3. Busxra, Alder. 
B. nitens, Alder. 
Dredged in Salcombe Bay, on Calicella dumosa. 
[Filey, Yorkshire; Llandudno, North Wales. ] 
4, VaLKERIA, Fleming. 
1. V. Cuscuta, Linn. 
Not uncommon, in fide-pools, on Coralline and weed; Tor- 
quay ; near Plymouth, of remarkable size and beauty, &e. 
[Llandudno, on Halidrys; Filey; Ramsay, Isle of Man.] 
2. V. Uva, Linn. 
Common, under stones, on Corallines, Sertularia pumila, &e., 
between tide-marks. 
3. V. pustulosa, Ellis & Solander. 
Dredged abundantly in Salcombe Bay; ‘“ Fowey Harbour, 
and off Goran, Cornwall, very rare”? (Peach). 
This species grows in dense arborescent masses, and some- 
times attains the height of 4 inches. 
[Llandudno, North Wales; Filey.] 
4. V.tremula,n. sp. Pl. XII. fig. 9. 
Stem creeping; cells elongate, tapering to a point below, very 
small and slender. 
Saleombe Bay, on Flustra chartacea. 
This is a very minute species. It may be known at once by 
its delicate tapering cells, which terminate in a point below. 
They seem to be very slightly attached to the creeping stem, 
and droop a little to one side when the polypide retracts itself. 
I have met with what I take to be the same species on shell 
dredged off the Isle of Man. 
5. Mimose1xa, Hincks. 
M. gracilis, Hincks. Pl. XVI. fig. 1. 
Not rare in the Laminarian zone, always on Halidrys sili- 
quosa: Salcombe Bay; Torbay, under Berry Head; Plymouth ; 
* Polperro and Goran” (Couch). 
In the original description of this beautiful species (‘ Annals’ 
for November 1851) I have stated that the polypides are fur- 
nished with a gizzard. I'rom subsequent observation, however, 
I am inclined to doubt whether this is the case or not. The 
_ point must be reserved for future determination.
