border, sometimes continued as a lateral stripe. Above purplish-ash, 

 with numerous dark spots, and often sparse ;^ellowones; side often 

 reticulated wkh yellowj tarsus and autebrachium bordered with spots 

 of the same. 



The head is short, obtuse, elevated, the muzzle slightly prominent 

 above the labial border, and sloping gentl}^ to the nearly j)lane front. 

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

 transverse contiguous fasciculi entirely between the inner nares. A 

 dermal fold over the tympanum and one across the pectoral region. 

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

 tions. The anterior are two- thirds the diameter of the membranum 

 tympani, and the posterior are a little 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 prominent and 

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

 dle of the autebrachium of the extended fore limb and the last third of 

 the tarsus of the posterior. 



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

 the orbit. 



The breadth of the cranium is contained two and two-thirds times in 

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

 the tibia enters the same two and one- third times. The o. o. prefrontalia 

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

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

 allel ; but they diverge almost transversely, and become regularly nar- 

 rower posteriorly. The form of the xiphisternum is flat-urceolatej the 

 proximal margin truncate, and the distal convexity interrupted by a 

 deep rounded emargination. 



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

 so small as to give a speckled pattern, or so large as to present a reticu- 

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

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

 surfaces are yellow, except the gular region, which is purplish-ash, with 

 or without a large subtriangular yellow mental area. The limbs all 

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

 low jiosteriorly. 



The young of this species resemble the H. squirella; but the shorter 

 heavier head and muzzle, and more obtuse canthus rostralis, the traces 

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

 brachium and tarsus distinguish it. Specimens an inch and a quarter 

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

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

 have not appeared. 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 Conte. Its range is restricted to Florida and ad-
