Question: What are sightings of the Galloway Puma, a  supposedly real British big cat, often reported as?

Context paragraphs:
Acinonyx: Acinonyx is a genus within the cat family.  The only living species of this genus, the cheetah, "A. jubatus", occurs and thrives in open grasslands of Africa and Asia.  Though often described as a big cat, this term is used primarily to describe cats of the "Panthera" genus, ruling the cheetah out as a big cat.

Galloway Puma: The Galloway Puma is a "phantom cat", a supposedly real big cat, which has been sighted numerous times throughout Dumfries and Galloway, in south-west Scotland.

Beast of Exmoor: There have been numerous reports of eyewitness sightings, however the official Exmoor National Park website lists the beast under "Traditions, Folklore, and Legends", and the BBC calls it "the famous-yet-elusive beast of Exmoor."  Sightings were first reported in the 1970s, although it became notorious in 1983, when a South Molton farmer claimed to have lost over 100 sheep in the space of three months, all of them apparently killed by violent throat injuries.  Descriptions of its coloration range from black to tan or dark grey.  It is possibly a cougar or black leopard which was released sometime in the 1960s or 1970s after a law was passed making it illegal for them to be kept in captivity outside zoos.  However, considering that cougar and leopard life spans are 12–15 years, this is unlikely.  In 2006 the British Big Cats Society reported that a skull found by a Devon farmer was that of a puma, however the Department for Environment, Food and Rural Affairs (Defra) states that "Based on the evidence, Defra does not believe that there are big cats living in the wild in England."

Momo the Monster: Momo is the name of a local legend, similar to the Bigfoot, which is reported to live in Missouri.  The name Momo is short for 'Missouri Monster' and it is reported to have a large, pumpkin-shaped head, with a furry body, and hair covering the eyes, which resembles a shag carpet.  First reported in 1971, near Louisiana, Missouri by Joan Mills and Mary Ryan, Momo was first reported up and down the Mississippi River with later sightings documented further west by travel of water ways.  It is supposedly a large, 7 ft tall, hairy, black, manlike creature that emits a terrible odor.  Some suggest it was a rogue American Indian.  Following sightings in 1972 beginning at 3:30 pm July 11, first reported by Terry, Wiley, and Doris Harrison, and lasting for about 2 weeks, tracks were found and submitted to Lawrence Curtis, director of the Oklahoma City Zoo and Botanical Garden.  He deemed the tracks to be that of an unknown primate species.

Big Cat Diary: Big Cat Diary, also known as Big Cat Week or Big Cat Live according to the format of the show, was a long-running nature documentary series on BBC television which follows the lives of African big cats in Kenya's Maasai Mara.  The first series, broadcast on BBC One in 1996, was developed and jointly produced by Keith Scholey, who would go on to become Head of the BBC's Natural History Unit.  Eight further series have followed, most recently "Big Cat Live", a live broadcast from the Mara in 2008.

Beast of Buchan: The Beast of Buchan is a big cat or phantom cat reportedly sighted mainly in the historic Buchan area of Aberdeenshire in northeastern Scotland.  Sightings throughout other areas of Scotland, stretching from the northern highlands down to the border with England, have also been claimed; the earliest reports date back to the 1930s.  The tales of the Buchan Beast are as well known as those of the Beast of Bodmin.

British big cats: British big cats, also referred to as ABCs (Alien, or Anomalous, Big Cats), phantom cats and mystery cats, are reports and incidents of Felidae not native to Britain but supposed to inhabit the British countryside.  These sightings are often reported as "panthers", "pumas", or "black cats".

Big Cat Records (U.S. record label): Big Cat Records is an Atlanta-based hip-hop record label distributed by Tommy Boy Records.  The label was founded in 1999 by Melvin "Mel-Man" Breeden and Marlon Rowe.  Big Cat Records is best known for the success of Gucci Mane, whose records on the label have sold over 1.5 million units.  Other artists with releases on Big Cat include Yung Ralph, Pretty Ricky, KHIA, Buju Banton, Maceo, Black Magic, Rasheeda, and Freekey Zekey.

Cougar: The cougar ("Puma concolor"), also commonly known as the mountain lion, puma, panther, or catamount, is a large felid of the subfamily Felinae native to the Americas.  Its range, from the Canadian Yukon to the southern Andes of South America, is the greatest of any large wild terrestrial mammal in the Western Hemisphere.  An adaptable, generalist species, the cougar is found in most American habitat types.  It is the second-heaviest cat in the New World, after the jaguar.  Secretive and largely solitary by nature, the cougar is properly considered both nocturnal and crepuscular, although there are daytime sightings.  The cougar is more closely related to smaller felines, including the domestic cat (subfamily Felinae), than to any species of subfamily Pantherinae, of which only the jaguar is native to the Americas.
