REMARKS ON THE INSECTIVORES OF THE GENUS 



GYMNURA. 



By Marcus Ward Lyon, Jr.,

An examination of nearly two dozen specimens of the genus 

 Gymriura in the United States National Museum shows that in addi- 

 tion to the two distinct species usually recognized, a third form, from 

 the northern portion of the Malay Peninsula, must be considered. 

 It is here described for the first time as a subspecies of the older of 

 the two species. 



As there is some lack of agreement among authors regarding the 

 limits of the genus Gymnura^ it will not be out of place to con- 

 sider some of its characteristics before describing the new subspecies. 

 Dobson,* Flower and Lyddeker,'' and Trouessart '' have included 

 imder the term Gymnura certain small short-tailed species, which 

 other writers, Thomas'' and Max Weber,'' for instance, regard as 

 constituting a separate genus Ilylomys. I quite agree with the 

 opinion of these latter, and in order to show the distinctness of 

 Crymmira from Ilylomys figures of their skins and skulls are shown 

 on Plates 34 to 37. In order to make the relations of the genus 

 Gymnura still clearer, the entire animal and the extracted skull of 

 the unique specimen of the recentl}^ discovered and related genus 

 Podogymnura^^ an animal imknown to the authors cited, are shown on 

 the plates 3G and 37. 



Gymnura is here considered as one of three genera forming the 

 subfamily Gymnurinje, the other two being Ilylomys and Podogym- 

 wiira. In respect to size and external characteristics Ilylomys and 

 Podogymniuu appear to be closely related to one another. (Plate 37.) 

 An examination of the teeth, however (Plate 36), shows that these
