FAUNISTIC NOTES. 165 



passing through Bolt Tail ; and the third includes the off-shore grounds 

 between Bolt Head and the Start, where gravel, broken shell, and 

 soft rock predominate. Each of these three principal regions is, of 

 course, capable of considerable further sub-division, but an account of 

 these, with their inhabitants, must be postponed. 



It may be well, however, to give some notes on a few of the rarer 

 animals found, or of those which have not previously been taken by the 

 Marine Biological Association at Plymouth. 



Paraphellia expansa, Haddon. Three or four specimens of this 

 interesting anemone were dredged, on August IGth, in about 26 

 fathoms, at a distance of 3 miles N. W. of the Eddystone. The 

 surface was covered with fine particles of gravel. One of the 

 specimens is still alive in the Laboratory. This species, for which 

 a new genus was formed, was first obtained by Haddon at the mouth 

 of Bantry Bay, in a depth of 40 fathoms, and was described from 

 two specimens — one obtained in 1885, and a second in the following 

 year.* Specimens have since been obtained by Prof. Herdman from 

 near the Isle of Man.f 



Sarcodictyon catenata, Forbes. The red variety was common on shelly 

 grounds, both round the Eddystone and off Prawl Point. 



Heteroconlyle conyhcarci, Allman. Four colonies of this rare hydroid 

 were dredged near the East Eutts, on August 30th. The species was 

 identified by Mr. E. T. Browne, to whom the following note is due : — 

 Each colony was on a large shell of Buccinum undatum, inhabited by 

 the common Hermit Crab, Eupagiirus hcrnhardus. The colonies corre- 

 spond to the description given by Allman. There was no difficulty in 

 identifying the species as the gonophores, each with a single ovum, were 

 present in large numbers upon the blastostyles. This hydroid was first 

 taken by Allman in Glengariff Harbour, Bantry Bay, and afterwards by 

 Hincks at Oban, which are, I believe, the only localities where it has 

 been found. 



Of the other Hydroids, Thuiaria articulata, Pallas, and Diphasia 

 tamarisca, Linn., are worthy of mention. 



Ophiadis hcdli, Thompson, was abundant around the Eddystone, and 

 especially so off Prawl Point. Ophiura affinis was also taken at the 

 latter place, and a single specimen of Echiyiocardium pennatifidum, 

 Norman, was dredged from a bottom of broken shell, about 5 miles 

 south of Bolt Head. 



Polyyordius sp. occurred in numbers in gravel and broken shell 

 dredged off Prawl I*oint (34 fms.), and a few were also taken from a 

 ground of fine broken shell (20 fms.) south of the Eddystone.
