have seen from the original locality in Sweden^ have, upon examination, 

 proved to comprise exceedingly small, though fully matured, specimens 

 of Pisidiurn hibernicum and P. nitidum. This form of P. kibernicum 

 much more nearly fits the original description than does the species now 

 bearing the name parvuliim ', while the accompanying specimens of 

 P. nitidum resemble a very small form of the variety which I have des- 

 cribed as var. crassa {Journal of Conchol i^y, vol. xv., 1918, p. 2Q'>). It 

 seems possible therefore that when the matter is cleared up the name 

 parvulum will have to be dropped.

Pollan in Lough Ree. 



On March 22nd of this year I found on the shore of Lough Ree a 

 half-killed Pollan, presumably Coreqonus pollan, commonly called the 

 " Fresh water herring." The gulls had pecked her eyes out, a female 

 fish about i lb. in weight. It is the only specimen I have seen from this 

 lake, and the net fishermen I have spoken to say that they have never 

 caught one.

Hoopoe in Innishowen. 



On 28th April Mr. J. A. Johnston captured a Hoopoe {Upupa epops 

 Linnaeus) whose wing had been slightly injured by a shot, near Cam- 

 donagh, Co. Donegal. It was in good plumage and he kept it until 2nd 

 May, feeding it on bread and milk and supplying it with fresh sods. 

 During his absence from home the bird escaped,

Incubation of Birds. 



In reply to Mrs. Rait Kerr (July, 1918), last year I watched a nest 

 of Ringed Plover {Aegialitis hiaticola) ; the fourth egg was laid on May 

 26th and the young were all out on June 19th — 24 days. This year 

 with the same birds the fourth egg was laid on 21st April, and the young 

 made their appearance on 14th May — 24 days. All the egg chips are 

 removed immediately.
