794 THE AMERICAN .NATURALIST. [Vor. XXXIV. 
A case which resembles Phyllobates and the like, superficially 
at least, has been discovered by Brauer (98) in the Seychelles. 
Arthroleptis seychellensis inhabits a forest about 500 feet above 
the sea, where the streams are swift and there is no still 
water. The frogs are found in decayed trunks and among 
damp leaves on the ground, and on one occasion, late in 
August, a number of eggs were found under leaves from which 
the adult had been frightened away. The eggs were not in- 
cluded in a common gelatinous covering; they hatched in a 
glass, and the tadpoles immediately stuck to the glass by their 
abdomens.  Tadpoles of about the same stage of development 
were also found adhering to the back and sides of an adult. 
The tadpoles had prominent eyes, mouth well under the ante- 
rior end of the head, short hind legs, fore legs concealed 
beneath an operculum, rudder tails more than twice as long as 
the body, and a large amount of yolk bulging out on either 
side of the body. No opening was found to the operculum, 
and no internal gills, nor were the rudiments of lungs discov- 
ered. The outer layer of epithelial cells on the abdomen was 
columnar, making the epithelium appreciably thicker there 
than elsewhere; gland cells were wanting on the abdomen 
only, though a slimy secretion covered the surface. An adult 
carrying older tadpoles was found at another time. Gland 
cells were present on the abdomens of these tadpoles; the 
anterior legs had come through the skin, the toes were found 
. on all the feet, the length of the tail was not reduced in pro- 
portion to the body, and much yolk was still present. Rudi- 
ments of lungs were found, and the entodermic epithelium had 
differentiated from the yolk. ; 
Brauer concludes that the eggs are covered with leaves by 
the parent (probably the male), that the young, when hatched, 
place themselves, with the assistance of their tails, on the 
parent's back, where they adhere partly by suction, partly by 
aid of the roughness of the parent's skin, and partly by a secre 
tion, largely from the adult. Finally, the tadpoles are not 
attached to the parent for transportation to water, but undergo 
a large part of their development on its back.
