614 The American Naturalist. (July, 
Superior postocular three times as large as inferior. Vertebral scuta 
wider than long. While the dorsal spots are acute angled below gener- 
ally, they are not so on the tail and anterior region ; on the latter many 
of them are separated by a much smaller vertebral spot. Top of head 
brown, brown spotted; lips and throat unspotted; other inferior 
regions black speckled. Total length 622 mm.; tail 189 mm. _ Pebas, 
Ecuador, J. Hauxwell; E. Equador, J. Orton. 
The characters of this species are well marked, as compared with 
those of the H. cenchoa. Of the latter I have four from Peru (Orton) 
and one from Ecuador (Hauxwell.) 
Himantodes semifasciatus sp. nov. The width of the vertebral series 
of scales varies in the numerous specimens I have assigned to the H. 
semifasciatus ; in some the width is nearly equal to the length, while in 
others it is considerably less. The apices of the vertebral scales are, 
however, always truncate, and never acuminate like the other scales, as 
is seen in the H. gemmistratus. There are usually two scales in the 
first temporal row in this species, while there is invariably only one in 
the H. gemmistratus, but in three of the nine Costa Rican specimens 
there is but one scale. The largest specimens belong to the H. semi- 
fasciatus. One of these (No. 101) measures; total length 1125 mm.; 
tail 380 mm. 
Ten specimens from Costa Rica; Paso Azul, Santa Clara, Carrillo, 
Alajuela, Monte Aguacate, and San José; from the Museo Nacional, 
through Geo. K. Cherrie. Two specimens in Mus. Academy, Philada. 
from Nicaragua. 
Himantodes anisolepis sp. nov. Besides the characters already men- 
tioned, the following may be noted. The small inferior preocular is 
cut from the fourth superior labial; the labials number eight above 
and ten below. The lower post-ocular is one-third the size of the supe- 
rior. Temporals 2-2-3. The postgenials are entirely separated by 
scales. Thirty-nine brown spots from the head to the vent, which ex- 
tend nearly to the gastrosteges, with truncate or rounded inferior 
border, on avery pale ground. Belly unspotted. Total length 420 mm. 
of tail, 127 mm. Monte Aguacate, Costa Rica, G. Witting. 
This slender species resembles in coloration the H. tenuissimus and H. 
leucomelas. It differs sufficiently in scale characters from both.—E. 
D. Cope. 
Zoological News.—M. de Guerne recently reported to the 
Société Acclimatation de France the capture in the open sea of a female 
eel bearing mature eggs. (Rev. Sci. March, 1894.)
