tlieso toes, the variation iu this respect beiiifi; to a hirge exieut 

 individual (in t3'pical liouseftus inserted on first toe, in the subgenus 

 Steiinni/rteris on second). Vertical fascife of mesopatagium few in 

 number (about 9-12), ver)' thick, and widely spaced, quite as in 

 typical Ho'isetiits. Second digit without claw (present in Bousttlus), 

 the third phalanx wholl)- included in the membrane; relative lengths 

 of mat.acarpals and phalanges very nearly as in typical lionsetlns, 

 but l^ontjrtf.rls perhaps a shade more primitive iu so far as the 

 dilTerence in length of the third (longest) aud fifth metacarpals has 

 remained a little greater than in typical Romettas (compare tabic 

 below, showing in upper row the wing-indices of Eonyderis, 

 calculated from 17 adult specimens, and iu lower row those of 

 typical Ronsettiis for comparison). Distribution and colour of fur 

 as in llouscttiis J.enchi and allied species (tibia naked ; back some 

 tinge of dark brown, underside paler, often hair-brown). 



Sexual differentiation. — (1) Sides of neck and forcneck in 

 females tliinly clothed, the skin usually showing through; same 

 region in adult males covered with a well-marked "ruff" of 

 longer hair, the colour of which is generally a shade deeper (more 

 saturated) than that of back and clicst. (2) Jlales averaging 

 larirer than females (soh tables of measurements i)p. 7-l."3, 744). 



Range. — From Burma and Siain, south through the Malay 

 Peninsula, to Sumatra and Java, east to Borneo and Celebes. 

 Unknown from the Philippines and (thus far) from the islands 

 cast of Java. The whole region from Burma and Siani through 

 the Malay Peninsula to Sumatra and Java is occupied by one 

 s])ccies, h'. spehi'u ; the two other species are as yet (liJll) known 

 only from the type specimens, E. major from Borneo, E. rosenben/i 

 from Celebes. 



Ila.hits. — In the later months of the year 1907 a group of 

 flowering Ar/ave in a garden at Pasir Datar, Java, was visited 

 regularly every night by a considerable niimbei' of E. speliea. 

 They were noticed dodging swiftlj' about among the iiiHorescenees, 

 alighting now and then, but always for a few moments only, 

 on the flowers (which are remarkable for their long projecting 

 stamina), and so persistent Avas their prerlilection for this par- 

 ticular group of plants that neither shooting nor artificial light 

 would frighten them away. The stomach of one specimen 

 (examined by Dr. Yaleton, Botanic Gardens, Buiteuzorg) was
