especially from Burma. The Sumatra-specimen agrees in size, color 
and all other characters exactly with the description given by Dobson 
of the type-specimen. 
Macroglossus. 
Macroglossus minimus Geoffroy. 
Sumatra: Sumanik near Singkarab; skin: 173, cf (47 Mm.). 
In all dimensions a good deal larger than the adult female measured 
by Dobson (Catalogue, p. 96). 
Phyllorhina. 
Phyllorhina diadema G-eoffroy. 
Central-Celebes : Palopo, Luwu; skin: 585, Q (92 Mm.). 
The late Mr. Teysmann collected this species in Celebes (Catalogue 
des Mammiferes, 1888, p. 166), and as far as I am aware there are 
in other Musea no specimens from Celebes, except these Teysmann- 
specimens in the Leyden Museum. 
Phyllorhina bicolor Temminck. 
South Celebes : Cave Bulu Sipong, near Maros; skin: 3, 9 (41 Mm.). 
In the Notes from the Leyden Museum, 1883, p. 174 I have 
mentioned this species from North-Celebes. The specimen collected by 
Prof. Weber is therefore the second known one from Celebes and the 
first specimen from South-Celebes. As the length of the fore-arm in* 
dicates, our 9 is much larger than one of the specimens of which 
Dobson gives measurements in his well known Catalogue, p. 150. 
In our female-specimen are two good developed anal-mammae. If I 
remember rightly, I often have seen in other Bat-species mammae in 
the neighborhood of the orifice of the female sexual Organs , but seldom 
I saw these parts so well developed as in the adult female under 
consideration. We may ask what may be the function of these anal- 
mammae? It is well known, as Dobson remarks in his Catalogue, 
that many species of Bats have occasionaliy two young at a birth 
and he thinks it probable that where two young are born in a single 
birth the male relieves the female of the Charge of one and at the 
same time performs the Office of a nurse ! I think we are here placed 
before a very interesting biological problem, which can be solved only by 
studying the animals in their natural behavior. It seems to be very 
difficult to find out any concordance between a female- bat, with four 
mammae and two young, and a malebat officiating as nurse.
