ON THE FAMILIES OF THE RANIFORM ANURA. 201 



Calamita cyanea Daudin. Australia, New Guinea, 

 dolichopsis Cope, sp. nov. Aniboina. 

 Centrotelma geographicum Spii. Brazil, Sur. 

 cryptomelan Cope, sp. nov. Brazil. 

 Hyla. species cognita, 76. 



Hypsiboas i n d r i s Cope, sp. nov. Surinam, 

 doumercii D. B. Surinam, 

 punctatus Daud. Brazil, Surinam, 

 crepitans "Wied. Brazil, 

 boans Daud. Brazil, Surinam, 

 albipunctatus Spix. Brazil. 



The names adopted for the above genera are, with one exception, those emploj^ed 

 by certain authors for species now embraced in the latter. As they were employed 

 without discrimination of the natural genera, their re-employment is rather with the 

 view of avoiding multiplication of names, than as a measure of justice. 



It may be added that a batrachian, apparently referable to the Hylidfe, has re- 

 cently been described by Dr. Steindachner (Reise du Novara 65) under the name 

 Ololygon abbreviatus, supposing it to be the Htjla ahhreviaia Spix. The latter is, 

 however, very different, being a Cystignathid of the genus Enhydrobius Wagl. Olo- 

 lygon appears to be very near Thoropa Cope, if not the same. Pohlia, of the same 

 author and work, is probably Ranula Peters, as defined by me, Proc. Acad. 1866, 129. 



Among many new and interesting forms of Anura, mostly very well figured, the 

 same author describes a new species of Neobatrachus Peters, giving it, however, 

 another generic name, ^. e., the Opisthodon fravsnfeldti ; his Helloo-ana (nomen hy- 

 bridum !) grayi is the Platyplectrum d u m e r i 1 i i Peters, too briefly described by the 

 latter author. Another example of the vox hybrida is the name Cyclorana, of an 

 interesting novelty, which with the practice of forming personal generic names, for 

 the first time introduced to any extent into the history of the cold-blooded verte- 

 brates, is to be condemned. 



Ceinia stolata Cope, sp. nov. 



The writer is acquainted with nine species of this genus, of which C. stolata and 

 C. georgiana attain the largest size. Several of the species lack vomerine teeth 

 and were on this account separated by Girard under the name Ranidella ; the same 

 type has since been named, by Sutken, Plerophrynus, and later, Camariolius, by 

 Peters. 



Prefrontals well separated; sides and all under surfaces areolate ; back without 

 warts, but with a strong dermal fold from each supercilium approaching the other at 

 scapulae and following length of ilium ; two other folds on each side, two converging 

 on parietal regions and one on middle line of muzzle; two metatarsal tubercles; from 

 end muzzle to vent between folds black; a broad dorsolateral pink brown band, and 

 darker lateral ; groin and femora carmine ; below white. 



In this species the posterior dorsal and sacral region is strikingly concave, owing to 

 the elevation of the diapophyses. Tympanum not invisible, one-third orbit ; nostrils 

 -as near lip as orbit. End of fore-arm measures between orbit and nostril; heel to
