On the linked page the Latin name is given as Cucumis melo L. This is a casaba melon. It is a melon within the melo species which are also known as muskmelons. Here are the sources of my great wisdom:
Thank you all, yes the scientific name is "cucumis melo" as it is written under my picture I linked above. But I want you native people to tell me if you go to a supermarket or I don't know a fruit shop and you want to buy such thing, what word would you use? Since it is not probably a common fruit there, so you may call it melon or a long melon in the market.
Thank you master! Such a great offer! What a big chance I missed before considering such an effort to learn the language. Your way should have been pretty much easier. No matter what the way is, the result is the melon! ;-)
