NOTES. 11] 
The common species in Ceylon is identical with one found 
abundantly during the rains, and more rarely in dry weather in 
the compound of the Indian Museum, Calcutta. I have already 
described it (1910) under the name Seutigerella unguiculata, Hansen, 
sub sp. indica, and recorded its known distribution. 
On going through my Ceylon material prior to incorporating it 
in the general collection of the Indian Museum, two specimens of 
another species of Symphyla—=Scutigerella orientalis, Hansen— 
were discovered. Hansen records the species from Java, Sumatra, 
Koh Chang Island (Gulf of Siam), and Bankok ; but I know of no 
previous record from Ceylon. These two specimens were found 
at Pattipola on July 2 or 3 of this year (1910), but I have no 
recollection of the circumstances under which they were found. 
It is, however, almost certain that they came from the jungle, as 
almost the whole of my collecting was done there. S. orientalis 
is both longer and stouter than S. wnguiculata (indica), this difference 
being very evident even to the naked eye. The latter attains a 
length of little (if at all) over 4 mm.; but my specimens of the 
former are both about 6 mm. long. ; 
The Symphyla are always minute, but when examined under a 
strong hand lens they can at once be distinguished from the young 
of other centipedes by the presence of a pair of (stout and unjointed) 
cer¢ei, which project backwards from the last segment of the body. 
Hansen (1904) gives tables, descriptions, and figures, from which it 
is easy to identify any of the species known to him. Since he wrote, 
Imms (1908) has described one additional Oriental species, Scuti- 
gerella subunguiculata, found by himself in the Himalayas; and I 
have described (1910) the common Ceylon and Calcutta form— 
S. unguiculata (indica).
