The difference be- o tween these characters is made clear in the figures. The Gane specimen was taken in the deep woods without any fresh-water near by. In this in- dividual the vomerine teeth are rather more separated, and are placed in a slightly more anterior position than is the case with any one of the Ternatian series. The interorbital space is sUghtly wider in the example from Halmahera than in the others. It is also much more brilliantly colored, the legs being heavily barred above, and very brilliant yellow below. This coloration may have relation to the nuptial season, or may be due to life in the woods. The lot from Ternate were all taken from a well, the water in which stood almost level with the surface, and from which the frogs could have easily escaped. They seemed to be hv- ing a strictly aquatic life. They were taken a month later than the Gane frog, in late February, instead of January. It is not safe to draw any conclusions from so unevenly distributed material; but this series points strongly to a frog upon Ternate which is not certainly identical with those on Halmahera, and is certainly not identical with Rana varians of Palawan. Nevertheless, the origin of these frogs is all the same, and the close relationship serves to emphasize the existence of a connection from the Phillippines through Celebes to the Halmahera group. It will be very instructive to learn whether a frog of this type occurs on the Sula Islands, Obi, or Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrat
