KM "S^W 1. LIST OF MICROCHIROPTERA, OTHER THAN' LEAF-XOSE BATS. IN THE COLLECTION OF THE FEDERATED MALAY STATES MUSEUMS. By Oldfield Thomas, F.R.S. ,1 owe to the kindness of Mr. H. C. Robinson the oppor- tunity of examining certain of the bats preserved in the collection of the F.M.S. Museums, and at his suggestion I have written the following list. It contains the Microchiroptera other than the Leaf-nose bats, with which latter Dr. Andersen is dealing. By the generosity of the authorities of the F.M.S. Museums the British Museum has been permitted to retain a number of the specimens here enumerated, including the tvpes of the three new forms described. Eptesicus dimissus, sp. nov. Eptesicus pachyntis, Robinson & Kloss, Journ. Fed. Malay States Mus. V. p. 116 119141. Type. 9 in al. Kao Nawng, Bandon, Malay Peninsula 3,500'. June 1913. F.M.S. Mus. No. 529/13. Collected by H. C. Robinson and E. Seimund. A medium—sized species related to E. pachyotis. Size rather greater than in E. pachyotis. Body proportionally rather larger compared with the wings. Fur short (hairs of back about 3 mm. in length 1, rather >parse, mostly confined to the body except on the interfemoral, on a triangle at the base of the tail. Colour chestnut brown above, lighter below, the haiis of the mesial area of the understirface broadly tipped with dull whitish or huffy. Ears short, rattier narrow, inner base with a rounded basal lobe; inner edge slightly convex, tip rounded off, outer edge straight above, convex lower down, with a low antitragal lobe. Tragus short, its inner margin, which is scarcely longer than its breadth, slightly concave, tip rounded, outer margin convex with a fleshy basal lobe. Wings to the middle of the metatarsals. A distinct post-calcarial lobule. Skull broad and stoutly built, with a well marked occipital "helmet." Upper incisors with less disparity 111 size than in the allied species, the tip of the outer attaining three fourths the height of the inner, the latter rather small but still of the characteristic Eptesicus shape, parallel sided, bicuspid ter- minally; the outer tricuspid, obliquely concave. Last lower molar with its posterior portion nearly equal to the anterior part in area, and similar to it, as in nvst of the smaller species of the genus Dimensions of the type, measured on the spirit specimen. Forearm, 42 mm. 2 JoUmul of the F.M.S. Museums. [Vol. VII, Head and body, 57; tail, 39; ear, 14; tragus, length on inner edge 3, width 2-3. Third finger (epiphyses not fully ossified), metacarpus 39; first phalanx, 15; lower leg and hind foot with claw, 25.5 mm. Skull, greatest length. 17.4; condyle to front of canine 15.8; basi-sinual length, 12.4; palato-sinual length. 6.3; front 3 of canine to back of m , 6.2 mm. Habitat and Type, as above. This bat has been determined as E.paphyotist Dobs, of Assam, to which it is no doubt closely allied. But it may be distinguished by its larger size (the type being barely adult), the attachment of the wing membrane to the middle of the metatarsus instead of to the base of the toes, and by its proportionally much larger outer upper incisor.

These specimens quite agree with Dobson's description of the type from Tenasserim. A rather strongly maikeri naked pad or wart just under the symphysis mcnti is not mentioned by the describer, but is present in all the specimens. Scotophilus castaneus, Horsf.

Straits of Malacca. 11 ,, 14 ., Pulau Angsa, Coast of Selangor. 12 ,, Batu Caves, Selangor. Essential characters as in true melanopogon, but colour both of fur and membranes far paler. Cieneral colour above pale brown, near " avellaneous " of Ridgway, varying a good deal in intensity, the hairs white for the greater part of their length, avellaneous termin- ally, or with their extreme tips again light. Undersurface "drab grey," the black beard when present contrasting markedly with the general light colour of the underside. In some specimens the brown parts of the upper hairs may be considerably darker, but never or very rarely as dark as in ordinary melanopogon, the average colour of all Peninsular and Straits specimens being conspicuouslv lighter. Membranes pale brown throughout. Dimensions of type : —Forearm 60 mm. Head and body (measured in flesh) 80; tail 25, ear 17. Skull, greatest length 21 ; condvle to front of canines 20, front 3 of canine to back of m 9. Habitat. Islands and coast of the Straits of Malacca. Type from Pulau Terutau. Type. Adult male. F. M. S. Mus. No. 391/12. Original number 5,163. Collected 1st December. 1912 by native collector. The light colour of the fine series of this bat is in striking contrast to its dark hues elsewhere. A large number of specimens are in the British Museum from other parts of the range of T. melanopogon; but none show the peculiar pallor of the present set. The Terutau specimens average on the whole the lightest, then those from Pulau Angsa, and the Batu Caves, Selangor. Other peninsular examples, of which there are few available, appear to average rather darker than in the extreme of fretensis. lighter than in true melanopogon.
