FRESH-WATER CYCLOPID^ AND CALANID^. 25 



where it was taken by the Rev. Dr. Norman ; but I have re- 

 cently (1890) found it in Minstead Mill Dam, Hants. It has 

 not been noticed, so far as I know, by any other author since its 

 publication by Uljanin.

Mr. Thomas Scott has sent me specimens of this species from 

 Eaith Loch, Kirkcaldy, N.B. ; and Mr. Scourfield notes it from 

 Wanstead Park ; Cuckoo Pits, Chingford ; and the Eoyal Botanic 

 Gardens, Eegent's Park. These are the only localities which I 

 have to add to the list given in the Eay Society Monograph. 

 Though widely distributed it seems to be a scarce species. It has 

 been recorded from Norway (G. O. Sars) ; Sweden (Lilljeborg) ; 

 Germany (Koch, Fischer, Claus) ; Bohemia (Fric) ; Turkestan 

 (Uljanin) ; North America (Herrick).
