or among the fibres of the nest of the mollusc 

 Lima Mans ; and then only one or two could be 

 obtained when carefully searched for, or more fre- 

 quently none at all. I may remark that although 

 got plentifully at the time above referred to, the 

 stones have at other times been examined without 

 any being found. A few were floated out from dry 

 mud that was dredged in 35 to 40 fathoms between 

 Cumbrae and Kilchattan. Taken also at Weymouth 

 by Professor Williamson. 



MUNNA KROYERI, Goodsir. 



Munna Kroyeri, Goodsir, Edin. New Phil. Jour., 

 xxxiii. (1842), p. 365, t. 6, f. 6. 



Habitat. — Taken among the fibres of the nest of 

 Lima Mans, Cumbrae. This species seems to be 

 much rarer here than Manna Whiteana; perhaps 

 it may be that the habitat of M. Kroyeri is less 

 accessible. It has been taken in the Firth of Forth 

 by Mr. Goodsir, and at Cullercoats and Seaham by 

 the Rev. A. M. Norman.

Habitat. — Taken on stones at low-water, Portloy, 

 (umbrae. Dredged at the mouth of Loch Fyne in 

 40 to 60 fathoms, inside a sponge ; and on a piece of 

 coal dredged off Dunoon in 13 fathoms, bottom mud 

 and gravel. When taken they often want their 

 terminal stylets, a circumstance which at first sight- 

 is apt to mislead. This species has also been taken 

 off the coast of Devonshire by Montagu ; Polperro,
