EUDOXOIDES. 59 



Leuckart (Z. U., p. 69), has conclusively shown that his Eudoxia campanula is the 

 Diphyozooid of his Dijjhi/es acuminata. But I can find no distinction between E. campanula 

 and E. Lessonii, and I have already endeavoured to prove that Biphyes acuminata is identical 

 with D. appendiculata. Consequently, Eudoxia Lessonii must be regarded as one of the 

 synonyms of the latter species, and the other ^«(/oa;z> are probably nothing but Diphyozooids 

 of other species of Bipliyes. 



Eudoxia Bojani {Eschscholz). PI. Ill, fig. 7. 



This species, of which I only obtained one specimen, is distinguished by the more 

 flattened form and symmetrically oval outline of the hydrophyllium, whose margin is 

 produced into a point on each side, at about the janction of the lower with the two upper 

 thirds. The inferior edge is convex and rounded, not truncated. 



In the sole specimen obtained the phyllocyst, broad at the base, was very short and 

 irregular. I suspect that it had undergone some abnormal alteration. 



The calyx is greatly elongated, and its edges smooth. 



The gonocalyces, which in the present instance were male, were subcylindrical, smooth, 

 and rounded, without those strong crests so cliaracteristic of the preceding species. 



Length of the hydrophyllium, three sixteenths of an inch. 



This species agrees so well with the figure and description of E. Bojani given by 

 Eschscholz, that, notwithstanding one or two minor differences, such as the lateral points 

 of the hydrophylHum, which Eschscholz does not notice, I feel justified in supposing it to 

 be the same. It was taken on the southern coast of New Guinea. 



Genus EUDOXOIDES (nov. gen.) 

 Diphyozooids derived from 



The hydrophyllium is elongated and pointed, flattened on one face, evenly convex on the 

 other, and is provided with a deep conical cavity for the polypite. Phyllocyst simply conical. 



EUDOXOIDES SAGITTATA. PI. IV, fiff. 1. 



I have seen only four specimens of the hydrophyllium of this species, and each of these 

 was devoid of a calyx, and had only imperfectly developed tentacles and reproductive organs. 

 Nevertheless, the form of the hydrophyllium is so peculiar that I am compelled to distinguish 

 it generically from other Diphyozooids. It is narrow and pointed superiorly, and its anterior 

 face is flat, the inferior angles of this face being pointed and well defined. The conical cavity 

 in which the polypite is lodged occupies rather less than half the length of the piece, and
