170 Records of the Indian Museum. [VoL.-V, 
species from Singapore which is here regarded as belonging to the 
Malay Peninsula) out of the known 66 specifically identified forms 
occurring in these islands. Of these 33 species 14 are known from 
no other locality, nine of them—Cryftops modighani, Otostigmus 
longicornis, O. sumatranus, O. suckt, O. niasensis, O. nemorensts , 
Rhystda monticola, Anodontostoma octosulcatum, and Scolopendra 
gracillima—being confined to the Sumatra-Java-Borneo group of 
islands, one—Otostigmus punctiventery—being common to these and 
to the Philippines, one—Cormocephalus philippinensis—being res- 
tricted to the Philippines, and three—Paracryptops webert, Otostig- 
mus geophilinus and O. multidens—extending beyond the Oriental 
region to Flores, Timor and Celebes, respectively. Of the remain- 
ing 19 species found in the Oriental section of the Malay Archi- 
pelago, the distribution of 2 seems to extend eastwards only— 
that of Otostegmus asper from the Philippine to the Marianne Islands ; 
and that of Otocrvptops melanostomus from the Philippines and 
Java to Porto Rico and Argentina, though no records have yet 
been made between N. Guinea and Venezuela. It is perhaps 
worth noting here that the only other species of Otocryptops 
included in the above list of Oriental species, O. rubiginosus, has a 
parallel distribution further to the north, extending from China 
through Japan to N. America where, however, it has apparently 
only been recorded from the states of Minnesota and Indiana— 
more than half way across the Continent. There are I0 species 
found both east and west of the Malay Archipelago. Of these 
Scolopendra morsttans occurs throughout the tropical and tem- 
perate zones; S. subspinipes shares the same extensive area with 
the closely allied S. cingulata which replaces it entirely round the 
Mediterranean Sea; and Rhysida longipes occurs throughout the 
tropical zone, being found in India as far north as the Nepal Terai 
but not in the Himalayas. Otostigmus poliius is found from 
China and the Eastern Himalayas to Australia; Cryptops dorie 
from Burma to New Guinea; Rhysida nuda from Burma and 
Ceylon to Australia (also in Paraguay); Rhysida carinulata from 
the Malay Peninsula to Australia; Ethmostigmus platycephalus 
from Eastern India (Madras Presidency) and Burma to New 
Britain; and FE. rubripes from China and Java (no intermediate 
records as yet) to Tasmania and the Solomon Isles. And Ofostzg- 
mus astenus, which extends from the Philippines to New Caledonia 
and Australia, has in addition been recorded from the Seychelles. 
Of the 7 remaining species occurring in the Malay Archipelago 
one—khysida tmmarginata—occurs throughout India, Burma and 
Oriental (not eastern) Malaysia ; one—Otostigmus insularis—in the 
Philippines, E. Himalayas, Ceylon and the Seychelles ; four— 
Otostigmus aculeatus, O. spinosus (found also in Algeria !), Ethmo- 
stigmus bisulcatus and Cryptops inermipes—have only been found 
in the Burma-Cambodia region on the mainland (there appears 
to be some doubt, however, as to the occurrence of Cryptops 
inermipes there at all) and in the Sumatra-Java-Borneo group 
of islands of the Archipelago; and the seventh—Ofostigmus
