Length of head and body 19'" : of anterior extremities 10'" ; of posterior 25'". 



Extremities, lower surfaces, loreal and labial regions grayish-brown ; upper 

 surface of head and body pale ochreous, abruptly separated from the other 

 color all round. 



Habitat. Paraguay. From Capt. Page's Expedition. Mus. Smithsonian, 

 (No. 6225 ;) Academy Natural Sciences. 



Hyla b a u d i n i i Dum. Bibr., Erp. Gen., viii. 564, 1841. 



The names Hyla vanvlietii, published in these " Proceedings" for 1854, p. 61, 

 and H. muricolor, 1862, 359, apply to forms of this species. It is fmnd in 

 Texas, Eastern Mexico and Honduras. Mus. Academy, Phila.; Smithsonian. 



Hyla (Hypsiboas) oxyrhina Rhdt. et Lutk., Videnskab. Meddelelser, etc. 

 Kjobenhavn, 1862, p. 189. 

 This species is identical with that described in these "Proceedings," 1862, 

 p. 353, as Hypsiboas raniceps. The name of the distinguished Danish zoolo- 

 gi=t must be retained, as the memoir in which it appeared was issued some 

 months prior to our own. The former has just come into our hands. 



Hylodes Fitz. 



Hylodes planirostris Cope, Pr. A. N. S. Philada., 1862, p. 153. 



This species, hitherto known as a native of the Bahama Islands, has been 

 sent to the Mus. Smithsonian (No. 6310) from Southern Florida by Dr. Cooper. 

 It is the only species of the genus found in the United States, though Holbrook 

 and Agassiz have described frogs under this name from our country. These 

 belong to the genera Acris, Hyla and Pseudacris. Other reptiles common to 

 the Bahamas and Florida are Anolis principalis and Sphaerodactylus 

 n o t a t u s. 



The following species of Hylodes form a little group which I have called 

 Craugastor, 'Proc. A. N. S., 1862, p. 153. They can be distinguished as 

 follows : 

 H. p u 1 c h r i g u 1 u s, 1. c, 1862, 357. 



Tympanum one-fourth extent of orbit ; the latter equal distance from its 

 anterior border to end of muzzle. Carpus reaching anterior border of orbit. 

 Muzzle truncate. Tongue emarginate. Loreal region concave. End of tibia 

 reaching the end of the muzzle. 

 H. g r is e u s. 



Hylayrisea, Hallow., Pr. A. N. S. Phila., I860, p. 485. 



Tympanum obliquely elliptic, one-third the extent of the orbit; diameter of 

 the latter less than the length of the rather elongate and rounded muzzle. 

 Carpus and end of tibia reaching the end of the muzzle. Loreal region con- 

 cave ; canthus rostralis strong. Tongue emarginate; external metatarsal 

 tubercle not developed. 

 H. h a 1 1 o w e 1 1 i Cope, 1. c, 1862, 153. 



Tympanum horizontally elliptic, equal one-third extent of orbit; latter equal 

 in diameter to length of muzzle, which is much rounded; loreal region nearly 

 plane ; canthus rostralis weak. Carpus reaches end of muzzle, the tarsus only 

 the orbit. Two well developed metatarsal tubercles. Tongue entire ; mandi- 

 bulum rounded. 



Herr Schmidt has not given the minuter peculiarities of his H. (Craug.) fit z- 

 i n g e r i i so as to enable us to distinguish it from the above. It is most like 

 the pulchrigulus. 



Phyllobates Bibr. 

 Phyllobates latinasus Cope, sp. nov. 



Head elongate ; front plane transversely, gently arched longitudinally, a little 

 wider than from orbit to end of muzzle. The latter is prominent, broad and 

 ooncavely truncate ; external nares lateral. Loreal regions plane. Internal
