Reptiloid Race for Labyrinth Lord

A small idea which just came to me while musing on the possibilities of an "anything goes" mashup D&D setting. I've actually never come across a playable lizard-like race in D&D before.

Reptiloids are members of various reptilian humanoid races. They are typically of average human height and build, with scaly skin of varying hue (often greenish).

Reptiloids are strictly carnivorous, and have a natural bite attack which causes 1d6 damage. They have a very powerful sense of smell, which means that they are only surprised on a roll of 1.

Reptiloids have a natural armour class of 7, due to their scales, and gain a +4 bonus to saves versus poison.

Four types of reptiloid are described below.

Gullygug: Not strictly a reptile, but close enough, gullygugs are a race of amphibious frog-men. When lightly encumbered they can swim at their full movement rate. They can make a hop attack, jumping up to 15' forwards and gaining +1 to-hit and +2 damage if using an impaling weapon. Gullygugs can breathe underwater for 10 minutes. In dry environments gullygugs suffer -2 to-hit unless they have a source of water available to wet their skin.

Lizard-man: A brutish and cruel race of scaly humanoids, with the heads and tails of lizards. Their jaws are especially strong, and inflict 1d8+1 damage.

Snake-man: An only vaguely humanoid race, with a long serpent body and tail in place of legs, a snake's head, and human-like arms. They may attack with their tail, attempting to coil around an opponent. Constricted opponents suffer 1d3 damage per round and -2 to-hit. A snake-man's tail also allows him to coil around pillars and such. Due to their unusual form, snake-men cannot wear normal humanoid armour, and must pay double when purchasing armour.

Troglodyte: A slimy subterranean race. When unclothed, their chameleon skin enables them to surprise on a 1-4. They can also choose to exude a stench which causes sickness (-2 to attack rolls) in other humanoid races within 30', unless a save versus poison is made. Note that a troglodyte's stench affects all humanoids (except other troglodytes) within range, including allies.
