13. Phalanger lullulae * sp. nov. 



Many specimens. WooiHark Island. 



A small discus of the Fit. orientalis groiij), spotted with white as in Pli. ornatus, 

 bnt without rufous on foreqnarters or belly. 



Size small, barely exceeding that of Pk. birviceps. Sexes almost exactly 

 alike, both in size, coloration, and even in the cranial characters. Ears small, 

 rounded, not so absolutely naked inside as is normal in the group, as there are 

 a few thinly scattered hairs on the internal surface of the ear-conch ; nothing like, 

 however, the thick hairiness found in the Ph. maculatus group. Fur very close and 

 woolly. General colour (of both sexes) dull brown, irregularly mottled with sjiots 

 of yellow or white, which increase iu number on the sides and Ixdly, so that the 

 latter may be said to be white mottled with brown. 



Chest and inner sides of limbs more white, but in the female the dark pre- 

 dominates on the lower part of the belly and inner sides of the hind-limbs. 

 Tlironghout, however, the mottling is so irregular that no exact description can be 

 drawn up. A dark nuchal or dorsal streak present, but very irregular, most distinct 

 on the crown. Tail rather more than a third hairy above, the difference between the 

 ujipcr and lower extension of the fur rather less than two inches. Mammae four. 



Skull on the whole very like that of Ph. or/e/iti/li.^, but the zygomata distinctly 

 converge forwards, so that there is a sort of elbow at their hinder ends, just external 

 to the glenoid fossae, and at this point the zygomatic breadth is decidedly greater 

 than in front. The snpraoibital crests are rather intermediate in character between 

 those of Ph. orientali.% and Ph. bren'ccps, more transverse!}' develoj)ed than in the 

 latter, less than in the former. Nasal notch deeper than in Ph. orii'ntaUs, almost 

 as in Pk. ornatus. 



Teeth apparently as usual, the upper canines jiresscd close against ?. not 

 separated as in Ph. ornntua. In all of the three skulls examined there are only two 

 upper premolars, no small teeth being present between the usual anterior and jiosterior 

 ones ; below, the greatest number of the small intermediate teeth present is three. 



Dimensions of the type, an adult male, in skin :— Head and body 375; tail 275; 

 hind-foot 51. A specimen in spirit has the car 21 '5 and lower leg 84 mm. 



Skull : basal length 68 ; greatest breadth 48-5 ; nasals, length 28, greatest 

 breadth 11; interorbital breadth 12-2; intertemporal constriction 8-3; palate 

 length 41 ; palatal foramen 5-6. Teeth, horizontal length of p* 4-G ; length of 

 ms'-^ 13. ~ 



Type: Brit. Mus. 96.11.5.24. Paratypes iu British and Tring Museums. 



It is difficult to decide whether this very distinct Cuscus is most nearly allied 

 to Ph. orientalis or Ph. ornatits. It resembles the latter in its white spotting and 

 deeper nasal notch, but is without any trace of the handsome rufous or orange on 

 the foreqnarters and belly, and its canine is as in Ph. orientalis. Its sujiraorbital 

 ledges also have more resemblance to tlioso of Ph. orientalis than to the very 

 remarkable ones of Ph. ornatus. 



14. Phalanger orientalis kiriwinae snbsp. nov. 

 Many specimens. Kiriwina Inland, Trubriaud grouj). 



Closely allied to the Fergusson Island snbsp. intercastellaiius, but rather larger, 

 and with a different structure of the interorbital region. 



' I^ullula, a woodlark.
