Key to Species of Leandrites<br />
1. Rostrum nearly straight, overreaching antennal scale little if at all 2<br />
Rostrum curved somewhat dorsad, distinctly overreaching antennal scale .... 3<br />

separated on carapace posterior to level of posterior margin of<br />
orbit, and 4-7 (usually 4) teeth extending over major part of<br />
ventral margin; 2nd pereopods overreaching antennal scale by<br />
length of chela and fully '/2 of carpus; maximum carapace<br />
