6. Scrobicularia. A single shell, almost perfect, which I found 

 at Port Carlisle, seems to indicate the presence of S. pipevata, Gm. in 

 a living state somewhere near Bowness. 



7. Top-Shells [Trochus zizyphinus, H.) At present I know only 

 of this one species, sparingly represented. I have taken it occasionally 

 dead at Silloth. 



8. Periwinkle. On the woodwork near the Silloth Harbour the 

 oviparous species (Littorina littorea, L.) lays its eggs freely; and I have 

 bred some in captivity. In the same locality the flat-topped species 

 (L. obtusata, H .) is plentiful, as is also the vivaparous (L. mdis, Maton.) 

 I have also found the shells of one or other species at Port Carlisle, 

 Bowness, and again to the south of Silloth. 



9. Hydrobia. I once thought the Rissoas and Hydrobias were 

 quite absent from the Cumbrian coast, but by carefully preserving some 

 seaweed in salt-water, I have been able to rear several specimens of 

 at least one species (H. ulvce, Penn.) It is however, too early at pre- 

 sent to say whether all belong to this type ; or what other, and 

 more minute species may yet be discovered. 



10. Turritella. Walking from Bowness-on-Solway to Port 

 Carlisle, I recently found several specimens of this shell, of which 

 there is but one British species, (T. terebra, L.) All were dead, but the 

 condition of the shells indicated a not very distant habitat. 



It is absurd to suppose that this list of species at all fairly re- 

 presents the marine molluscan fauna of the Solway Firth; but though 

 I know almost every inch of the coast from Carlisle to Workington, 

 I have given all the information which I at present possess on the sub- 

 ject, in the hope that someone who has the leisure will take the matter 

 up in good earnest, and make out a perfect list of species for the use 

 of other investigators. 



P.S. March 20th, 1890. I allow the foregoing record to stand 

 unaltered as representing the exact state of our knowledge up till the 

 end of 1889. I have, however, been able, owing to the frequent gales 

 which have recently prevailed, to collect a large quantity of material 

 by means of which this list will at least be trebled in my next com- 

 munication. H. F.
