Right Lateral View of Lesueur's Terrapin In my first article of this series of brief contributions on our native chelonians, a short account was presented of Bell's Terrapin of the genus Chrysemys. This group will be taken up again later, as it embraces many interesting species of wide distribution; for the present they are passed by, in that a more or less nearly related genus may be touched upon. This is the genus Malacoclemniys, which up to date is said to comprise some half a dozen species. Generally they are of good size, the largest forms attaining a length of a foot or more. Besides the' famous and very widely known Diamond- backed Terrapin (M. palustris), we have in this interesting assemblage such ele- gant types as the Geographic Terrapin (M. geographica) ; Kohn's Terrapin (M. kohnii) ; Maur's Terrapin (M. pulchra) ; Lesueur's Terrapin (M. lesu urii), and the Ocellated Terrapin (M. oculifera^. While these six species differ consider- ably, in some instances, do not depart so very much from certain species of the genera Chrysemys. Popularly, as in the case of the latter, they are known as "sliders," and they are sold in many of our markets under that name, a prominent contradistinction being seen in the "Dia- mond-back," large examples of which often sell at the stalls for no less than eight dollars. One of the species of this genus is but rarely seen away from its range, and that is Lesueur's Terrapin, listed above. Re- cently Mr. Edward S. Schmid has re- ceived a large consignment of these from
