Matscliie's Thylogah lauterbaclii, on tlie otlier li.iiul, also 

 from this part of New Guinea, seems to be a low-country 

 form, with short fur only 15 mm. in length. A skin of it, 

 without skull, was obtained by Mr. Keysser on the Sattelberg.

 in length. General colour above dark shining cliocolate- 

 brown, near " ^lars-brown," not the more smoky greyish

♦ With some hasitation I accept Matscbie's separation under the above 

 name of the macleayi group of iJotcapsis, on account of the short muzzle 

 of the skull, the less elongate secator, which only just equals m^ + tn' 

 instead of j/j'-f r/r+half t)i^, and the more extended and abrupt nakedness 

 of the tail.
