MEXICAN AMPHIBIANS—TAYLOR AND SMITH 601 
“While no doubt the local population of Agalychnis was depleted by 
collecting all the adults that could be found, at the same time prob- 
ably many times that number of eggs was saved, for the snakes would 
certainly have eaten many hundreds of eggs before they fell into the 
water.” 
Genus CENTROLENELLA Noble, 1920 
CENTROLENELLA FLEISCHMANN I (Beoettger) 
Hylella fleischmannt BortrenrR, Ber. Senck. Nat. Ges., 1893, p. 251 (San José 
Costa Rica). 
Centrolenella fleishmanni (sic) TayLor, Univ. Kansas Sci. Bull., vol. 28, pt. 1, No. 
5, May 15, 1942c, p. 74. 
A single specimen, U.S.N.M. No. 115499, is referred to this species. 
It was taken at night during the dry season (April 19, 1940) at Salto 
de Agua, Chiapas, sitting on the leaves of a plant near the edge of a 
small rocky stream. In life it was pale green above, translucent 
below. The bones, visible through the flesh, were white. 
Genus ANOTHECA Smith, 1939 
ANOTHECA CORONATA (Stejneger) 
Fieure 60, B, C 
Gastrotheca coronata STEINEGER, Proc. U.S. Nat. Mus., vol. 41, Aug. 14, 1911, pp. 
287-288 (Palomo, Valle de Orosi, Cartago, Costa Rica). 
Anotheca coronata SmitH, Proc. Biol. Soc. Washington, vol. 52, Dec. 15, 1939, pp. 
190-191, pl. 1, figs. 1, 2, 8, pl. 2, fig. 6. 
In all, 138 specimens were secured, of which U.S.N.M. Nos. 116398- 
116412 are cataloged. All are from Cuautlapan, Veracruz, collected 
January 1-16, 1939, December 20, 1939, and August 7-14, 1940. This 
series has been discussed earlier (Smith, loc. cit.). 
A row of high spines crosses the back edge of the skull, above the 
tympanum, and decreases somewhat in size on the borders of the orbit, 
while those along the canthus are very short. Each is surrounded by a 
fleshy glandular apophysis, which appears to be some specialized type 
of gland, perhaps for poison. A substance is exuded when the live 
specimens are placed in alcohol and forms a thick yellow cream mat 
about the bases of the apophyses. The spines are fixed projections 
from certain bones of the head, curved forward or inward, and are 
fanglike in character.. Ordinarily, when the glands surrounding the 
spines are full, the spines are almost completely hidden. When they 
are discharged the sharp top part of the spines is exposed. The spines 
vary greatly in length, the largest being something over 4 mm. in 
length. These objects are developed in both sexes, but their size is 
distinctly smaller in the females (see fig. 60, B, C). 
Specimens were obtained from under the petioles of the banana 
leaves. These outer sheaths loosen and form cavities which may be
