From Museum Drottningholmense there are four speci- 

 mens, marked B.a)ia pipa. They are all true Fipa americana 

 Laur. or Pipa pipa, as this species ought to be ealled, if we 

 want to maintain the Linnean name. Three are females with 

 young ones in the pouches in the back.

Quensel mentions iive specimens in different stages of 

 development to be found in the R. Museum, all of which 

 should be from Museum Drottningholmense. From the old 

 collections we find at present the same number of this frog, 

 though two specimens onjy — two tadpoles, the one with 

 very small hind limbs, the other with fairly large such — are 

 provided with the Drottningholm labels. Of the others, also 

 propably from Mus. Drottnh., one has still the whole tail left 

 but all the limbs developed (on the label from Quensel is 

 written: »Råna paradoxa pedihus omnihus cxpUcatis»), on an- 

 other has the tail almost disappeared (on the label from 

 Quensel is written: Bana paradoxa canda dimiduata), and 

 the third is a completely developed frog (on QuenseFs label: 

 •!>Rana paradoxa perfecta»).
