XVI. — On a new Species of the Genus Pipa from Northern 

 Brazil. By Lorenz Muller, Curator, Division of 

 Herpetology, Munich Museum. 



Among a number of Reptiles and Amphibians recently sub- 

 mitted to my inspection by Dr. Emilia Snethlage, the 

 distinguished zoologist of the Para Museum, there are 

 several examples of a " Surinam toad,^"* which evidently 

 belong to a well-characterised new species of that peculiar 

 Neotropical genus. I have before me one male and two 

 females, the latter with empty egg-capsules on the back, 

 consequently fully adult. I propose to name this interesting 

 form in honour of Dr. E. Snethlage. 



Pipa snethlagece, sp. n. 



Type in the Zoological Museum, jNIunich, No. 1/1914 ; 

 ? , Utinga, near Para (Belem), State of Para, N.E. Brazil.

Ditiers from Pipa pipa (Linn.), hitherto the only known 

 representative of the genus, by its smaller, less decidedly 

 triangular head; more rounded snout, hardly projecting 

 beyond the mandibular symphysis ; stouter, less depressed, 

 on its posterior portion much enlarged, rump ; shorter as 

 well as weaker limbs with the upper arm and the upper 

 thigh mostly concealed in the skin ; by the rudimentary 

 development of the tentacles on the snout and of the dermal 

 flap at the angle of the mouth. Moreover, the four rows 

 of small glands on the back, so conspicuous a feature in 

 Pipa pipa, are entirely lacking, while the general structure 

 of the skin is altogether different, and the inner metatarsal 

 tubercle is much less pronounced in the new species. 

 Besides, Pipa snethlayece is very much smaller, the adults 

 being hardly half as big as specimens of P. pipa in corre- 

 sponding age.
