NOTE. 



Since the foregoing pages were in print I have received 

 from Messrs. Mulder and Trebilcock their paj^er (ui " Victorian 

 Hydroida, Part V.,"' from the " Geelong Naturalist," in which 

 reference is made to some of the sjDccies mentioned in the 

 present paper. One of the new forms described — Sertidarella 

 annulaventricosa — is almost certainly the same as 8. undulata 

 {ante, p. 284). Plumidaria setoceajormis, n. sp. is evidently 

 founded on a small specimen of P. procmnbens, Spencer. A 

 figure is given of " Hebella scandans," growing on Sertvluria 

 ungniculata as described herein (see H. calcarafa, var. contorta). 

 It is mentioned that hydrotheca? are borne on the primary 

 stolon where it crosses the nodes of the Sertularia, a feature 

 which I have not seen in my specimens. 



I have also received from Dr. Eraser his paper on " Some 

 Hydroids of the Vancouvei- Island Region, and Notes on 

 some Alaskan Hydroids." Halechim flexile, Allman, and 

 //. parvulmn. Bale, which, following Billard, I have united. 

 arc recorded by the writer as distinct species.
