C. porosus s. hiporcatus.âThe premaxillo-maxillary suture on the palate does not form a transAcrse line, but is W-shaped, and extends backwards as in the rest of the species of Crocodiles to be described. This Indian species is easily recognised by the prominent longitudinal ridge which extends in front of each eye, over the prefrontal bones, and by the absence of sub-occipital scutes. The nuchal scutes consist of four large ones, which form a square, and one or two smaller scutes on each side. The dorsal shield con- tains four to eight principal longitudinal rows. The digits, webs, and the serrated fringe of the legs are like those of C. palustris. Tlie head and snout, however, are distinctly longer, and more slender in proportion, and the adult has only four teeth in each premaxilla.

Specimens 01 15 to 20 feet in length are not uncommon, and there is a record of one monster of 33 feet. Consequently this is, both in bulk and lengtli, undoubtedly the largest species of recent reptiles. It is an inhabitant of tidal waters or estuaries, frequently entering salt water and going out to sea. Herewi
