Diagnosis

J. C. Merriam 1906L. mollis differs from L. douglassi in its larger size and propor- tionally larger M1 and M2 (fig. 5); from L. vulpinus it differs in its smaller and lower crowned premolars; from L. gregorii it differs in its wider palate, backward direct- ed, more robust, and salient paroccipital process, in larger and lower crowned P3, in more robust P4 with relatively larger and more anteriorly situated protocone and proportionally larger M1 with more prominent cingulum and slightly stronger para- style, and in proportionally larger M2 that bears a metaconule.
