The color of the upper surfaces is a reddish brown; below, leather 
brown. The back is thickly spotted with large darker or blackish spots, 
the largest of which reaches to between the eyes. The sides are marbled 
with lighter and darker, but the femora are unicolor. Limbs obscurely 
cross-banded ; below uniform, upper lip with a few pale spots. 
Numerous specimens of this species were found by Francis Sumichrast 
at Potrero near Cordova, Vera Cruz, under decayed trunks of trees. It is 
of more lanciform proportions than the Central American species, P. hyla- 
formis and P. ringens. 
CYSTIGNATHUS LABIALIS Cope. 
Vomerine teeth in transverse series behind the posterior border of the 
internal nares ; toes without dermal border ; no abdomdinal discoidal fold ; 
posterior limbs short ; end of metatarsus just reaching muzzle, muzzle short; 
not projecting ; teeth much behind choane; one dermal fold on each 
side ; skin rough ; below white. 
This small species belongs to that division of the genus, in which the 
toes do not possess dermal margin, and there is no discoidal fold of the ab- 
dominal integument. Among these it is distinguished by the shortness of 
the series of vomerine teeth and the paucity of dermal plice. The muzzle 
is acuminate and rather narrow, but not projecting as in C. gracilis; the 
canthus is not distinct. The tongue is oval and a little notched behind ; 
- the choane are small. The diameter of the tympanic disc is one-half that 
of the orbit. The heel only reaches the orbit. The toes are not very long ; 
there are two small tarsal tubercles, and a narrow tarsal fold. 
Color chocolate brown, the limbs darker cross-barred. A brilliant white 
band extends from the anterior part of the upper lip, and describing a curve 
upwards, bounds the orbit below and descends to the canthus oris, from 
which point it continues in a straight line to the humerus, and ceases. In- 
ferior surfaces, pure white. Length of head and body, .020 ; of head, .007 ; 
of bind limb, .028 ; of hind foot, .013. 
The precise habitat of this species is at present uncertain. It is probably 
a part of Sumichrast’s Mexican collection.

This Caecilian resembles so much the S. mexicanus that I referred spe- 
cimens of it to that species in my Batrachia and Reptilia of Costa Rica. It
