tion to the reft of the Frog-genus in being viviparous, 
and is likcwife an exception to the general way of 
production in all other larger animals. 
This moll extraordinary creature is a native of Su¬ 
rinam. Its colour, (at lead in fuch Ipecimens as are 
brought over to Europe) varies confiderably in dif¬ 
ferent fubjeCts ; but ir is generally brown, more oy 
lefs deep, and in fomc, even approaches to blacknefs. 
It is a fpecies of moft ltriking 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 proceflcs. 
I fliould not omit to obferve, that according to the 
celebrated anatomift Camper, the Pipa is furniflied 
with an internal uterus, or ovarium, and excludes its 
ova in the manner of other animals of this genus; 
and, from the obfcrvations of Fermin, (who declares 
he was an eye witnefs of the ftrange procefs,) 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 x'eceived into the cellules, which clofe 
over them, and in which they gradually arrive at 
their complete form, and are then again excluded. 
I his lingular animal is calculated by nature for 
bearing young but once j and, compared with others 
of its genus, it cannot be regarded as very prolific ; 
the number which the female Pipa, obferved by Fer¬ 
min produced, was feventy-five, which w ? ere all ex¬ 
cluded in the fpace of five days.
