ROSACEA PLICATA. 201 



14 mm. long, only one very small bud for a reserve nectophore is to be seen 

 (Plate 2, fig. 3) but in another specimen in which only one full grown nectophore 

 is present, there is a reserve bell of considerable size. 



The single nectophore observed by Huxley, evidently the younger of the 

 two definitive ones because part of the stem was attached, is included in the 

 present species, because it has the long hydroecium characteristic of P. 

 cymbiforviis. The only records of P. cymbiformis from the Indo-Pacific region 

 are from the Indian Ocean and from Torres Straits (Huxley), from the Malay- 

 sian region (Lens and Van Riemsdijk) from the coast of Lower California 

 (Gravier), besides the present series from the Eastern Tropical Pacific. These 

 few, however, are sufficient to show its wide distribution, and taken in connec- 

 tion with its known occurrence in the Mediterranean and in the Atlantic indi- 

 cate that it may be expected to occur throughout the warmer regions of the 

 three great oceans.

In none of the specimens was anything but the basal end of the stem with 

 a few small buds preserved. The nectophores were all separated. Those 

 listed above as belonging together are united on the strength of being taken 

 together, and since this species was comparatively rare throughout the area 

 traversed, it is probable that the association is natural. Thej^ are easily dis-
