(S.) b2:  It also signifies ما تدحرج من القدر: [so in the L and TA: but the following verse, cited as an ex. of this signification, suggests that القدر is probably a mistranscription for القُرْدِ or القُرُدِ, i. e. “ ticks; ”to which, in several different stages of growth, the Arabs apply different appellations: (see حَمْنَانٌ:) and this is rendered more probable by the fact that, in the L, د and ر are often written almost exactly alike: if so, the meaning is (assumed tropical:)  A round tick; or a tick that has become round: likened, I suppose, to the little ball of dung above mentioned:] pl. as above: En-Nábighah  says, أَضْحَتُ يُنَفِّرُهَا الوِلْدَانُ مِنْ سَبَأٍكَأَنَّهُمْ تَحْتَ دَفَّيْهَا دَحَارِيجُ [app. describing a she-camel, and meaning, She became so that the children of Seba scared her away, as though they were round ticks biting her beneath her two sides].
