tionship of the genus. The Diphyid appearance of the pyramidal nectophore is 

 nothing more than an instance of parallehsm. And the same is true of the 

 Diphyid form of the nectosac. The apical prolongation of the latter above the 

 level of the pedicular canal is a concomitant of the alterations of the general 

 external form, not an indication of relationship to Diphyinae. 



There is no trace of an inferior nectophore, nor of any reserve bud which 

 might foreshadow such a structure. The appendages are represented by several 

 small buds, and a single definitive siphon with tentacles and very immature bract. 

 The latter structure has been described by Lens and Van Riemsdijk as scale-like. 



Galeolariinae Chun, 1,897. 



GALEOLARIA Blaixville, 1834. 



Galeolaria, the only kn nvn genus of the Galeolariinae, sometimes, though 

 wrongly, credited to Lesueur, was proposed by Blainville in 1S30, but must date 

 from 1834, when one of its species was first described. In the same year, 1834, 

 Quoy and Gaimard described two species, one of them being described also and 

 figured by Blainville. The genus is usuallj' credited to Bla'nville and the two 

 species to Quoy and Gaimard, and nothing would be gained by changing this 

 arrangement. 



We must first consider the species listed by Blainville in his second diag- 

 nosis ('34) of the genus, since it is one of these which must be taken as the type. 

 They are G. australis Quoy and Gaimard, G. quadridentata Quoy and Gaimard, 

 G. rissoi, and G. bilobaia, but the last two are manuscript names of Lesueur, 

 and have no standing. 



Chun ('97b, p. 16) mentions australis and quadridentata merely as "zwei 

 obere Schwimmglocken aus dem Indischen Ocean," but Haeckel ('88b) recognized 

 their importance. G. quadridentata was figured by Quoy and Gaimard ('34); 

 and their Diphyes quinquedentata was probably its posterior nectophore. The 

 conformation of the base of both nectophores approaches in complexity that of 

 G. monoica Chun. But it differs so much from the latter in the number and 

 arrangement of the basal teeth that it can not be identified with it, or with any 

 other actual species. G. quadridentata must still, and perhaps always, remain a 

 doubtful form. 



Galeolaria australis (Quoy and Gaimard, '34, pi. ;3, fig. 29,' 30, 31) was very 



' Fig. 29 is given by Quoy and Gaimard as " Diphyes quiitquedeiUiUa," but there are two figures 

 numbered 29, and tlie internal evidence of the figures themselves shows tliat one is auslralis, the other 

 Diphyes quinquedentata.
