it approaches the subgenus Centronycteris, and the nakedness 
of the interfemoral will readily distinguish this bat from any 
of its allies. 
Scturus Ingrami, sp. n. 
Size about as in “ S. estuans cuscinus” and S. trroratus, 
larger than in the true S. estwans. Fur longer and looser 
than in S. wstuans, hairs on back about 12 millim. in length. 
General colour above finely grizzled olivaceous grey, varying 
somewhat towards brownish; the individual hairs blackish, 
with yellow subterminal rings. Head like back. Eyes 
surrounded by whitish rings. Kars rather more fulvous, the 
hairs dark basally, with fulvous tips. But little or no trace 
of a yellowish postauricular patch. Chin and throat white. 
Chest and belly pale buffy, varying almost to white, the hairs 
sometimes plumbeous basally, sometimes buffy to the roots ; 
line of demarcation on sides not sharply defined. Outer side 
of limbs and upper surfaces of hands and feet like back, the 
digits tending rather more towards yellowish. Inner side of 
limbs buffy, like the belly. Tail-hairs broadly ringed for 
their basal two thirds with dull fulvous and black, their distal 
thirds black subterminally and yellowish white distally, the 
two latter colours giving the general tone of grizzled black 
washed with yellowish to the tail as a whole. Mamme 8, 
one pair in or close behind the axilla, two pairs on the belly, 
and one in the groin*®. (‘Three females examined.)

‘This species is no doubt the “Securus estuans” of Wagner, 
Burmeister, Hensel, Pelzeln, Winge, and other writers on 
Brazilian mammals; but Linnzeus’s description is based on 
the squirrel of Surinam, which is decidedly smaller and both 
in colour and other characters is clearly a different animal. 
Shaw’s “ Myovus guerlingus”’ is also Guianan in origin. 
* One specimen has an additional anterior mamma on the right side
