This splendid series, albeit the specimens are rather dried, exhibits 

 an almost incredible amount of variation and jQt no topographical 

 significance can be detected sufficient to warrant one in attempting 

 to define geographical races; in every case the extreme types appear 

 to form part of a series in which the more typical form also appears. 



Under the name of Bujo regularis gutteralis, Power ^° has recently 

 described a race from Lobatsi on the border of Bechuanaland, South 

 Africa. I agree with him in recognizing it on account of the call 

 notes of the males, which he found to differ very markedly from that 

 of the common regularis which is widespread in South Africa. It is 

 also slightly smaller in size, 30 examples of gutteralis averaging 11 mm. 

 less than in 30 specimens of the typical form. In the webbing of 

 the toes East African toads agree with typical regularis, for the 

 webbing does appear to be more or less prolonged as a border to
