two, often elongate, curved series behind the posterior nares. Skin of abdo- 

 men smooth. H. lineatus, lentus, cuneatus, luteolus, planiros- 

 tris, dimidiatus. This group connects with Hylodes proper through H. 

 cuneatus. 4. Euhyas Fitz. Toes free. Vomerine teeth in two elongate, 

 angularly curved series, which are medially directed posteriorly and in contact, 

 forming a zigzag line behind the anterior nares. Abdomen smooth or granular. 

 H. ricordii, oxyrhynchus. The dentition of this group is nearly ap- 

 proached by that of H. (Lithodytes) lentu s. 5. Batrachyla Bell. Toes free. 

 Vomerine teeth in two straight oblique groups between the posterior nares. 

 Abdomen smooth: a. Tympanum round. Batrachyla. H. leptopus, lon- 

 gipes. b. Tympanum vertically elliptic. Halophila Gird. H. h e r o s, 

 chryseus,* dorsalis, vitianus, corrugatus. 



Hylodes 1 a t i c ep s is perhaps the type of a distinct genus. Ranacapito 

 Leconte bears some resemblance to it. 



Phyllobates limbatus. 



Size very small; form ranine. Head not wider than the body. Muzzle 

 rather acute. Skin smooth below, slightly granular upon the lateral, gluteal 

 and occipital regions. Tympanic disc two-thirds the size of the orbit. 

 Nostril lateral, its position one-third the distance from the muzzle to the orbit. 

 Internal nares much smaller than 03tia pharyngea. Tongue elongate, sub- 

 cylindrical, entire. Palms and soles granular; outer metatarsal tubercle very 

 small. A delicate dermal fold on the median line of the back. Heel scarcely 

 reaching the orbit. Length of head and body 5 1. Hinder extremity 8 1. 



Above, chestnut. A white line extends from the end of the muzzle to the 

 knee joint; beneath this a broad, black band extends to the same position. 

 Upper surfaces of posterior extremities and anal region blackish brown. Under 

 surfaces and anterior extremities yellowish, the hinder limbs and sides of 

 abdomen spotted with brown. A dark line on humerus. Upper lip yellow. 



Habitat. Eastern Cuba. Mus. Smithsonian, (No. 5206.) Mr. Chas. Wright's 

 Coll. Acad. Philada. 



This is, perhaps, the smallest frog known, and is a very prettily marked one. 

 Suspicions of immaturity have been removed by careful examination of the 

 six specimens at our disposal. 



Hyla andersonii Baird, Proc. Acad. Nat. Sci. Phila., 1854, p. 61. 



In proportions and general appearance similar to the Hyla arborea oi 

 Europe. The skin of the upper surface of the body and extremities is smooth, 

 minutely corrugated ; that of the throat, belly, and under surfaces of the femora, 

 is areolated. A cutaneous fold across the breast, and one across the throat. 

 Tympanum about one-third the size of the eye. Tongue broad, slightly 

 emarginate. Vomerine teeth in two oblique series between the internal nares. 

 each directed inward and backward. 



Coloration in life. The whole upper.surface a rather deep pea green, paler 

 upon the sides and the margin of the upper lip. A narrow band of purplish 

 brown commences at the external nares, passes through the eye and including 

 the tympanum, loses its inferior border a little beyond the insertion of the 

 humerus. The color becomes paler upon the sides, where it is of an ashy 

 mulberry tint, and extends as far as the origin of the femur. Anterior to this 

 point it is margined below by large irregular spots of a beautiful saffron, which 

 are continued upon the anterior and posterior surfaces of the femur, and the 

 whole inferior surface of the tibia, upon a ground of a paler shade of the same 

 color. The supero-anterior surface of the tarsus, the three inner toes and the 

 webs of the external, also a small area behind the humerus, the posterior 

 surface of the latter, the infero-anterior face of the fore-arm and the inner
