The Vélodrome Buffalo and Stade Buffalo were cycling tracks in Paris.

Ōhāriu, previously styled Ohariu and then Ōhariu, is a New Zealand parliamentary electorate returning one Member of Parliament to the House of Representatives.
 It first existed from 1978 to 1993, and was recreated for the 2008 election.
 In 2008, it was the successor to Ohariu-Belmont , first contested at the first mixed-member proportional (MMP) election in 1996.
 Through its existence Ohariu-Belmont was represented by Peter Dunne, leader of the United Future party.
 Dunne contested and won the recreated electorate in 2008.
 He announced on 21 August 2017, he will not be seeking re-election in the 2017 general election.
Yehud had been a province of the Neo-Babylonian Empire since the suppression of the Judean rebellion in 585/6 BCE.
 It first existed as a Jewish administrative division of the Neo-Babylonian Empire under Gedaliah, though it quickly became depopulated after his murder and another unsuccessful revolt around 581/2 BCE.
 The province was absorbed into the Achaemenid Empire with the collapse of the Neo-Babylonian Empire in 539 BCE.
Carpolestes is a genus of extinct primate-like mammals from the late Paleocene of North America.
 It first existed around 58 million years ago.
 The three species of "Carpolestes" appear to form a lineage, with the earliest occurring species, "C. dubius", ancestral to the type species, "C. nigridens", which, in turn, was ancestral to the most recently occurring species, "C. simpsoni".
 It had flattened fingernails on its feet but with claws on its fingers.
 Morphologically it supports Robert Sussman´s theory of the co-evolution of tropical fruiting Angiosperms and early primates where Angiosperms provide nectar and fruits in return for dispersing the seed for tropical rainforest plans.
 It appears to have been a distant relative of the Plesiadapiforms such as Plesiadapis.
The Whitefish Bay National Forest Scenic Byway is a National Forest Scenic Byway that runs along Whitefish Bay in the Hiawatha National Forest in the U.S. state of Michigan.
 The byway mostly follows Federal Forest Highway 42 (FFH 42) through Chippewa County in the Upper Peninsula.
 As a forest highway, it is maintained jointly by the Chippewa County Road Commission (CCRC) and the U.S. Forest Service (USFS).
 The route of the byway first existed as an earth road by the 1930s; it was improved into a gravel road in the 1940s and paved between the 1950s and the 1980s.
 The byway designation was created in 1989.
Dynastes hyllus is a large scarab beetle species that ranges from Mexico to Guatemala.
 Its larvae have been found to associate with the logs of "Persea americana".
East Grinstead was a parliamentary constituency in the Kingdom of England, the Kingdom of Great Britain, and the United Kingdom.
 It first existed as a Parliamentary borough from 1307, returning two Members of Parliament to the House of Commons elected by the bloc vote system.
 The borough was disfranchised under the Reform Act 1832, but the name was revived at the 1885 election when the Redistribution of Seats Act created a new single-member county division of the same name.
The avocado ("Persea americana") is a tree long thought to have originated in South Central Mexico, classified as a member of the flowering plant family Lauraceae.
 Recent archaeological research produced evidence that the avocado was present in Peru as long as 8,000 to 15,000 years ago.
 Avocado (also alligator pear) refers to the tree's fruit, which is botanically a large berry containing a single large seed.
New Windsor College was the name of two colleges located in New Windsor, Maryland.
 The first existed from 1843 until 1851.
 The old location of that college was taken over by Calvert College.
