UNGUICULATA, HANSEN, FOUND 
TEN CA CWT 1A: 
By F, H. GRAveLy, M.Sc., Assistant Superintendent, Indian 
Museum. 
When hunting for insects under pieces of brick round the 
Museum tank between March 10 and March 19 of this year (1910), 
I was fortunate enough to find, close to the water’s edge, six 
specimens of a little white centipede which proved to belong to the 
interesting genus Scutigerella, and to Hansen’s Venezuela species 
unguiculata (Hansen, 1904, pp. 34—36, pl. ii, figs. 2a—2k). 
The only previous record of any specimen of Symphyla from 
the Museum compound—or indeed from Bengal—was made by 
Wood-Mason (1876, p. 175), who ‘‘ exhibited specimens of a species 
of Iapyx which he had recently found amongst the decaying 
leaves and fungi at the foot of a bamboo-clump in his own garden 
at Calcutta,’’ and mentions as one of the creatures found in asso- 
ciation with it ‘“‘ a species of the very remarkable genus Scolopen- 
dvella.”’ ‘This record appears to have been made in the month of 
August when the ground would be much wetter than in March, 
and as the few remaining bamboo-clumps in the garden are at 
present much too dry to harbour Symphyla at their base, it seems 
reasonable to suppose that this so-called ‘‘ Scolopendrella”’ 
was in reality the species of Scutigerella—this genus was not yet 
established when Wood-Mason wrote—which now occurs beside 
the tank. Its present distribution round the tank appears to be 
extremely limited, however, for it has only been found near 
the north-east corner, although I have carefully searched for it 
along all four banks. Since writing the above I have also found a 
few specimens in the drier neighbourhood of the rubbish-heap near 
the north-east corner of the tank. 
The only named species of Symphyla previously known from 
India is Scutigerella subunguiculata, Imms, which was found at a 
height of about 9,000 feet up in the Himalayas in the native state 
of Tehri Garhwal (Imms, 1908). ‘This species, as its name suggests, 
is very closely allied to S. unguiculata, and it is curious to find 
that the Calcutta specimens depart from the typical form of the 
latter in the direction of this Himalayan species. Thus, though the 
two species may be most easily distinguished from each other 
by the form of the claws of the twelfth foot, in the Calcutta
