V. Wallach, A NEW SPECIES OF BLIND SNAKE, TYPHLOPS MARXI, FROM THE PHILIPPINES (SERPENTES, TYPHLOPIDAE), The Raffles bulletin of zoology, 41(2), 1993, pp. 263-278
A new species, Typhlops marxi, is described from northwestern Samar Is
land in the Philippines. It is placed in a species group of its own du
e to its unusual combination of features that do not indicate affinity
with any known group: 30 midbody scale rows, a laterally pointed snou
t with horizontal cutting edge, a supralabial imbrication pattern type
of T-0, and type B foramina in a multicameral tracheal lung. Three ne
w systematic characters are introduced from the ophidian respiratory s
ystem: the cardiac lung, morphological lung types (unicameral, paucica
meral and multicameral), and lung foramina types (A-G).
