunction with a prominent 

 dorsal and two lateral teeth and two ventral wings distinguishes the 

 superior nectophore, while the inferior one is characterized by similar 

 teeth and a single undivided ventrobasal wing.
