tion to the reft of the Frog-genus in being viviparous, 

 and is likewife an exception to the general way of 

 production in all other larger animals. 



This molt extraordinary creature is a native of Su- 

 rinam. Its colour, (at leaft in fuch fpecimens as are 

 brought over to Europe) varies confiderably in dif- 

 ferent fubjeifts ; but ir is generally brown, more of 

 lefs deep, and in fome, even approaches to blacknefs. 

 It is a fpecies of molt Itriking deformity ; the head is 

 of a fort of pointed fhape, the fnout fomewhat like 

 that of a hog; and the toes of the fore-feet are at 

 their extremities divided into four fmall proceffes. 



I fhould not omit to obferve, that according to the 

 celebrated anatomift Camper, the Pipa is furnifhed 

 with an internal uterus, or ovarium, and excludes its 

 ova in the manner of other animals of this genus ; 

 and, from the obfervations of Fermin, (who declares 

 he was an eye witnefs of the ftrange procefsj it ap- 

 pears, that the male, after the exclufion of the ova, 

 collects the whole heap, with his paws, and depofits 

 it on the back of the female, where, (after impregna- 

 tion) they are received into the cellules, which clofe 

 over them, and in which they gradually arrive at 

 their complete form, and are then again excluded. 



This lingular animal is calculated by nature for 

 bearing young but once ; and, compared with others 

 oi its genus, it cannot be regarded as very prolific ; 

 the number which the female Pipa, obferved by Fer- 

 min produced, was feventy-five, which were all ex- 

 eluded in the (pace of five days.
