ZOOLOGY. 



Cyclisticus convexus in County Down. 



I took lately two specimens of this rare woodlouse on the sea-shore at 

 Bangor, Co. Down. It has only been taken in Ireland previously in 

 Counties Dublin, Fermanagh, and Carlow, having been found on all 

 three occasions by Dr. Scharff.

A New Irish Amphipod. 



In a paper " On some Freshwater Amphipods : the Reduction of the 

 Eye in a new Gammarid from Ireland" {Sitzb. Konigl. Bokm. Geselisch. 

 d. IVissen., 1905, and Ann. Mag. Nat. Hist, (7), xx., 1907, pp. 227-245, 

 pis. xi.,-xii.), Prof. F. Vejdovsky describes four specimens from Lough 

 Mask, with vestigial eyes and pigment, referred by Mr. Kane to Niphargus 

 kochianus, as a new genus and species, Bathyonyx de Vismesi. The new 

 genus is intermediate in character between Gammarus and Crangoiiyx, 

 and, in the opinion of the author, furnishes "excellent evidence as to 

 the probable first stage in the degeneration of the eyes." The omnia- 

 tidia are in a reduced condition, not forming a compact compound eye, 

 but " loosely scattered under the hypodermis." 



Recent captures of Irish Crustacea. 



I have lately taken Gammarus Duabeni in L> Erne, near Castle Archdale, 

 and in D- Mask ; Gammarus campy lops in D- Conn, and Mysis relicta in 

 h. Ree and the Shannon at Portumna.

Miscellaneous Captures of Lepidoptera in Ireland, 



The following were taken at L,ambay at the close of May, the weather 

 being extremely cold, which pi evented much success : — 



Micropteryx calthella, Xylopoda fabriciana, Clepsis rusticana, Cnephasia mus- 

 atlana, Plutella maculipennis (abundant) Eupacilia maculosana (abundant), 

 Gelechia ericetella (abundant). The rather local geometer Panagra petraria 

 was fairly numerous on the eastern half of the island. At Castle 

 Archdale, County Fermanagh, I was fortunate enough to meet with the 

 rare Eupithecia logata.
