GiJNTHEE, F.R.S., Keeper of the Department of Zoology, British Museum. T"WO small collections made in tlie island of Dominica by Mr. Eamfige, a gentleman engaged by the West-Indies Ex-ploration Committee, contain a very interesting series of the reptiles and frogs of that island. Mr. Ramage has been working in the island for a short period only, so that we may expect further additions to this present list, which consists of five species of lizards, three of snakes, and two of frogs. Of particular interest would be observations on the mode of propagation of the Hylodes.
