8. apicata (Amphinema apicatum. Hseckel) ; the other, the IHnematella, 

 Fewkes. Both of these have in the adult condition an apical promi- 

 nence on the bell, which in the former is without internal cavity, and in 

 the latter with a cavity. Stomatoca periphylla, Hseckel, is destitute of 

 this prominence, is much larger, and the stomach is situated on an espe- 

 cial " Magenstiel." In this species the mouth lappets, stomach with 

 sexual bodies, lie outside the bell cavity. The specimens agree substan- 

 tially with Hseckel's description, except that the tentacular bulbs at 

 the base of the tentacles are more swollen than he represents in his 

 figure (PI. iv, fig. 10, Das System der Medusen). It is probable from the 

 studies of Ilincks, Allman, and Hseckel that the young of this species 

 has for its hydroid a genus related to or identical with Perigonimvs. 

 This notice is the first record of S.periphylla, from the Western Atlantic. 



Family GERYONID^E, Eschscholtz. 



LlRIOPE SCUTIGERA, McO. 



Family CUNANTHID^E, Hseckel. 



CUNINA ? 



Among the Narcomedusse there are a few specimens of a Cunina-lika 

 medusa which is temporarily referred to this genus. The specimen 

 was so mutilated that it was impossible to tell whether it was a Gunina 

 or a Solmaris, although from the character of the festoon canal and the 

 existence of gastral pouches, it seems more closely allied to the former 

 genus. It was not possible to see the gastral pouches, one of the main 

 characters of the Cuninida 1 , in several of the specimens, although they 

 are well seen in one of the same. 



Specimens era mined.
