MAMMALS FROM MOUNT COFFEE, LIBERIA 649 



error in the original description of P. stanipjiii in which the length of 

 forearm is recorded as 32 mm. instead of 27 mm., he continues (in 

 letter under date of April 22, 1900): "your Liberian bat is still 

 smaller [than P. stampjlif\^ but its tail is longer. I think it is a new- 

 species, particularly as it is much browner-red colored than stajnpjlii. 

 As far as I can see the dentition is the same, though all the teeth ap- 

 pear to be smaller." The more important measurements of the type 

 of Pipistrcllus stainpjiii are : total length 62 ; tail vertebra) 24 ; fore- 

 arm 27.
