Most of tlie specimens were young blastozooids (asexual form 

 with stolon), 1 to 3 mm. in length. Some had a few buds upon 

 the dorsal process. A large blastozooid with the adult wide 

 muscle bands was taken on September 21st. It measured 

 8^ mm. in length, and had a number of buds on the dorsal 

 process, which was about Ij^mm. in length. 



1897. A single specimen taken in July, and four in August 



and October.

Oikopleura (sp. ?). 



? Oihopleura flabellum, J. Miiller. 



? Oikopleura dioica, Fol. 



All the specimens, both " Valencia" and " Port Erin," seem 

 to belong to the one species; and that species is probably 

 what I call Oikopleura flalellum. Lohmann, in his recent 

 work on the Appendiculariidse, considers that 0. flahellum is a 

 synonym of Fol's 0. dioica. I cannot follow him in this. 

 Even if it be definitely proved that the two names represent 

 the same species, still flalellum, as a name, has priority 

 (J. Miiller, 1846) over dioica (Eol, 1872), and the latter must 

 lapse. 



[1895. Abundant during April and the early part of May. 

 Absent towards the end of May. 



1896. Common during July, August, and September; at times 



very abundant. Scarce in October.

early part of the year. Yery abundant in October. 

 A few seen during JN'ovember and December.
