PROCEEDINGS, 
(Phalacro corns herrisi ) from the G-allapagos Islands ; the okapi 
(Ocapia johnstoni), a large ruminant until recently unknown ; 
and the isabelline coloured form of the Cape hunting dog 
(.Lycaon pictus), a creature which, associated in flocks, runs 
down the larger African antelopes, and is perhaps able to 
maintain for any distance a greater speed than any other 
quadruped. 
The Museum contains a large number of white varieties and 
abnormally coloured mammals and birds, particularly of grouse 
and grouse hybrids. 
Among the British birds attention was called to the cirl- 
bunting ( Emberiza cirlus), an ally of the familiar yellow- 
hammer, a bird of very local occurrence in Britain, but not 
uncommon on the Chiltern Hills ; and the Dartford warbler 
(,Sylvia undata), one of our most interesting song-birds, never 
abundant in this country and now banished by the rapacity of 
bird-catchers and collectors from many of its former haunts. 
It used to nest on Stanmore Common, and is said to have been 
seen a few years ago among the furze-bushes on one of the 
Hertfordshire commons. 
After glancing over some of the collections formed for the 
study of the specialist, and inspecting the extensive library in 
its new building, a vote of thanks was accorded to Mr. Rothschild 
and Hr. Hartert for their kindness in receiving the members 
and exhibiting and explaining the collections. 
In returning to Tring Station after tea at the “ Rose and 
Crown,” the bee-orchis ( Ophrys apifera), the pyramidal orchis 
{Orchis pyramidalis), and other wild flowers, were observed by 
the canal bank, and the graceful pink flowers of the flowering 
rush {Butomus umbellatus) were seen in the canal near the 
station. 
Field Meeting, 24th July, 1909. 
NORTHWOOD AND CROXLEY GREEN. 
This meeting was held in conjunction with the Geologists’ 
Association and under the direction of Mr. Henry Kidner, 
F.G.S., who has furnished a very full report from which the 
following account is condensed. 
The members of the Geologists’ Association first examined 
a section of the London Clay with its basement-bed exposed in 
a brickfield at Horthwood. Proceeding to Rickmansworth they 
were met at the gravel-pits in Long Valley Wood by members 
of our Society, the object being to examine an outlier of the 
Reading Beds recently discovered in digging the gravel. 
Extending horizontally for upwards of 100 feet is a section 
showing, in descending order, greenish sandy clay streaked with 
brown, 1J ft.; bedded black and grey flint-pebbles with greenish 
sandy clay, 2 ft. ; bedded flint-pebbles with brown sand, red in 
parts, 1 ft. ; and brown sand with scattered black flint-pebbles,
