1888.] OF THE SOLOMON ISLANDS. 471 



Shortland Island. The present individual agrees in every respect 

 with the type. 



2. Pteropus ^ HYPOMELANus, Tcmm. 



No further specimens of this species were obtained, and Short- 

 land Island remains therefore its only known locahty within the 

 group. 



^ The following new species of Pteropm from the Duke of York Archipelago 

 may also be conveniently described here : — 



Pteeofus coronatus, sp. n. (Plate XX. fig. 2, Plate XXI. figs. 2, 3.) 



Ears of medium length, naked, projecting much beyond the rather short fur ; 

 their anterior edges far less convex than their posterior, their tijis bluntly 

 pointed. Wings arising on the back only about half an inch apart. Inter- 

 femoral membr.ine narrow, concealed in the centre by the fur. 



Whole of head and neck very pale buff, nearly white on the crown between 

 the ears and above the eyes. Face ornamented with a prominent brown T- 

 shaped mark, of which the cross-line runs transversely across the forehead 

 halfway between the eye and ear, and the upright runs down the centre 

 of the face between the prominent white supraorbital patches, and extends 

 forwards about one third of an inch in front of the anterior canthus of 

 the eye. Eyelids and muzzle nearly naked, brown. Cheeks and chin dark 

 blackish brown. Front of neck, chest, and centre of belly very pale brown, 

 scarcely darker than the nape. Sides of belly and pubic region darker brown. 

 Posterior back blackish brown, mixed with dull yellowish ; the fur closely 

 adpressed, and only about one inch broad at the narrowest part. Fore limbs 

 and membranes nearly naked above, a few hairs only extending along the upper 

 side of the humerus and forearm ; upper and posterior sides of the thighs 

 thickly fm-ry ; lower leg naked. Bolow the fur covers the antebrachial mem- 

 brane, the humerus, femur, and the wing-membrane internal to them, and also 

 passes along the outer side of the forearms in a band about one inch wide. 



Teeth (Plate XXI. figs. 2, 3) unusually strong and heavy, smoothly rounded, 

 without basal cusps. Canines very long and sharp, their basal ledges obsolete. 

 Anterior upper premolar very minute, but still persistent in the type. Other 

 premolars very short horizontally, their breadth almost equal to their length. 

 Last molars, both above and below, comparatively large, above about one 

 fourth and below about one third of the penultimate molars. Anterior lower 

 premolar about half the size of the last molar, separated from the canine and 

 next premolar by diastemata each about equal to its own diameter. 



Dimensions of the ty|3e, an adultmale in spirit : — Head and body 243 millim. ; 

 head 77; tip of muzzle to eye 29; ear 24x16; forearm 167 (=6-6 in.); 

 thumb without claw 66 ; lower leg 76 ; calcaneum 26 ; foot b&n. 



Skull : — Basal length 69 ; greatest breadth 383 ; interorbital breadth 9-9 ; 

 palate, length 43, breadth outside m.^ 213, inside m.- 12-5 ; basi-cranial 

 axis 22'2 ; basi-facial axis 49. 



Teeth : — Combined breadth of upper incisors 7'7 ; vertical length of upper 

 canine, from cingulum to tip behind 10'6 ; horizontal length of large anterior 

 premolar 50, of posterior premolar 5"0, of first molar 6'5, of second molar 3'8. 



Hab. Mioko Island, Duke of York group {Dr. 0. Finsch), 13/3/85. 



This very handsome species has a certain superficial resemblance to Pt. ocularis. 

 Peters *, of which I have examined the type, an old male, in the Berlin Museum. 

 That animal, however, is distinguished by having a forearm only 137 millim. 

 long, by its much smaller teeth t, and by many detailed differences in coloration, 

 among which may be specially mentioned its wholly black underside, the black 

 extending all over the front of tlie neck. 



* MB. Ak. Berl. 1867, p. 326. 



t Couibined breadth of four upper incisors 57 millim. ; length of upper 

 canine 6'9, of last upper premolar 3'6.
