half — viz., Mysol, New Guinea, the Bismarck Archipelago, 

 Kej, Arn, Torres Straits, and Solomon Islands — by three 

 races [M. I. nanus, p?/9'mccw5, and microtus ; the two latter 

 new), which, all taken together, are characterized, as against 

 M. I. lagochilus, by still narrower cheek-teeth, and distin- 

 guishable from each otiier by average differences in the 

 length of the rostrum or size of the ears. 



The new forms may be briefly diagnosed as follows : — 



Macroglossus minimus sobrinus, subsp. n. 



Averaging conspicuously larger than M. m. minimus, and 

 witli relatively longer rostrum. Skull, lambda to gnathion 

 28"5-29*5 mm. (in M. m. minimus 2i'8-27'5), rostrum, 

 orbit to nares y-5-10-5 (7-8-8-8), forearm -12-48-5 (40- 

 44-5). 



Type. $ ad, skin with skull, Gunong Igari, Perak ; March, 

 1898; presented by A. L. Butler, Esq., B.M. 98. 11.29. 1. 



Total number of specimens examined, twenty-six (compared 

 with forty of M. m. minimus). 



Macroglossus lagochilus pygmceus, subsp. n. 



As M. I. nonus, but rostrum relatively a little shorter, from 

 orbit to nares 6*8 mm. (against 7*5-8'5 in nanus). 



Type. J ad. al. with skull, Mer, Murray Is., Torres Straits, 

 presented by Professor A. C. Haddon, B.M. 99. 9. 10. 1. 



Two specimens examined, both from Murray Is. 



Macroglossus lagochilus microtus, subsp. n. 



Similar to M. I. pygmceus, but ears relatively smaller ; 

 length from orifice 11-12*5 mm. (in nanus and 'pygmceus 

 12-5-13-5), breadth of flattened ear 8-8-5 (9-9-5). 



Type. ? ad. al. with skull, Aola, Guadalcanar, Solomon 

 Is., collected by C. M. Woodford, Esq., B.M. ^^. 1. 5. 14. 



Three specimens examined, from the islands of Florida 

 and Guadalcanar. 



II. The Species and Subspecies of Syconycteris. 



Seven recognizable forms, referable to three closely related 

 species, are now known, viz., S. crassa (with five local races), 

 australis, and naias (sp. n.). In S. crassa the cheek-teeth 

 are elongate in transverse section (p*, m^, p^, and ruj more 

 than half as broad as long), and m" and m^ are always present 

 (cheek-teeth |) ; the species ranges over the whole of the
