Statement I is correct because the class name Reptilia is derived from the Latin word 'repere' or 'reptum', which means to creep or crawl, referring to their mode of locomotion. Statement II is incorrect because while most reptiles have a three-chambered heart (two atria and one partially divided ventricle), crocodiles are an exception and possess a four-chambered heart.
