Remarks. — This species is not liable to be confused with the other 

 species of the genus, but its three subspecies are all, with the possible 

 exception of C. m. grisea, quite closely related. From madeayii grisea 

 the true madeayii may be separated by its smaller size and the shape 

 of the superior margin of the nostrils; from m. juliginosa the larger 

 size and heavier build will distinguish it; from vi. inflata the shape of 

 the rostral portion of the skull, as well as the general slenderer 

 character of the palate and zygomata, will serve to differentiate it. 



The most striking variation exhibited by this species is the occur- 

 rence of two forms, one considerably smaller than the other. This 

 fact was first noticed by Miller (l. c), and, as he states, it appears to 

 be independent of age or sex. The series studied, while a picked lot 

 from the series he examined, do not give the extreme dimensions he 

 cites, but the two forms can very readily be distinguished. Another 

 very striking variation is in the shape of the skull, and is apparently 

 sexual. The skulls of the females examined are shorter and more in- 

 flated in the rostral portion than those of the males. In this respect 

 they approach the Porto Rican m. inflata, but the skull of that form 

 appears, in both sexes, to be more inflated and robust proportionally 

 than the smaller females of madeayii.
