Read the book in the late 60's.

The story is about a ship crashing on a planet. The passengers are made up of several different aliens. They all have in common telepathy. Each species with more or less telepathy strength. At the end of the story, its revealed that they are on good old earth.
I have been searching this book for years. Title or author would be appreciated.

Your description is pretty short on details, but there's a chance you're thinking of the short story "Specialist" by Robert Sheckley. If that's not it, try posting any concrete details you can recall.
