shelly bottom, Strangford Lough, Mr. Hyndman. Cork, Mr. Humphreys. 
December 16th, 1850. In the stomach of a haddock taken at Newcastle, 
Co. Down, I found a perfect small specimen of this species and another 
broken one. Off Bray, Dr. Ball. 
Genus Brissus. 
B. lyrifer, Forbes. 
Of this species — discovered by Professor E. Forbes in the Clyde, in 1840 
— a few individuals were obtained off the South-West coast of Ireland by 
Mr. M ‘Andrew. To use this gentleman’s words, “ One or two specimens 
were brought up from a depth of forty fathoms off Cork and off Cape 
Clear, and from thirty fathoms in Bantry Bay, near Great Bear Island. I 
have found it a frequent inhabitant of muddy bottoms in from 12 to 100 
fathoms.” 
Genus Amphidotus. 
A. cordatus, Penn. 
Of general occurrence ; is thrown ashore on the beach at Newcastle in 
quantity, so much so, as sometimes to look like a row of round frothy 
balls sent in before the advancing tide. 
A. roseus, Forbes. 
Not so generally distributed.

Genus Psolus. 
P . phantapus, Linn. 
In September, 1835, I obtained by the dredge a single specimen at 
Bangor, County of Down. 
Genus Cucumaria. 
C. pentactes, Mull. 
Among a quantity of marine productions dredged in Belfast Bay, by 
my friend Edmund Getty, Esq., and kindly sent to me, was an injured 
specimen 2 inches in length, apparently of this species. I can now an- 
nounce the species with certainty, Dr. Drummond having procured an 
example of it when dredging at Bangor in June, 1839. Several specimens 
dredged in 15 to 30 fathoms in Bantry Bay, Mr. M‘ Andrew. 
C. communis , Forbes and Goodsir. 
North of Ireland, W. T. Youghal, Dr. Ball. Roundstone, Mr. 
M‘Calla. 
C. fusiformis, Forbes and Goodsir, Brit. Echin., p. 219. 
This species has already been enumerated in my report on the Inverte- 
brata of Ireland, but no particulars respecting it have been published. 
The specimen there alluded to was dredged in 10 fathom water, at 
Donaghadee, by Dr. J. L. Drummond, in the summer of 1843.
