Peale 18 states that in his examples " the females have two 

 pectoral and four abdominal teats," whereas in mine the pectorals 

 are four. This may be reconciled by supposing that Peale over- 

 looked a pair of mammae, an error, as I have in a former article 

 indicated, easily committed. 



Three examples of the Funafuti native rat were included in 

 the collection : two of these I had not the opportunity of 

 examining. The third had the skull a little but not very 

 seriously damaged, and fragments of a fourth specimen enabled 

 me to add the few figures in the second column of skull 

 dimensions. 



The stomach of the rat examined contained a white vegetable 

 substance, possibly cocoanut or pandanus. 



On the Funafuti Atoll this rat is known to the inhabitants by 

 the name of "Tikimoa."
