,SltS ADDENDA A>'D CORRIGENDA. 



probable affinities of the five species here under discussion may be 

 briefly summed up as follows : — Ft. grisens (Timor, Bonerato, 

 Dyampea) is in the Philippine group represented by Pt. |mm(7i(s, 

 and both are probably closely allied to Pt. Hops (Amboina group), 

 which in Formosa is represented by Pt. formosiis and in the South 

 Liu-kius by Pt. dasipnalhis. To these may perhaps be added, as 

 an aberrant form of the dasymallus type, the Mascarene Pt. sub- 

 niger.

Add the following species : — 



29 bis. Pteropus voeltzkowi, Matschie. 



Ptevopiis (Spectnun) vueltzkowi, SlafscJiie, SB. Ges. nut. Fr. 1909, 

 p. 486 (Pemba I.). 



DiaipiGs'is. — Closely allied to Pt. oomorensls, but skull differing 

 in a few details (see below), ears much shorter, and mantle, sides 

 of neck, and underparts much darker. Size as Pt. comorensis, 

 forearm about 151-101 mm. Bab. Pemba Island (north of 

 Zanzibar). 



SJatll and dentition. — General size of skull as in Pt. comorennis, 

 characters the same -with the following modifujations : llostrum 

 relatively somewhat broader, postdental palate a little longer, 

 mesopterygoid fossa conspicuously broader (8o-9-7 mm., against 

 7-2-8 in Pt. comorensis), orbits slightly smaller (12*2-12-8, against 

 12-8-13"2), supraoccipital more sloping downward-and-backward 

 (practically vertical in Pt. comorensis), -occiput therefore more 

 strongly tubular. Teeth scarcely differing from those of Pt. como- 

 rensis, not even in size. 



Palate-ridges (examined in two individuals). — 5+5-|-3, in one 

 skull with an incomplete additional ridge between the ninth and 

 tenth (/. e. between the fourth and fifth of the divided set). 



^Vn-A'.— Much shorter than in Pt. comorensis, but not differing in 

 shape (subacutely pointed) ; length from orifice 21-5-23 mm., 

 against 31-5 in Pt. comorensis. 



Colour. — Paratype (aged, March, skinned from alcohol, Eerlin 

 Museum) : Eack and rump nearly uniform blackish with a tinge of 

 seal-brown ; a few silvery greyish white hairs detectable on close 

 examination. Breast and belly some tinge of russet or vandyck- 

 brown, palest (approaching cinnamon-rufous) on sides of belly, 

 darkest (very nearly vandyck-brown) on breast and middle of belly ; 

 flanks seal-brown ; concealed subapical portion of hairs on breast 

 and bellv ochraceons-buff, extreme base dark brown. Mantle 

 russet, somewhat clouded with vandyck-brown, shading into darker 

 vandyck-brown on sides of neck and foreneck : concealed portions 

 of hairs oi mantle, sides of neck, and foreneck ochraceous-buff, 

 extreme base soal-brown. IJppersidc of head dark vandyck-brown,
