On a stone taken tip by a fisherman’s hook from deep 
water. It seems to he unknown, and I have therefor 1 ' 
given it the name as above. . 
The Serpulaceae appear to be of rapid growth, and at p 1 ’® 
to be destitute of a shell. I have seen specimens of /’ 
Heteroelite species, probably Spirorbis Ileteroclita, 
the newly formed shell, though of full size, so transpare 11 ’ 
that the fine vessels and fibrils of the animal might be e* 
antined through its substance. 
BALANUS RUGOSUS. Mont. Test. Brit., vol. 1, p- 
Scarcely uncommon, though local. 
A question of doubt (?) should be added to Tubicine 
Clavata. in 
ANATIFERA FASCICULARIS. After a storm ^ 
October, 1841, T found on the beach a small empty pm' 
bottle, with this barnacle attached to its neck ; and J> J 
Peach informes me that numerous feathers of a bird "’ el ^ 
at the same time washed on shore, having attached 
them, specimens of A. Fascicularis and A. Sulcata: P r0 ° f 
of the fact that these rare species are capable of attach' » 
themselves to substances which have never been deep ( 
immersed. The first named of these species though co" 
roonly appearing almost sessile, is capable of elong* l J ® 
its pedicle to about the length of the shell, and of mo' 1 0 
it in various directions. 
A. ANSERIFERA. Mr. Peach found this species a

Local, but scarcely uncommon. I have found sev e 
specimens in an undisturbed part of my garden. . p 
SIGARETUS TENTACULATUS? a single sped®

Among the Radiate Animals the Cornish Fauna rcp° e 
21 species of Echinodermata ; but the list will require s °' ,, 
correction, and must then be left with the omission of 3 ' ^ 
unascertained species of Holothuriadas. 
added are : 
ECHINUS MILIARIS. Forbes 
p. 161. Common. 
SPATANGUS PURPUREUS. Forbes, p. 182. 
uncommon. 
LUIDIA FRAGILISSIMA. Forbes, p. 135. From 3 
water, scarcely common.
