is not elided after a word denoting a part of the body (with the exception of mūrdhan and mastaka) before every word other than kāma,
Thus कण्ठे कालोऽस्य = कण्ठेकालः, उरसिलोमा, उदरेमणिः ॥ But मूर्धशिखः, मस्तकशिखः, मुखे कामोऽस्य = मुखकामः ॥ When the first member does not denote the name of a part of the body, the rule does not apply: as अक्षशौण्डः, nor does it apply when the first member does not end in a consonant or अ, as अंगुलित्राणः, जङ्घावलिः ॥,
