BIGELOW: MEDUSAE AND SIPHONOPHORAE. 419 



These specimens agree, even to such minor details as the relative 

 size of dorsolateral and basolateral teeth, with the Pacific collections 

 which I have studied (1911b, 1913). 



Galcolaria monolca is easily identified by the presence of three basal 

 teeth (two large lateral and one narrow dorsal) and two ventral wings 

 in the anterior, three dorsal teeth with incised tips, and an undivided 

 basal wing, in the inferior nectophore.

Galeolaria australis was taken at Stations 10,161, 10,162, 10,163, 

 10,166, 10,169, 10,176, 10,178, 10,186, 10,194, 10,196, 10,197, 10,200, 

 10,203, 10,207, 10,212; both on the surface, and in intermediate hauls. 

 The material consists of about thirty superior and thirty inferior 

 nectophores, some of them in excellent condition. 



The total absence of basal teeth in both nectophores, combined with 

 the presence of two ventrobasal wings in the superior, one in the 

 inferior, nectophore, make this the most easily recognized species of 

 Galeolaria. 



In my earlier discussion (1911b), I suggested that the Indo-Pacific 

 G. australis, and the Atlantic G. biloba, Sars, would prove to be identi- 

 cal, hesitating to unite them definitely only for want of material from 

 the Atlantic. According to Moser (1913a) they are identical. And 

 the Bache specimens listed above corroborate this view, for I have 

 been unable to find any distinction between them and series from the 

 North and South Pacific (1911b, 1913).
