Appendices to the Fifth Annual Report 



Found in ditches by the side of Loch Ascog, near Rothesay, and in 

 Loch Eadd. 



I at first supposed this to be specifically distinct, but further research 

 convinces me that it must be looked upon as a variety of C. virens, inter- 

 mediate forms between it and the type being not uncommon. 



Cypris Broivniana, Jones. 



Jones, Entomostraca of the Tertiary Formation, p. 13, pi. i. fig. la, 

 lb, and fig. 2a, 2b. 



Shell ovate, excessively tumid, height and width equal to two-thirds 

 of the length : seen from the side subreniform, highest in the middle * 

 extremities well rounded, dorsal margin boldly arched, ventral straight ; 

 seen from above the outline is elliptical, scarcely narrower in front than 

 behind. Colour ashy grey, clouded, surface smooth. Length, l-30th of 

 an inch. 



Found in pools by the side of Loch Fadd. 



Judging simply from the figures given by Professor Rupert Jones in his 

 excellent monograph of the Tertiary Entomostraca, it would seem that 

 the so-called variety tumida, may probably be only the young condition 

 of the type Browniana. The recent specimens agree in size with the 

 typical form, but in contour are more like the variety. This is one of 

 the most interesting " finds " among the fresh-water Ostracoda.
