 other forms by the combination of these characters : —

 cusp or ledf^e ; no well-marked antero- internal ledj^e in m' ; 

 skull, total lcii<i;ih IS H-oir mm., maxillary tooth-row (c-m-,

 * Astrolal)e/ Zool. i. p. 8G, Atl. pi. xi.' Type locality, Am- 

 boina. In 1837 by Temminck declared indistinguishable 

 from Cejihnloti'S peroni (^lon. Mamm. ii. p. lOD), an opinion 

 unhesitatingly accepted by all otiier revisers. — Is a dis- 

 tinct species. Diagnosis : — Anfero-internal corner of m, 

 not differentiated as a distinct cusp or ledge ; general size 

 nnusually large, forearm 1335-141 mm. Range : — Ruru, 

 Amboina, Ceram, Aru Islands. 



Nearly half a century passed without further additions to 

 the list. The three principal revisers of the genus during 

 this long period, viz. Peters in \Hi\7 (MH. Akad. Berlin), 

 Gray in 1870 (Cat. Monk, kc), and Dob-son in 1878 (Cat. 

 Chir. H. M.),coi)ied Temminck in recognizing only one species, 

 Ceplialotos fieroni, with the synonyms Fteropus ixiUlatus and 

 Hypodernia ino/urccnse. 



1879, Ccphalolcs minor, Dobson, P. Z. S. 1878, p. 875. 

 Type locality, Ambeibaki, N.W. New Guinea. — A distinct 

 species. Differential characters : — Premolars and molars 

 simple (no well-marked antero-internal and posterior ledges, 

 no trace of surface ridges); smallest species known, forearm 

 about 80 mm. — The type in the Paris Museum was hitherto 

 the only specimen known to exist in collections. There is, 

 however, a second specimen in the Leyden Museum {"Crpha- 

 lotes peroni " rr, with skull dd), collected by Dr. Bernstein, 

 but unfortunately without locality; as having been acquired 

 by the Leyden Museum in 187(5, years after the explorer's 

 death, it proi)ably dates from his last voyage, and, it' so, it 

 must have been ohtiiined either in Sorong (N.W. New 

 Guinea), Salawati, Batanta, or neig]\l)ourliood (sec his
