. The tailless batrachians of Europe. Frogs; Amphibians. 62 INTRODUCTION. in BaiM, or slit-like, and situated at the side of the tongue, as in most other genera. Pelodytes and Hijla have two openings, whilst Biofo has commonly but one, either on the right side or on the left. In Bomhinator 'iij)ie)i,s internal vocal sacs are well developed, but are formed by the skin of the floor of the mouth, which is loose and plicate, and projects through a slit dividing the submaxillary muscle into an anterior and a posterior portion. Discoglossus has rudimentary vocal sacs of the same type, but they are confined to the sides of the throat, near the mandible. Bomhinator facliyjms, Ah/tes, Pelohates, Bufu vulgaris, and Bana graica, lutasfli, iberica, and agilis lack the vocal sacs. The mode of inflation of the vocal sac is best observed in Tlyla arborea, the bladder-like appendage when blown being of enormous size, nearly as large as the body, which, when the animal croaks, is much Fig. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Boulenger, George Albert, 1858-1937.
