 Dobsonia panuietensis, K, Andersen, Ann. S( Mag. N. H, (8) iv. 



pp. 530, 533 (1909: characters; affinities). 



Diaynnsis. — Similar to D. e~,voleia, bub rather smaller, with 

 noticeably smaller skull and maxillary teeth ; mediaa surface- 

 ridges distinct in m' and m.,, rarely (if ever) in m^. Forearm 

 abotic 109-112 mm. Hub. Trobriand, D'Entrecasteaux, and 

 Louisiade Archipelagos. 



SJcuU and dentition. — Skull similar to that of D. exoleta, but 

 conspicuously smaller and more delicately built ; total length 47- 

 48 mm. (against 52 in e-xoleta)., zygomatic breadth 28 (32), lower 

 jaw 37 (41-42-5), maxillary tooth-row, e-m'^ 19-8 (20-5-21-3).— 

 Dentition essentially as in exohta (inner ridge of m^ perfectly 

 simple, witliout trace of antero-internal basal ledge or cusp), but 

 maxillary teeth on the whole noticeably weaker ; length, antero- 

 posteriorly, of p^ 3*8-4-3 mm. (4-2-4'7 in exoleta), of p* 3"8-4"3 

 (4-3-4-8), of m' 4-8-5-2 (5-7-5-8). Median surface-ridges ob- 

 solescent or entirely absent in p* and m^, more or less distinct in 

 ni' and m^, but apparently never as well marked as in exoleta. 

 Inner cingnlum of m' peculiarly thickened, tending to form a basal 

 ledge or projecting keel along anterior third or half of inner 

 surface of tooth (ajjproximulions to this sometimes seen in D. exoleta, 

 moluccensis, and magna). 



Colour. — Ad. skin, Kiriwina, February, 96.11.5.7: Back of neck 

 dark drab-brown sli,i;htly tinged with wood-brown. Occiput, 

 crown, and sides of head dark shiny bistre. Underparts light 

 drab, approaching ecru-drab, and mixed with whitish grey and 

 light tawny-olive on breast and belly ; hair on underside of 

 membranes tinged with tawny olive. — An adult female from 

 Kiriwina, preserved in alcohol, is practically identical in colour. 

 An immature individual (skin) from same place is similar to the 

 adult skin, but with the new fur of the underparts of a warmer 

 ecru-drab tinge. Two immature specimens from Fergusson Island 

 come nearest in colour to this latter, but the general aspect is on 

 the whole u shade darker. 



Measurements. On pp. 477, 479, 481. 



Specimens examined. Five, as registered below. 



Range. Apparently generally distributed over the islands S.E. of 

 New Guinea ; as yet recorded from the Trobriand group (Kiriwina), 

 D'Entrecasteaux group (Fergusson), and Louisiades (Panniet). 



Cotijpes in the Queensland Museum, Brisbane. Species based on 

 one male and three females (skull of one) obtained in Panniet 

 Island, Ijouisiades. The cotypes have not been available for re- 

 examination, but f he description and measurements accord perfectly 

 with the specimens here referred to D. pannietensis, except in one
