Pteropus lavellanus, sp. n. 



Allied to Pt. rubianus, but cingulum of upper and lower 

 canines broader, general size of animal smaller, tibia rela- 

 tively much shorter (65*5-67'5 mm., against 76*5 in Pt. rubi- 

 anus), colour of fur darker. Back glossy seal-brown; rump 

 varying from cinnamon-rufous, through cinnamon, to nearly 

 orange ochraceous buffy, in any case strongly contrasting

Type. <J ad. skin and skull, Vella Lavella, Central Solo- 

 mon Islands, 12th March, 1908 ; collected by A. S. Meek. 



Specimens examined. Three, in the collection of the British 

 Museum. 



Range. Known from the type locality only. 



Remarks. — The differential characters given above are 

 based on a comparison with Pt. rubianus. From Pt. grandis 

 (Shortland Island and Bougainville), which it closely 

 resembles in the colour of the neck, back, rump, and under- 

 pays, Pt. lavellanus is readily distinguished by its smaller 

 size (forearm of Pt. grandis 167-172 mm.), relatively shorter 

 tibia (in Pt. grandis 76"5 mm.) and smaller ears, and by 

 having the crown and face grizzled buffy, greyish, and dark 

 brown, not uniform blackish or seal-biown as in Pt. grandis.
