LARS GABBIEL ANDERSSON, BATRACHIANS. 



there are regular black spöts disposed in pairs separated by a very narrow white verte- 

 bral line; in a specimen as large as 22 mm. in length we still find some traces of 

 the juvenile colour pattern; as mentioned above, the narrow vertebral line is visible 

 to some extent also in the adult specimens, especially in the females. 



By the absence of tympanum and by the very long and narrow parotoid glands 

 this species resembles Bufo taitanus Peters, and although the differences between 

 these specimens and Peters' figure were rather remarkable I beJieved them to be 

 identical with that species, as the old figure might be less correct. By the great 

 kindness of Dr. Fr. Nieden I have, however, received a specimen of Bufo taitanus 

 which according to him is completely like Peters' type-specimen, kept in the museum 

 in Berlin. The specimen received, figured on my plate, figure 5, shows that the 

 present specimens cannot be identical with Bufo taitanus. Especially the hand, and 

 the foot are very much different. The drawings 6 and 7 which are prepared from 

 specimens of exactly the same size, and enlarged in the same scale show that the 

 fingers and toes are remarkably longer in my specimens, and the foot is nearly twice 

 as large in this species as in Bufo taitanus. Besides the metatarsal and subarticular 

 tubercles are larger and exceedingly more prominent in B. taitanus; the soles of the 

 hand and foot as well as the upper surfaces of the whole animal of the species just 

 mentioned are spiny tubercular, while these parts in my specimens are smooth or nearly 

 smooth. The limbs are also shorter in B. taitanus. The colour of the latter reminds 

 of that of the young specimens of the new species; in none of the adult specimens 

 we find the markings which have been referred to above as being like those of Bufo 

 regularis. 



The following measurements show the different development of the limbs in 

 the two species.

From Bufo anotis Blgr., another small J5«/o-species without tympanum, this 

 species is most easily distinguished by its quite different appearance of the parotoid 

 glands.
