And the indentation between the latter is shallower than that between 

 each dorsal tooth and the lateral tooth which flanks it. As is usual 

 in Galeolaria, the teeth are triangular, with rounded, or very slightly 

 dilated, tips; the dorsal teeth deeper than the scale-like lateral teeth. 

 The ventral wings are much shorter than in G'. quadrhahis, G. atistralis, 

 or G. monoica, squarish in outline, each with a peculiar indentation of 

 its basal margin (Plate 8, fig. 2) ; and they are entirely separated along 

 the mid-line. 



The identity of the inferior nectophore listed above rests not only 

 on the fact that it was taken in the same haul as the superior one just 

 described (they were not attached), but on the fact that it agrees 

 perfectly with the inferior nectophores of two specimens of G. quadri- 

 deniata from Naples. I have not been able to find a single character 

 to separate the inferior nectophore of G. quadridcntata from that of 

 G. quadrivalvis, the former, like the latter, having four basal teeth, 

 and two large basal wings, with secondary flaps on their inner margins; 

 besides even showing the transverse constrictions formerly thought 

 diagnostic of the latter. 



The stem with all its appendages, has been lost in both Bache 

 specimens. In those from Naples (both females), in which it is well 

 preserved, the appendages closely resemble those of G. quadrivalvis 

 (1911b, pi. 5, figs. 5-7). 



The identification of these specimens as the G. quadridcntata of 

 Quoy and Gaimard, rests on the presence of the four basal teeth in 

 the superior nectophore, clearly shown in their figure, and described 

 by them as "quatre pointes" (1834, p. 45, pi. 5, fig. 32, 33). The 

 only difference is that the basal wings are shorter in our specimens 

 than in their figure. But this is not sufficient, as against the evidence 

 of the basal teeth, to warrant a new species, which would be necessary 

 were they not referred to G. quadridentata, for no other Galeolaria so 

 far described has four teeth in the superior nectophore. 



Galeolaria monoica (Chun).

This species was taken at Stations 10,161, 10,163, 10,166, 10,169, 

 10,176, 10,180, 10,186, 10,188, 10,196, 10,198, 10,200, both on the 

 surface and in intermediate hauls. The series consists of about 

 thirty superior and as many inferior nectophores.
