A CORNISH FAIfNA. 
in -whicli I have observed a close affinity of our own Crustacea with 
those of the antipodal seas. 
StiLCATOR ARENARitrs. — Sandfurrow maker . — Spence Bate, Bate 
and West'wood, vol. 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.” 
Genus, Sulcatoe. — Spence Bate. 
An. Nat. ITist., vol. xii, p. 504, and vol. xix, p. 140 . — Bate and 
Westwood, p. 187. 
Cephalon anteriorly produced. First two pairs of legs feeble; 
imperfectly subchelate. Most of the points of the legs developed 
like scales. 
Dabwinia. — Spence Bate, Cat. Amps. Brit. Mas., p. 108 . — Bate 
and Westtoood, p. 182. 
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. 
Dabwinia compeessa. — Spence Bate, Cat. Brit. Mus., p. 108, 
. — Bate and Westwood, l.c., ml. i,p. 184. 
This species was first taken on the shores of Banff by the weU' 
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 resped 
differed from those received from the Moray Frith, which wer® 
of a brown hue. After having been kept for a short time the 
Cornish s^iecimens 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
