were observed hauging from the incision which separates the marginal 

 lappets. It was not observed — on account of the poor preservation of 

 this region of the bell — how many tentacles and how many sense-bodies 

 there are in Ephyroides. I think from what I could observe that there 

 are eight tentacles and eight sense-bodies on a specimen with 3*2 radial 

 socles. This is, however, conjectural, and was not observed, as the figures 

 show. The structure of the subumbral region of the disk is in all cases 

 too distorted to admit of a scientific examination. 



Family LIXERGID^, Hteckel, 1877. 

 LiNERGES Mercuritjs, Hgeckel. 



There is no doubt that when the Gulf Stream is more carefully ex- 

 ])lored Linerges will be found in great abundance. I have taken it by 

 thousands in the Straits of Florida, and the Albatross collected many 

 specimens from the Gulf of Mexico and the Caribbean Sea. It also 

 occurs in the Sargasso Sea, at Bermuda, and off Florida. 



Thedifierent species of iyi»er</e.9 recorded by Ilseckel seem to me based 

 on doubtful specific characters. Of the bottle full of specimens of 

 Linerges from the Gulf of Mexico some have characters of L. Mercurms, 

 others of L. Pegasus, while there is a complete series of individuals 

 which forms a graded series from one into the other. If the two species 

 are good ones both may be expected in the southern part of the Gulf 

 Stream.

Aijrelia PLAViDULA, Per. et Les. 



These two specimens closely resemble A. JJnrirhda, but have very 

 long oral arms, and in the position and size of the "ovarian openings" 

 seem to stand intermediate between A. marginalis^ Ag., axi^ A. flavidula. 

 One of the specimens is an interesting one in having only three oral 

 arms and three ovarian openings.
