bills, which however is usually black-tij^ped when the bird is very 

 young ; and I have one with the train which has a considerable por- 

 tion of its beak black. 



181 a. Ardea lepida is now and then shot in this part of Bengal, 

 but I have not yet procured a specimen, Mr. Jerdon has obtained 

 it in Southern India. 



188. Argala capillata (.''). I did not see a single example of this 

 species during the late season for these birds. 



201, 202. These I have before expressed my presumptive opinion 

 to be Charadrius Geoffroyi and C. Leschenaultii. I have forwarded 

 specimens of both to the India-house. 



206. Himantopus asiaticus of Lesson. It appears never to have 

 the black cap of H. melanopterus . 



209. This appears to be the Totanus stagnatilis. 



220 b. Mr. Jerdon has obtained the Calidris arenaria ; he also gets 

 Numenius phceopus, which I have not yet seen here ; and his oyster- 

 catcher is the Hcematopus longirostris, which I have likewise received 

 from Arracan. 



234, 235. Are male and young female of the same species, which 

 is also the Gallinula plumbea of Vieillot. 



241 a. Two species of flamingoes occur here, the Phcenicopterus 

 antiquorum, Tem., more rarely, and the P. minor. I have had a fine 

 series prepared of both. 



263. Plotiis VaiUantli. A bird of this species was brought to me 

 some time ago, weak from want of food, caused by its having swal- 

 lowed, or, I should rather say, attempted to swallow, a small Silu- 

 roid (^Bagrus teugara), which had erected its pectoral spines and thus 

 pierced the throat of the bird, the spines of the fish projecting on 

 either side through the skin of its captor. 



265. I have lately procured several specimens of both species of 

 pelican mentioned. 



266 a. Rhynchops flavirostris. Now and then observed upon the 

 river opposite Calcutta, skimming and ploughing the surface of the 

 water.

XIX. — Observations on Ehrenber(f s De Mycetogenesi Epistola, ^c. 



By Arthur Hill Hassall, Esq. 

 In the ' Annals and Magazine of Natural History ' for November 

 1842 the following editorial remark occurs, appended to a notice of 

 a paper read by me before the Microscopical Society of London, and 

 entitled " An Explanation of the Cause of the rapid Decay of many 

 Fruits, more especially of those of the Apple Tribe :" — 



" Complete observations on this interesting subject have been made 



known by Professor Ehrenberg so far back as 1820 in the ' Re- 



gensburger Flora,' ii. p. 535, and more fully in the ' Nova Acta 



Nat. Cur.' vol. x,, imder the title • De Mycetogenesi Epistola.' " 



A repetition of the substance of the same observation, affixed to a 



paper on the Influence of Fungi in the Production of Disease-, in-
