A CORNISH FAUNA. 



in which I have observed a close affinity of our own Crustacea with 

 those of the antipodal seas. 



Sulcatob arenaeius. — Sandfurrow maker. — Spence Bate, Bate 

 and Westwood, vol. 1, p. 189. 



I first found this species on the coast of South "Wales, on sandy- 

 shores between the tide marks, but I found afterwards that un- 

 described specimens had been in the collection of the British 

 Museum, which had been taken by Dr. Leach in the neighbour- 

 hood of Falmouth. 



The late Mr. Albany Hancock has paid considerable attention 

 to the furrows made by this creature, and described them in a 

 paper " On the vermiform fossils in the mountain limestone dis- 

 tricts of the North of England," published in the " Transactions 

 of the Tyneside Nat. Field Club."

Cephalon anteriorly produced. First two pairs of legs feeble, 

 imperfectly subch elate. Most of the points of the legs developed 

 like scales.

 Cephalon produced anteriorly. First two pairs of legs smaller 

 than the succeeding, and subchelate. The portion of the animal 

 that supports the swimming legs (pleon) lies generally closely 

 compressed beneath the sterrunt of the anterior portion.

This species was first taken on the shores of Banff by the well- 

 known naturalist, Mr. Edward, and afterwards on the shores of 

 Cornwall, where it was found off Polperro by Mr. Loughrin. 

 These last were as white as writing paper, and in this respect 

 differed from those received from the Moray Frith, which were 

 of a brown hue. After having been kept for a short time the 

 Cornish specimens assumed the colour of those from the Moray 

 Firth. Hence we may assume that white is their colour while alive. 

 Mr. Loughrin says that his specimens were procured either from
