SULCATOR A REN A RI US.

Mr. Albany Hancock has paid considerable attention 
to the furrows made by this creature, and described them 
in a paper entitled “ On certain Vermiform Fossils in 
the Mountain Limestone Districts of the North of Eng- 
land,” published in the “ Transactions of the Tyne-side 
Naturalist’s Field Club,” which was read at the British 
Association at Leeds in 1858. 
The animal appears to be a very sluggish creature, 
since Infusoria attach themselves to the hairs of the na- 
tatory appendages. 
In colour the animal resembles the sand in which it 
lives, and may readily be passed without recognition. 
Mr. Gordon states that the eyes were cream-coloured in 
the specimen which he found. We believe, on the con- 
trary, that those which w r e took on the coast of Glamor- 
gan had dark, if not black, eyes. 
Specimens of this species in the British Museum were 
taken in the neighbourhood of Falmouth by Dr. Leach. 
It has been sent to us from the Moray Frith, having 
been picked up at Lossiemouth, on the sand from which 
the tide had just receded, by the Rev. Geo. Gordon; 
also from the coast of Northumberland, where it was 
found by Mr. Albany Hancock. 
The specimen from which our figure was taken we 
took, in company with Mr. Matthew Moggridge and Mr. 
J. Gwyn Jeffreys, in Oxwich Bay, and we have also 
found it in Rhosilly Bay in Glamorgan.
