Collection of Bats from Para. 191 
This form may be readily distinguished from the typical 
Guianan planirostris by the darker colour of its chest and 
belly, and the different form of the anterior part of the skull. 
Micronycteris minuta, Gerv. 
Five. 
This striking species may be readily recognized, firstly, by 
its minute middle lower premolar, shown in Gervais’s figure 
but not mentioned by him, Dobson, or Miller; and, secondly, 
by the very peculiar structure of the connecting band between 
the ears. ‘his in some species is almost obsolete, in JZ. 
megalotis is low and has a shallow notch at its centre, while 
in MW. minuta it is very high and so deeply notched in the 
centre that it is practically divided into two prominent 
triangular lappets, one attached to each ear. ‘This character 
does not seem to have been noticed by anyone, though it 
occurs in all the specimens determined as Schizostoma 
minutum by Dobson. 
The forearm of the type was said by Gervais to be only 
32 millim., but on remeasurement by Dobson was put down 
as 1°35 in. (= 34°5 millim.). The present series are rather 
larger (36 millim.), but so are others trom close to the typical 
locality. 
Phyllostoma hastatum, Linn. 
‘Twenty-one. 
Phyllostoma elongatum, Geoff. 
Two. 
Hemiderma perspiciilatum, Linn. 
Thirty-eight. 
For nomenclature see below. 
Glossophaga soricina, Pall. 
Ten. 
Artibeus planirostris, Spix. 
One. 
Artibeus concolor, Pet. 
Two. 
From the meagre description given by Peters, there seems 
to be no reason to distinguish the Para specimens from his 
Guianan species. 
Artibeus bilobatus, Pet. 
Two.
