Rev. Mil. Landsborougii's List of Zoophyi 



8. Hippotiioa. Laraour. 



1. Hippothoa catenularia. The Hippothoao are very beautiful, but 

 very minute, and therefore little apt to be observed by unpractised eyes. 

 This species, though the most common, is rare here. I have, however, 

 found it mi shells. It seems to be pretty common on Pinnae from Coll 

 and Tiree. 



2. H. divaricata. This elegant little zoophyte has been got, though 

 rarely, OH Phyllophora rubens, here and in Cumbrae. I have got it also on 

 Pinnoo from Coll and Tiree. It is synonimous with H. lanceolata. 



9. Gemellaria. Savigny. 

 1. Gemellaria loriculata. Goat -of -mail coralline, and synonimous 

 with Notamia loriculata. I have never found the smallest fragment of 

 this on the coast of Ayrshire, or in Arran ; but when, in 1846, 1 visited the 

 Little Ross Island, near Kirkcudbright, I got as many specimens floating 

 in a quarter of an hour as will supply my friends for many days to come. 



Family. — Celleporidce. 

 10. Cellepora. 0. Fabricius. 



1. Cellepora pumicosa. This is one of our most common corallines, on 

 other corallines or seaweeds. 



2. C. ramidosa. I am not sure that I have got this pretty branching 

 coralline here, but I have got it from Cumbrae, and I have dredged it in 

 Lamlash bay. The fine specimens are about two inches in height, and 

 branched somewhat like an antler. It is found attached to old shells 

 from deep water. 



11. Lepralia. Johnston. 



This is sea-scurf, a pretty tribe, in which there is much variety. 



1. Lepralia hyalina. This is very common on the Ayrshire coast, and 

 also in Arran and Cumbrae. It is found most frequently on Laminaria 

 saccharina, but it is found also on shells and other algae. The variety 

 with the punctured cells is not uncommon with us. 



2. Lepralia Ilassallii. This I found on Patella coerulea, on the shore 

 at Saltcoats, and sent to Dr. Johnston, as new to me, and it seems that it 

 has turned out to be L. Ilassallii. 



3. L. tenuis. This I have never seen, but it has been got within my 

 range, having been dredged by Mr. Hyndman, off Sana Island, near the 

 south end of Kintyre. 



4. L. simplex. The same may be said of this, which has been dredged 

 by Mr. Hyndman off the Mull. 



5. L. ventricosa. Do. do. do. 



6. L. Hyndmannii. Do. do. do. 



7. L. granifera. This I found on the Ayrshire and Arran coasts, on 

 old shells. 



8. L. Landsboromi. Dr. Johnston has done me the honour of dedi-
