are usually deeper brown than older specimens, and the sides of 
the head and body are frequently black. Many specimens have 
the belly and throat strongly mottled with dusky. 
Remarks.—Only two specimens were obtained at Zamboanga 
along Tumugao River. None were found at Isabela or Port 
Holland on Basilan, but this species was not uncommon at 
Abung-abung in the southern part of the island. Females were 
usually found in the forest at a considerable distance from water. 
Most of the males were collected in a small forest stream at a 
point where a tree top had fallen into the water. More than 
fifty males and but one or two females were captured there. 
The species appears to be related to Rana erythrea of the 
Philippines. It differs in markings, in the greater amount 
of granulation on the back, in having much larger eyes, in the 
narrower interorbital distance, and in having transverse bars 
instead of longitudinal lines on the femur and tibia; the outer 
metatarsal tubercle is very strong. The last character is want- 
ing in the continental and Malayan Rana erythrza, but a small 
tubercle is evident in specimens supposed to be of this species 
from Negros and Sibuyan. The name for the species is taken 
from the tribe of people inhabiting the interior of Basilan. 
Rana sanguinea Boettger. 
Rana sanguinea BoETTGER, Zool. Anz. 16 \(1893) 364; TAyLor, Amphi- 
bians and Turtles of the Philippine Islands (1921) 60. 
Specimens of this species were obtained in Busuanga, by 
Gregorio Lopez, of the Bureau of Science. The specimens are 
not full grown. The body is reddish brown above, and dark 
on the sides. The characteristic black mark covering the 
tympanum is well defined. The throat is dusky with an elongate 
streak under the point of insertion of the arm, and there are 
two spots on the back part of the throat.

Specimens of Rana erythrea were recently collected on Sibu- 
yan Island. I have also specimens collected in Negros. British 
Museum specimens from the Philippines bear only the label 
“Philippines.” Fischer,? records a specimen from southern Min- 
danao collected by Doctor Schadenberg in 1881. No other col-
