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. Ofl' 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. 



ORDER, CIRRHI-VERMIGRADA. 

 Solothuriadce. 



Genus PsOLUS.

In September, 1835, I obtained by the dredge a single specimen at 

 Bangor, County of Down. 



Genus CucuMARlA. 

 C. pentactes, MiiU. 

 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.fusifonnis, Forbes and Goodsir, Brit. Ecliin., 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 di'edged in 10 fathom water, at 

 Donaghadee, by Dr. J. L. Drummond, in the summer of 1843.
