HARDWICKE'S SC lENC E-G OS SIP. 



NOTICES TO CORRESPONDENTS. 



E. LovETT.— Your specimen of fern was forwarded to a 

 good authority on such matters and returned with the remark 

 that nothing could be made of so small a fragment. Please 

 send a perfect frond if possible. 



J. Coi-soN.— The plant forwarded to us is an unflowered 

 specimen of Erica cinerea, whose flowers had been meta- 

 morphosed into tinted leaves. 



J. W. Jeans.— Your specimen is the common Centaury 

 (Erytlirium centauriiim). 



Dr. G. D. Beati.y.— Thanks for the slides, which arrived 

 safely. The staining is most beautiful ; we have seen nothing 

 to equal it. Article will appear next month. 



F. S. Sheldon. — For information as to the Ray Society 

 apply to the Secretary, Somerset House, London. 



Q V. G.— The fungi inclosed in match-box arrived in too 

 smashed a condition to be identified. 



H. A. S.— The " Epidemic," as you call it, which has set in 

 in your aquarium and killed your gold-fish, &C., is probably a 

 micro-fungus, called Achyla ■prolifera. There is no remedy, 

 and your best plan will be to clean out the glass. 



C. Wood.— The small insects inclosed in quill are bird-lice 

 {Mallophagu). 



C. F. G.— For description and figure of the cast of the 

 British gold coin sent, see Thomas Wright's "Celt, Roman, 

 and Saxon." Trichodectes is a genus of parasitic insects, 

 belonging to the family Mallnpliuga. Antenna; triarticulate; 

 tarsi with a single claw. All the species live only on mam- 

 malia. Eaematopina have tarsi uni-articulate, with snigle 

 arcuate claw ; parasitic on man and other animals. 



J. W. WiLi.MiK. — The head of the common sparrow with 

 elongated upper beak is a very remarkable specimen. 



H. P., Ashbourne.— ilM^acomniwTO palustre, Tortulafallax.— 

 R. B. 



R. R., Selkirk.— 1. Hypnwn sericsuni; 2. H. molluscum ; 

 .■?. Rhacomitrium lanugiiiosum; 4. Tortilla runills; 5. Fissideiis 

 adiantoides; 6. Hypnum denticuiatum.—R. B. 



J. Cooper.— The " scarlet substance " on the back of 

 Coltsfoot leaf is a micro-fungus called Coltsfoot Rust {Culeo- 

 sporium tussilnginis).— 'M. C. C. 



Dr. B. L.— Your specimen is Purcinen malvacennnn; there 

 is not the gelatinous element oi Podisoma.—M. C. C. 



CoBRiGKXDA.- For fig. l-.'f, p. 253, "Coelacanthus," read 

 " Acanthodes." Page 254, line 34, for "four, viz., one dorsal, 

 one pectoral, one ventral, and one anal," read, " six, viz., one 

 dorsal, two pectoral, two ventral, and one anal."— W. H. P. 



W. C— We are much obliged for your specimen of Roccelta 

 furiformis. 



T. Green.— Your packet of foraminiferons sand arrived 

 safely ; please accept our thanks for it. In the neighbourhood 

 of March we have some of the most recent of post-glacial 

 marine sands, of which we believe the bed containing the 

 foraminifera to be a member. Consult Professor Williamson's 

 " Monograph of British Foraminifera." The commonest of 

 the fossil forms appears to be Rotalina. 



M. J. MuRTON.— It would seem as if the bo.x were attacked 

 with the fungus known as " Dry Rot" {Merulius luchrymans). 

 The only way to arrest its ravages is by applying corrosive 

 sublimate, or a solution of zinc. 



W. Bradley.- The "Fairy Circles" occupied by fungi 

 which you describe are probably caused by the Marasmms 

 oreades. See " Half-Hours hi the Green Lanes," p. 318. 

 Cardials eriophoriis, although not a common plant, is not to 

 be considered rare. It grows in Suffolk in several places 

 rather plentifully. Carduus nutans is a common plant.
