footnote, p. 214), and I have found the same form in Loch Tarff, 

 near Fort Augustus.

 recorded from a second Irish locality — Lough Mask — by Mr. 

 Kane (03).

 Br u instead, Norfolk (R. Gurney).

 species has been recorded from Scotland. 



Bosmina lonyirostris var. cornuta. Mr. J. Murray obtained this 

 last year at Crieff, in Perthshire, i.e. in the " Highland " region. 



Bosmina mixta Lilljeborg. Mr. Kane reports the occurrence 

 of this species from two additional Irish localities — L. Oughter 

 and L. Conn (63). 



Ilyocryptus agilis Kurz. This has been found in Scotland by 

 Mr. J. Murray, but the exact locality cannot be given until last 

 year's collections of the " Lake Survey " have been re-examined. 



Ilyocryptvs acutifrons Sars. This rare species has been found 

 by Mr. B. Gurney in Wroxham and Sutton Broads, Norfolk. 



Macrothrix laticornis (Jurine). Pond at Thorpe, and Waxham 

 Cut, Norfolk (R. Gurney). It has not previously been recorded 

 from the Broads district. 



Macrothrix hirsuticornis Norman & Brady. Some very fine 

 examples (one as much as y 1 ^" long) of this species have been 

 found by Mr. W. A. Cunnington at Cambridge. 



Alona eleyans Kurz. To the single record given in Part I. 

 may now be added, Pond at Brumstead, Norfolk, where it was 

 f aken in company with D. atkinsoni, by Mr. R. Gurney. 



Leydigia quadrangular is (Leydig). Mr. R. Gurney finds this 

 species fairly well distributed in the Broads district, though when 

 Part I. was issued I knew of no records for it in that locality. 



Alonella exigua (Lilljeborg), This species, as distinct from A. 

 excisa, has been obtained by Mr. R. Gurney, in Sutton, and 

 Wroxham Broads and Catfield Fen, Norfolk, and he has also 

 collected it in North Uist. 



Pleuroxus aduncus (Jurine). Although not included in Part I. 

 in the list of Cladocera of the Norfolk Broads, owing to the 

 absence of definite records, Mr. R. Gurney finds this species to be 

 the commonest of the genus in that area.
