this species having first been recorded from Hatfield Park, Essex; and
the second and third British record for _Agaricus (Clytocybe) Sadleri_
(Ashridge Park and Cassiobury Park). The very rare _Strombilomyces
strombilaceus_ has been found in Grove Park, Watford, and the still
rarer _Peziza luteo-nitens_ on the Chalk slopes between Aldbury and
Ashridge Park. Lastly it may be mentioned that Mr. Saunders added the
"myxie" _Physarum citrinum_ to the British fungus-flora from specimens
found by him at Caddington and Welwyn.

_The Birds_ of Hertfordshire have been carefully observed, and the
appearance of rare visitors has been duly recorded. At a lecture
delivered at St. Albans in 1902, Mr. Alan F. Crossman, F.L.S., F.Z.S.,
stated that 212 species had been known to visit the county, and
mentioned, _inter alia_, that the kingfisher is more numerous in
Hertfordshire than formerly, that the heron nested in the county for the
first time in 1901, and that the appearance of the bearded titmouse had
been noticed on but three occasions. During the last forty years the
following birds, among others, have been noticed as occasional
visitants: the storm-petrel (_Procellaria pelagica_), golden oriole
(_Oriolus galbula_), whooper-swan (_Cygnus musicus_), snow-bunting
(_Plectrophanes nivalis_), greater spotted woodpecker (_Picus major_),
black tern (_Hydrochelidon nigra_), great northern diver (_Colymbus
glacialis_), herring-gull (_Larus argentatus_), cormorant
(_Phalacrocorax carbo_), tufted duck (_Fuligula cristata_), hoopoe
(_Upopa epops_), crossbill (_Loxia curvirostra_), sheldrake (_Tadorna
cornuta_), Guillemot[d] (_Lornvia troile_), Pallas' sandgrouse (_Syrrhaptes
paradoxus_), rock thrush (_Monticola saxatilis_), black redstart
(_Ruticilla titys_), Dartford warbler (_Silvia undata_), grasshopper
warbler (_Locustella nævia_)[d], waxwing (_Ampelis garrulus_), twite
(_Linota flavirostris_), hen harrier (_Circus cyaneus_), buzzard (_Buteo
