SULCATOR ARENARIUS. 191 



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 aj)j)ears 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 we 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 Ghunorgan.
