The chief character of tliis form is the shape of tlie nasal 

 swellings: in front view the upper surface of the swellings is 

 almost completely liat, the outline being a straight horizontal line, 

 and the width of the swellings at to]) is only a liltle less than 

 Iheir width at l)ase; in h'h. ai'cuatus arcuatus nnd exigu/(S {^) 

 the outline of the ujiper surface of the swellings, in front view, 

 is strongly convex, and Ihe width of the sw(dlings at to]) nnich 

 less lhan at base. The skull of beccm'ii is a{)j)arrntly on l]u' 

 whole rather broader than in llie other known forms of the s})ecies: 

 widlli of brain-case at root of zygomala '.>.^ nun., against H.S in

 nasal swellings ."i.cS, against ^i.o-o.T. lint in all otlu r res})ects 

 (cranial, dental, external, including dimensions) l^li. a. heccarli 

 is so completely similar to Rh. a. arcuatiis that, notwithstanding 

 the different sliajn^ of the nasal swellings, for the jtresent at least, 

 I ]>refer to j)ut it down as a local race of Uli arcuati'S, 

 i-ather than as a distinct s})ecies. 



Tliis is the first record of any form of Hh. arcualus from 

 Sumatra; the species was hitherto known from the I'hilii^pines oidy.
