nearly meeting. The caudal appendages have their 
branches nearly equal, whilst the last has the base pro- 
duced into a sharp point at the upper distal extremity. 
The terminal scale is lanceolate. 
We have not been able to determine the colour of this 
species, which is the largest of the genus, not having 
seen any living or fresh specimens. The surface of the 
skin is irregularly covered with very small sharp hairs, 
so minute that they can only be detected by a high 
power of the microscope. This species is nearly as 
large again as either of the others, and its geographical 
range is also considerable. 
We have received specimens from our valued friend 
and correspondent, Mr. Geo. Barlee, who has taken them 
with the dredge at St. Ives, on the north coast of Corn- 
wall, and also from the Shetland Islands. We have also 
received it from the coast of Northumberland, from 
the Rev. A. M. Norman. It also occurs, not uncom- 
monly, in Berwick Bay, whence we received specimens 
many years since from the late lamented Dr. George 
Johnstone. 
Beneath is a sketch of Whitby Rocks, on the coast of 
Northumberland, from the clever pencil of Miss M. 
Hancock.
