and white Centaury flourish abundantly. The latter ground is also pro- 

 ductive of great variation in the colouring of Prunella vulgaris (Self-heal), 

 of which, besides specimens of the ordinary purple hue, large quantities 

 of white, marjoram-pink, and faint lavender- tinted blossoms, may be 

 gathered every year. — C. B, MoFFAT, Ballyhyland, Co. Wexford. 



White Bug-Ie (Ajuga reptans)« This summer I counted fourteen 

 plants of Ajuga reptavs, all bearing white flowers, under one tree, in a wood 

 at Ballyhyland. Within this circumscribed space I saw no spike whose 

 flowers were of the normal colour. The ground, though shaded, was not 

 perceptibly more so than throughout the rest of the wood, where the 

 Ajuga is uniformly blue. — C. B. MoffaT.

Crustacea from Upper Lough Erne arsd Lough Corrib. The 



following list of species captured by me in Upper Lough Brne, in the 

 3^ears 1886-88 may be of interest. Several of them were identified by 

 Professor G. S. Brady: — The Phyllopods comprised — Daj^hnia pulex com- 

 mon near the shores ; D. galcata, on two occasions at surface in centre of 

 lake, when the sun was shining; Sida crystallina, common in the bays, 

 especially amongst the weeds, often adhering to lower surface of leaves of 

 water-lilies, etc. ; Leptodora hyalina, common; BythotrcpMs sp. taken in large 

 %■ numbers at the surface in centre of lake, on a hot afternoon in August, 

 4 1886 : it was then so plentiful that a tumbler dipped in the lake would 

 bring up three or four specimens. I have since obtained it on other oc- 

 casions, but never in such profusion ; Bosmina coregoni. The Copepods 

 were — Cyclops coronatus, Diaptomas castor, Tenura velox, and Argulus foUaceus, 

 the last very common, both free-swimming and on perch, etc. Ponto- 

 porcia ajinis represents the Amphipods; two specimens only were found 

 amongst weeds in a sheltered bay; the importance of this form (together 

 with Gammarus neglectus and Mysis oculata, var. relicta^ lies in their being 

 looked upon as relics of an old marine fauna. I have heard that Mysis 

 occurs in Lough Neagh. If any reader of the Irish Naturalist comes 

 across it, I should be extremely obliged for specimens. 



From the "Proceedings of the Dublin Microscopic Club," reported in 

 Quarterly Journal of Microscopic Science, vol. xii., we learn that Mr. Arthur 

 Andrews found the following species in Lough Corrib : — Pholyphemus pe- 

 diculus, on one occasion whilst fishing in Lough Corrib with a small 

 muslin net, hundreds were taken at a single dip in a sheltered sunny 

 creek, while further search along the same shore failed in procuring 

 a single specimen ; Lynceus elongatus, Sida crystallina, Daphnia mucronata, 

 and Acantholehris curvirostris, Lilly, {acanthoceocus, Scholl.), plentiful in 

 most small bog pools. Lynceus elongatus and Bosmina longirostris are 

 reported from Clonhugh lake, near Mullingar. — R. N. CrEIGhTon, Bally- 

 shannon, Co. Donegal.

Lepidoptera at Armagh.— Last year I picked up a larva of Lo- 

 phopteryx camelina on oak, and a fine specimen emerged last May. From 

 Mr. Halbert's note, Irish Naturalist, vol. i., p. 195, I see that it has hitherto 

 only been recorded from the south. It may interest him to know that I 

 took Zanclognatha grisealis here in 1889, vide Ent. Monthly Mag. (2) vol. i. 

 p. 140. In August Melanthia ocellata flew into my house, and on Septem- 

 ber 23rd, I saw a specimen of Vanessa atalanta flying up the road. It was 

 remarkable that this butterfly and V. cardui should appear here this year, 

 for it has been about as bad a year as possible for Lepidoptera. I took a 

 specimen of Stigmanota regiana in June sitting on the wall of the Cathedral. 

 Fcroneoe were very scarce. I got only one P. perplexana, and a couple of 

 P. variegana. Besides these, the only captures worth mentioning are A71-
