अन्वयः

मे for me, शोकार्तस्य born out of sorrow (of slain bird), प्रवृत्त: came out without effort, पादबद्ध: consisting of four lines, अक्षरसम: each of equal number of syllables, तन्त्रीलयसमन्वित: with rhythm tuned to the accompaniment of stringed instruments, श्लोक: sloka, भवतु let it take a form, अन्यथा न not otherwise.

M N Dutt

This speech that I have uttered is of equal bound with metre and accents; it has rhythm and is capable of being chanted according to measure to stringed accompaniment. Let it therefore go forth as a sloka!

Summary

"Occasioned by the griefstricken (state of the bird) and composed in rhymed lines each of equal number of syllables tuned to the accompaniment of stringed instruments, let it be known as a sloka and not by any other name".
