 spicuously lengthened than usual — about, 3 in. in length, (reneral colour above 

 coarsely grizzled brown (between Front's brown and raw umber of l{idgway), tlie 

 hairs ringed with brown and orange ; where they lengthen on the rump they are

 D. istlimiva. Uudersiirface soiled yellowish, the hairs lioth of tiiroat and brlly 

 brown basally and yellow terminally. Crown blackish brown. Ears nearly naked, 

 the sparse hairs brown. Arms and legs like body, uppersurface of hands and feet 

 black. Tail naked, about an inch in length, and therefore decidedly longer than

 hindfoot, s.u., lUo, c.u., 116 ; ear, 32 ; sknll, upper length, IKT, basilar length, 78 ;

This species, like 1). punctata, has its long rump-hairs ringed, but the longer 

 orange tips to them give it a greater general resemblance to D. isthmica, with which 

 the body colour also better agrees. The throat and belly hairs of D. punctata are 

 ringed, while in D. isthmica they are as described above in D. coibae, 



Mr. Bangs' D. calUda from San Miguel belongs to the other grouji, having its 

 rnmji hairs unringed, as in D. istkmica.
