Mountain range also echoes peripherally (5)
I believe the answer is:
andes
'mountain range' is the definition.
(Andes is an example)
'also echoes peripherally' is the wordplay.
'also' becomes 'and' (I've seen this before).
'peripherally' suggests removing the centre (only the 'peripheral' letters in the word are kept).
'echoes' with its middle removed is 'es'.
'and'+'es'='ANDES'
(Other definitions for andes that I've seen before include "South American mountain chain" , "Mountains for the Danes, oddly" , "Peak District" , "Mountains of 6 dn" , "danes found in mountains" .)
