T?/2je.— B.M., No. 26.3.7.1 ; adult female, collected June 28, 

 1923, and presented by the Hon. Ivor Montagu. 



T'ljiJc locality. — -Zalesina, the Gorski Kotar, Croatia. 



Range. — Known only from the type locality. 



Characters.- — Size large (hind-foot 19 mm.; condylo-basal 

 length of skull 26-6 mm.). Tail relatively short, about 43% of the 

 head and body length. 



Fur of back long and shaggy. Colour above bright rufous, the 

 sides bright orange-brown so that the mantle is wide spreading 

 and ill defined laterally. Under surface grey, somewhat darker 

 than in the neighbouring races of E. glareolus. 



Skull peculiarly long, narrow and smooth, the frontals in the 

 interorbital region flattened, with scarcely a trace of the super- 

 ciliary ridges. Zygomatic arches very little expanded, the 

 zygomatic breadth scarcely greater than the mastoid width, 

 curving away very gently from the rostrum in front. Rostrum 

 and nasals very long and narrow, the nasals rather like those of 

 E. cwsarius. Interorbital region broad ; the orbito-temporal 

 vacuities strikingly small. Braincase smooth, subovate, and well 

 arched ; post-orbital processes of squamosals small and weak, about 

 as in E. nagcri. Diastema and anterior-jjalatal foramina very long. 

 Tooth-rows long, the teeth narrow. Palate normal. Ptery- 

 goid fossae short. Auditory bullae very large, the tegmen tympani 

 and mastoid portion a little more inflated and swollen than usual ; 

 basiocciiDital between bullae narrower than in E. nageri and 

 E. ccesarius. Mandible normal. 



Cheek-teeth of normal pattern ; jh^ with three outer and 

 four inner salient angles, the third inner fold well developed. 



For external and cranial measurements, see tables at end of 

 volume. 



Remarks. — -This is a sharply distinguished member of the 

 nageri group. In skull form it approaches Asiatic representatives 

 of the groujJ like E. poniicus, but differs from all in various im- 

 portant ways. Among European forms its skull is readily dis- 

 tinguishable by its large size, smoothness, gently rounded outline, 

 slender rostrum and large auditory bullae.
