Shells prevent their eggs from drying out. Scales prevent water loss and protect them. The circulatory systems is associated with lungs for breathing air. Internal fertilization allows for reproduction on land.
Hard shelled or leathery eggs that can incubate/hatch outside of water, allowing them to migrate dry areas. Skin that prevents transpiration, allowing them to live on land without dehydrating. These would be primary...the third could be any of a number of adaptations, changes in locomotion, eye sight et cetera
Not all reptiles dwell on land. Some of them live in the water, such as crocodiles, marine iguanas and sea snakes. Even these reptiles must come to land sometimes, to bask, or lay eggs.

Some reptiles live in water and some live on land. Take a snake for example, some live in water, some live on land, and some live in both. I think a reptile can live in both and some can not because most reptile have lungs or some have gills.
Some of the adaptations that allow fish to live in the water are gills, fins, and scales. The gills allow the fish to live in the water. The gills allow the fish to extract oxygen from the water. The fins allow the fish to swim through the water and help it stear itself. For the scales I'm not sure!

Well they can, but they can also live on land.

An animal that is able to live both on land and in water is classified as "amphibious."
Reptiles need land too. Fish do not.

on land and sometimes in the water
A crab is one of the species that are classified as crustaceans. Crabs are commonly found in most shores in the tropics as they have adaptations that allow them to live on land.
