In this genus the spawn consists of numerous waved 

 coils. When the tentacles are said to be four, it is to be 

 understood that the labial palpi are included, which are 

 here elongate and resemble in form the true tentacles ; the 

 tentacles are quite smooth, and the gills continuous and not 

 in clusters.

Ex. F. coronata, Forbes, pi. 66, fig. 1. 



The spawn in this group is of many coils. The body is 

 slender, and the buccal appendages or labial tentacles are 

 very long. The chief peculiarity, however, is in the tenta- 

 cles being annulate, and in the branchial lobes forming clus- 

 ters continuous over the back.
