Sertularia gracilis. — Hassall. — This delicate zoophyte I got 

 first on the Norfolk coast in 1826, and again in Cornwall from 

 deep water. Specimens from both localities I sent to Dr. 

 Johnston, when he was publishing his 2nd edition of British 

 Zoophytes, and at page 67 he mentions it as "a very pretty and 

 delicate variety" . . . owing "its delicacy to the circumstance 

 of growing in deep water." Of its being a good species I never 

 had a doubt, but quietly bowed to authority. When, in 1868, 

 Hincks's "History of British Zoophytes" came out, I was 

 pleased to find at page 262, on the authority of Hassall, that it 

 was described as a new species, and figured at plate 53, fig. 2. 

 He has also noticed it in his "Catalogue of the Zoophytes of 

 South Devon and South Cornwall" at page 12, as "of much 

 slenderer habit " than that of Sertularia pumila ; his specimens 

 were from Torbay, mine were got off the Deadman, and is now 

 first added as a species to yoiu" list. Unfortunately I have not 

 a Cornish specimen by me, but have much pleasure in sending 

 for your Museum, a portion of the one I first got in Norfolk, half 

 a centurij ago. It is very pretty, and if examined under the 

 microscope, its delicacy and a peculiar twisting or fold, where the 

 internodes taper off below, may be seen well marked in the 

 specimen sent. I also send a small but characteristic specimen 

 of Sertularia pumila to compare with ^S'. gracilis. 



Plumularia siliquosa — Hincks, see Magazine of Natural History, 

 vol. XIX., No. 110 Hincks has figured and described this very 

 delicate species. His came from Guernsey. 



As may be seen by the specimen sent with this, I got it off 

 Goran Haven, 8th December, 1843, and sent specimens to Dr. 

 Johnston, these he has noticed in his 2nd edition of British
