border, soinctiint's coiitiiiucd as a liitonil stripe. iVbovc imrplislia.sli, 

 with imiiK'roii.s daik spots, iiiul olteii sparisc jellow ones; side often 

 reticulated with yellow; tarsus and antebracbium bordered with spots 

 of the same. 



The liead is shoit, obtuse, elevated, the muzzle slightly iiromineiit 

 above the labial border, and sloi)inf>' gently to the nearly plane front. 

 Canthus lostralis obtuse; loreal region oblique. Vomerine teeth in two 

 transverse contiguous fasciculi entirely between the inner nares. A 

 dermal fold over the tyjnpanuni and olie a(!ross the pectoral region. 

 Vocal sac well developed. Hand large, as are all the terminal dilata- 

 tions. The anterior are two fhii'ds the (liameter of the membranuni 

 tynipani, and the i)osterior are a litth; smaller The tympanum is very 

 distinct, perfectly round, and with the diameter two-thirds that of the 

 eye. The eye is rather small. 



The cuneiform bone of the metatarsus is unusually jtrominent and 

 the tarsal fold distinct and infolded. The labial border marks the mid- 

 dle, of the antebrachium of tli<^ ('xtended fore limb and the last third of 

 the tarsus of the posteiior. 



The heel of the extemled hind leg marks either the middle or front of 

 the orbit. 



The breadth of the <!raninm is contained two and two thirds times in 

 the total length, and llie lenglh three and a half times. The length of 

 the til»ia enters the siime two and one third times. The o. o. prefrontalia 

 are not very widely separated anteriorly, nor are they produced beyond 

 the line of the nostrils, and their inner anterior borders are nearly par- 

 allel ; but they diverge almost ti'ansversely, and be(!ome regularly nar- 

 rower posteriorly. The form of the xii»histernum is tlaturceolate; the 

 proximal margin truncate, and the distal convexity interrupted by a 

 deep rounded emargination. 



The dark spots which cover all the upper surfaces may be absent, or 

 so small as to give a speckled ])attern, or so large as to ])resent a reticu- 

 lation of the ground. The \ cry narrow labial stripe may be continued into 

 a band or coaise yellow reticulations on the side. The groin and lower 

 surfaces are yellow, except the gular region, which is purplishash, with 

 or without a laige subtriangular yellow mental area. The lind)s all 

 dark banded, the tibia bluish on the outer side; the femur uniform yel- 

 low posteriorly. 



The young of this six'cies resemble the IF. NquireUa ; but the shorter 

 heavier head and muzzle, and more obtuse (vinthus rostralis, the traces 

 of areolation on the dorsal skiti, and the yellow borders of the ante- 

 brachium and tarsus distinguisii it. Specimens an inch and a <piarter 

 in length have not yet developed the dark cross-bands of the extremi- 

 ties; in many of an inch, dorsal sjjots are invisible, and the areolations 

 have not apiieared. As is always the case with young frogs, the ex- 

 tremities are relatively longer. 



This beautiful species readily changes its color from green to brown- 

 ish, according to Le <,'ont(\ Its range is restricted to Florida and ad-
