It is difficult, as in the C tenc- brosus, to distinguish the costal folds. There are not more than twelve. The tail is short and stout; its upper edge is much compressed, as is the posterior half; its glandular structures are much less developed than in other specfes of Amblystoma, the crypts of the crest being minute and globular. Length of tail equal from its origin (posterior margin vent) to posterior outline of sternum. The extremities are very stout, just meeting when laid along the side. The palms and soles are very wide, and the toes short and flattened. They stand, as regards length, behind, 3, 4, 2, 5, 1; before, 3, 2, 4, 1 4 G 6 Fio. 23.
