 1896. Cydocypris serena, B. aiidisr., /. c, Part II, (Appendix) p. 718. 



A common and widely distributed species. It has been 

 found in Loch a Chroin, at an altitude of 2500 feet, by Mr 

 Evans. 



5. Cydocypris Icevis (0. F. Miiller). 



1896. Cydocypris kevis, Brady and Norman, /. c. , Part II. (Appendix) 

 p. 718. 



This, which is not such a common species as the last, has 

 an elliptical instead of an ovate form when looked at from 

 above. It has been observed in Duddingston Loch, Loch- 

 gelly Loch, pools on Luffness Links, etc. 



Dr G. W. Miiller appears to think that the species referred 

 by G. S. Brady and ISTorman to Cydocypris serena, Koch, is 

 the true C. Icevis of 0. F, Mtiller, and that their C. Icevis 

 is probably identical with a form described by Croneberg 

 under the name of Cydocypris pygmcea}

Hob. — Abundant in pools in the brickfield at Portobello in 

 the autumn of 1888. In pools on May Island in September 

 1890. Common in pools on the side of the Union Canal at 



^ Scottia Browniana (Jones), which up till 1887, when living specimens 

 were obtained near Rothesay, was only known as a fossil, was collected in a 

 post-Tertiary deposit at Elie, Fifeshire. by the late James Bennie of the 

 Geological Survey (cf. Proc. Roy. Phys. Soc. Edin., vol. x. pp. 339-341, 

 1890-91). This form, which is placed between Cydocypris and Cypris, has 

 not yet been found living on the east side of Scotland.
