the magnifying-glass has a dim appearance and forms 
a contrast to the surrounding chitine. These 2 tactile 
hairs seem also to be characteristic to the order of 
Phrynide. 
In Phr. nigrimanus is seen on the metatarsus of 
the 3 pairs of legs, on the upper side, close to the 
basis 4 or 6 dark, small rings (Tab. II, fig. 12, a), to- 
wards the distal end similar rings arranged in 2 longi- 
tudinal rows (b), in the beginning converging, then 
close together, subsequently diverging and bending down 
the sides; close outside and between the distal end of 
the rows 3 further rings. On the upper side of tibia, 
in a little distance from the apex is found one single, 
similar ring. These darker rings surround a compara- 
tively large hole, out from which rises one long, ex- 
ceedingly thin, often worn sense-hair, the darker colour 
of the ring is partly owing to the darker tone of the 
surrounding chitine, partly to the circumstance that the 
scaly formations on the surface, otherwise spread, 
become smaller and placed more closely together round 
the hole. I have found similar tactile hairs in Admetus 
and Damon, reminding by their site of similar hairs in 
Aranee. They are most likely found in all Phrynide, 
but I have not examined if in their distribution syste- 
matic characters (for the genera or the species) may be 
found. 
C. Other Sense-Organs. 
Of these hitherto but the eyes have been known. 
In January 1893 Bernard (op. cit. p. 29—30) has 
published a preliminary note on an organ he has found 
in the proximal part of the claw of the maxillary palpi. 
I do not mention this but for the sake of completement, 
as Bernard holds out a prospect of further particulars ; 
I shall observe, however, that at all events it is not
