On the whole he adopted Mr. Waterhouse’s arrangement; but recog- nizing the fact that his four groups were of more than family value, he raised them to the rank of suborders. He also made several changes in the arrangement of the families and the position of some of the more doubtful forms, and imposed new names on all the divisions, which he arranged in the following order :— Glires. I. Sciuromorphi. 1. Sciuro'ides. II. Myomorphi. 2. Myoxoi'des. 3. CastoroYdes. 4. Sciurospalaco’idesi. 5. Myoides. 6. Spalacoi'des. 7. Dipodoi'des. III. Hystricornorphi. 8. Hystricoides. 9. Spalacopodo'ides§. 10. Eriomyo'Ydes||. 11. HemionychoYdes^f. IV. Lagomorpki. 12. Lagoi'des. Eleven years later Professor Lilljeborg published his admirable sys- tematic review of this order**. Appreciating the great importance of the characters which separate the Leporidae and Lagomyidcc from all other rodents, he adopted Gervais’s two suborders under the names Glires Simplicidentati and Glires Duplicidentati. In the arrangement of the former he pointed out a well-marked and con- stant character which separates the Myomorphi of Brandt from both the Sciuromorphi and the Hystricornorphi, namely the complete ankylosis in the former of the lower part of the tibia and fibula. Although Professor Lilljeborg does not retain these divisions in his tabular arrangements, he observes that the Myomorphi include the * Saccomyina, Waterhouse. t J. F.
