(TA.) -A3- Also [The mother-of-pearl shell; or oyster-shell; and any shell of a mollusk: and, by an extension of its primary application, the oyster itself; and any shell-fish, or testaceous mollusk of the water, and likewise of the land: ] the cover of the pearl; (K;) or this is called صَدَفُ الدُّرَّةِ, (S, O,) or صَدَفُ الدُّرِّ; (Msb;) a kind of cover created in the sea, composed of [ what are termed ] صَدَفَتَانِ [i. e. a pair of shell-valves ], which are opened from [i. e. so as to disclose ] a kind of flesh in which is life, called the مَحَارَة [i. e. oyster ], and in the like thereof are found pearls; (Lth, TA;) i. q. مَحَارٌ [which means oyster-shells, and also oysters themselves, and both of these may be here meant, as both are correct meanings of صَدَفٌ]: (M:) n. un. with ة: (S, M, O, Msb, K:) [in the Msb it is also said that الصَّدَفَةُ signifies the مَحَارَة, which is the مَحْمِل of the pilgrims; but I think that this is a mistake, caused by understanding مَحَارَة here in a wrong sense; for I find no other authority for assigning this meaning to الصَّدَفَةُ:] pl. أَصْدَافٌ. (O, K.) [See an ex. of the pl. voce حَلَزُونٌ.] ― -b2- [Hence,] الصَّدَفَةُ signifies also, (M, TA,) or صَدَفَةُ الأُذُنِ, (O,) The مَحَارَة [or concha, i. e. the external, deep, and wide, cavity, around the hole, ] of the ear.

[And in like manner, The two sockets in the scapula, in each of which turns the head of one of the two upper arm-bones: (see حَارِقَةٌ:) or these, it seems, are called by some الصَّدَفَانِ; for it is said that] الصَّدَفُ signifies the part of the scapula which is the place of the وَابِلَة.
