nlong the sides, midway between the edge of the ventral surface and tlie 

 middle of the back, and in having rather less white below. In No. 11412, 

 the color of the middle of the back is nearly uniform bluckish-brown, with a 

 quite well-marked grayish subdorsal band; the ear-patches are pure white, 

 and there are large areas of white on the ventral surface. In No. 11411, the 

 upper parts are dull faded reddish-brown instead of blackish-brown ; the light 

 lateral band is still better marked, and the white below is restricted to a spot 

 at each arm-pit Four other specimens are similar to the last, except that 

 the lateral band is more or less whitish, and the tail is more broadly edged 

 with white. The white of the lower surface is sometimes confined wholly to 

 the throat and breast, and sometimes forms a narrow, more or less interrupted, 

 mesial line, widening over the posterior part of the ventral surface. In No. 

 11421, the lower surface is rusty-yellow, with the upper parts paler than in 

 any of the preceding. No. 8506 (from Nicaragua) is wholly pale yellowish- 

 brown above and rusty-yellow below, with white arm-pits. Tlie above- 

 mentioned pale-grayish lateral band is placed high up on the sides, and does 

 not correspond in position with the usual "lateral line" which marks the 

 division of the ventral from the dorsal surface. 



As would be expected, these pliases of coloration have given rise to 

 numerous synonyms. Lesson's Macroxus adolphei and M. pyladei seem botli 

 referable here, the former agreeing with No. 11364, described above, except 

 that the f ntire lower parts are white instead of having the white restricted to 

 irregu\f large patches; the latter {M. pyladei) agrees closely with the usual 

 C'\,iSii Rican phase of this species, in which the ear-patches and the whole 

 lower surface are rufous,* Both were described from Central American
