[Eeceived October 8, 1895.] The structure, arrangement, and relationships of the buccal glands and teeth of poisonous Snakes, although an extremely interesting subject, is one upon which very little work has been recently done. Conspicuous among recent papers is one by Niemann2, dealing with the structure and relationships of the glands of the upper lip in a few genera3. M y own observations differ considerably from his in many points. H e describes and figures the glands as consisting of long convoluted tubules, whereas 1 From the Biological Laboratory of the Eoyal College of Science. 2 F.
