Charles H. Spurgeon on Psalms 44:19

Dragons. The word rendered dragons —(Mynt), tannim —means either a great fish, a sea monster, a serpent, a dragon, or a crocodile. It may also mean a jackal, a fox, or a wolf. De Wette renders it here jackals. The idea in the passage is essentially the same, whichever interpretation of the word is adopted. The "place of dragons" would denote the place where such monsters are found, or where they had their abode; that is to say, in desolate places, wastes, deserts, old ruins, depopulated towns. Albert Barnes.
