II. ANNALES MUSEI NATIONALIS HUNGARICI. 1904. INVESTIGATIONS ON PARAGUAYAN BAT R AC 1 HI ANS. By Prof. L. v. MBHELT. (Plate XIII.) Our countryman Mr. J. DANIEL ANISITS, Professor of the National College in Asuncion, sent to the Hungarian National Museum a few months ago. among much other material, examples of 21 species of Batrachia. Though the most species, collected in the year 1903 near Asuncion and Villa Sana, seems to he the same with which we are acquainted through the previous explorations OÎDAUDIN, SPIX, GIRARD, STEINDACHNER. COPE, BOETTGER and BOCLENGER, I was able to make some remarkable observations in anatomical, systematical and biological sense. With regard to my systematical results I will point out that though Paraguay in herpetological respect is much allied to Argentinia and the Matto Grosso, it seems that the species which inhabit this country are not quite the same, but are replaced in some cases by vicarious forms. Whether these forms may be regarded to as subspecies or merely as varieties, could only be judged by real comparison with the animals of the neighbouring countries, what to do 1 had not the opportunity. For this reason I have restricted myself to describe conscientiously the material before me. I hope that my views with respect to the adaptation to the mode of life, the means of defence, especially the de fence-markings of some frogs, which belong with certainty to the appearence of mimicry, will be kindly accepted by my scientific collègues. Finally 1 take the opportunity to express my hearty thanks to Prof. B. HERTWIG and Mr. LORENZ MÜLLER in München, Dr. FR. STEINDACHNER and Dr. FR. SIEBENROCK in Vienna. Dr. Count MARIO G. PERACCA in Torino, Mr. G. A. BOULENGER in London and Prof. G. TORNIER in Berlin, who were kind enough to send me some types or other material for investigations. Farn. ENGYSTOMATIDAE. Dermatonotus n. g. Pupil erect. Tongue large, elliptic, entire, free in its posterior half. Vomerine teeth none. A short dermal ridge between the small auditory tubes. Tympanum hidden. Fingers and toes free, the tips not dilated.
