1194 Insects. 



as the visits of this species may be regarded as uncertain, and made frequently at dis- 

 tant intervals, I think it right to offer any occurrence of this singular bird to the re- 

 cords of your journal. One point I would beg to call your attention to, and it is that 

 there appears to be a migrational movement of this species at this period of the autumn, 

 probably from Holland, where they breed; for I observe that the flock of eleven which 

 I reported to you as having been seen in this neighbourhood in 1843 (Zool. 364), were 

 first seen on the 13th of October, in that year. — Edward Hearle Rodd ; Penzance,

Hearing of Fishes. I noticed a circumstance the other day, that seems to me to 

 go far to prove that some fish at least do not possess the sense of hearing. I was fish- 

 ing during a rowing-match ; it was a sunny clay, and there was a shoal of bleak near 

 the surface of the water, and though some small cannon on an island about four hun- 

 dred yards from the spot were repeatedly discharged at intervals, they took not the 

 slightest notice, and I caught one in the midst of the firing. — Geo. Guyon ; Rich-

Correction and addition to Mr. King's Note on Mollusca, {Zool. 1039). I was sorry 

 to find, on receiving the August number of ' The Zoologist,' that a mistake had been 

 made (I suppose by my own inadvertence) in the name of one of the mollusks of which 

 I forwarded to you an account, as found in Cornwall. The species of Arion which I 

 found was not A. hortensis, but A. ater. It is very common in this neighbourhood, 

 but I have not yet found any of the black colour. If they are all to be reckoned vari- 

 eties of A. ater, it is curious that in this neighbourhood every variety of colour should 

 be found, except that which may be considered typical. I have much pleasure in add- 

 ing to the list Zonites pygmaeus and Pisidium obtusale. Of the former I have found 

 but one specimen, in a wood under Polwhele, near Truro. The latter I have found in 

 several situations, near Truro ; and in a turf-pit at the foot of Tregeal Down (near 

 Launceston), where they were very abundant : also at St. Stephsn's, near Launceston, 

 where, in a boggy place, I fonnd them clinging to the stones which I raised from the 

 water. This species appears to live very little under the mud. I would notice also 

 the abundanee of Pisidium amnicum in the Exe, near Exeter. My sieve or scoop 

 will hold about a quart of mud, and in the proceeds of one scoop I counted upwards 

 of forty. At the same scoop I obtained a specimen of P. pulchellum ; and in a small 

 pond adjacent, I obtained a specimen of P. obtusale. — Robt. L. King ; Grammar-

Captures of Lepidopterous Insects at Lewisham. 



Cnephasia Ictericana, July 4 to 11, among grass, in abundance, in our own fields. 

 I had never before met with it. 



Cnephasia Longana, one, July 4, one, July 5, one, July 6, one, July 19, among 

 grass. This I had not taken at Lewisham before.
