836 NOTES AND MEMORANDA. 
The English Channel is not a recorded habitat for Virgularia so 
far as we know, except for this Hddystone specimen and a smaller 
fragment obtained off Falmouth in a former dredging excursion of 
the Birmingham Society in 1879. 
Coryphella smaragdina.—On Friday, May 11th, a small EKolid 
was dredged near the Asia buoy. On subsequent examination 
it proved to be Coryphella smaragdina, A. & H. Alder and Han- 
cock described the species from a single specimen found at Whitley, 
in Northumberland. It is also found in the Mediterranean. It 
is, therefore, curious that the species has hitherto never been found 
at Plymouth. The body of the specimen is about half an inch long 
and pure white in colour, the tentacles are equal in length, and the 
anterior angles of the foot are produced out into two tentacular-like 
processes. The branchiz are disposed in five transverse bands, and 
are a vivid green in colour. Though the specimen has been nearly 
a fortnight in spirit the green is as bright as when the animal was 
alive. Alder and Hancock in their description of the species 
mention that they found it on the common Fucus vesiculosus. They 
go on to say that ‘this position was most likely accidental; at least, 
it must not be taken as a proof that this species is less carnivorous 
than its congeners.” The Plymouth specimen was found crawling 
on a stone amongst a mass of Hydroids, so that Alder and Hancock’s 
surmise is fully borne out.—J. C. Sumyur.
