100 THE HERPETOLOGY OF CUBA. 
so many of the larger species of Bufo the white discharge from the parotoid 
glands is copious and powerful, and experience has taught both men and dogs 
of its highly venomous nature. 
The young are found in bands along the Guarda Rayas of the Guantanamo 
cane fields in the spring, especially if it has been a rainy one. They develop 
in the drainage ditches of the cane-fields and are beautifully marked with 
splashes of rich dark green on the brown. 
There is a belief among the country folk, in many parts of Cuba, that the 
big toad cannot live in the woods where the Cuban Solitaire (Myadestes eliza- 
beth (Lembeye)) is found. For upon hearing the heavenly flute-like strains of 
these glorious peerless songsters, the toads try to imitate them with their gut- 
tural croakings so strenuously that their attempts end fatally. As a matter of 
fact, however, the Bufo is not found in the deep woods about Guantanamo 
where the Myadestes abounds, although it occurs plentifully about the Sierra 
de Paso Real, Sierra de Guane, and in the valley of Luis Lazo where Solitaires 
are very often to be heard; higher up to be sure than the toads, but well 
within hearing.

Sapo de concha; Guasdbalo. 
Diagnosis:— A rather small toad living in burrows, in large colonies, hay- 
ing the whole head extremely hard and bony, the cephalic crests very prominent 
and the lip margin hard and modified for digging. 
Description:— Adult M. C. Z. 2,833. Cuba: Pinar del Rio; Herradura, 
March, 1910. Thomas Barbour. 
Top of head bony, with enormous crests, enclosing a deep hollow between 
the orbits, the canthal crests meet anterior to the nostrils and form a V, then 
merge with the enormous supraorbital crests; the anteorbital crest is likewise 
prominent, the supratympanic crest is far less prominent and ends in a small 
knob; two crests on the occiput converge but do not meet, they are continuous 
with supraorbitals and are composed of high, flat tubercles partly confluent; 
snout rather depressed,. the labial margin produced into a hard flange extending 
around the snout; tympanum elliptical, erect, its greatest diameter scarcely 
one half that of the eye; parotoid gland small, long, simply the anterior elabora-
