The sentence Are there any good ones left is an example of a reduced relative clause.
The Oxford Dictionary of English Grammar (p353) defines a reduced clause as:
a shortened clause, particularly a non-finite or verbless clause with
a postmodifying function that can be interpreted as a relative clause
with its relative pronoun and finite verb omitted, e.g.
- Anyone scared of heights is advised not to attempt to climb this
tower. (= Anyone who is scared of heights ...)
The general term for the omission of words that are recoverable by the listener or reader is ellipsis.
Note: Expanding the last sentence The items are eligible described below to include the pronoun and verb results in:
- The items are eligible which are described below.
The expansion is itself of dubious grammaticality. The original sentence is of certain ungrammaticality.
